Moreover, in some + cases the selected textures may vary on a per-fragment basis within + a polygon. Several examples include: + + 1. High dynamic range textures. The application stores several + different "exposures" of an image as different textures. On a + per-fragment basis, the application selects which exposures are + used. + + 2. A terrain engine where the altitude of a point determines the + texture applied to it. If the transition is from beach sand to + grass to rocks to snow, the application will store each texture + in a different texture map, and dynamically select which two + textures to blend at run-time. + + 3. Storing short video clips in textures. Each depth slice is a + single frame of video. + + Several solutions to this problem have been proposed, but they either + involve using a separate texture unit for each texture map or using 3D + textures without mipmaps. Both of these options have major drawbacks. + + This extension provides a third alternative that eliminates the major + drawbacks of both previous methods. A new texture target, + TEXTURE_2D_ARRAY, is added that functions identically to TEXTURE_3D in + all aspects except the sizes of the non-base level images. In + traditional 3D texturing, the size of the N+1 LOD is half the size + of the N LOD in all three dimensions. For the TEXTURE_2D_ARRAY target, + the height and width of the N+1 LOD is halved, but the depth is the + same for all levels of detail. The texture then becomes an array of + 2D textures. The per-fragment texel is selected by the R texture + coordinate. + + References: + + http://www.opengl.org/discussion_boards/cgi_directory/ultimatebb.cgi?ubb=get_topic;f=3;t=011557 + http://www.opengl.org/discussion_boards/cgi_directory/ultimatebb.cgi?ubb=get_topic;f=3;t=000516 + http://www.opengl.org/discussion_boards/cgi_directory/ultimatebb.cgi?ubb=get_topic;f=3;t=011903 + http://www.delphi3d.net/articles/viewarticle.php?article=terraintex.htm + +New Procedures and Functions + + All functions come directly from EXT_texture_array. + + void FramebufferTextureLayerEXT(enum target, enum attachment, + uint texture, int level, int layer); + +New Tokens + + All token names and values come directly from EXT_texture_array. + + Accepted by the <cap> parameter of Enable, Disable, and IsEnabled, by + the <pname> parameter of GetBooleanv, GetIntegerv, GetFloatv, and + GetDoublev, and by the <target> parameter of TexImage3D, GetTexImage, + GetTexLevelParameteriv, GetTexLevelParameterfv, GetTexParameteriv, and + GetTexParameterfv: + + TEXTURE_1D_ARRAY_EXT 0x8C18 + TEXTURE_2D_ARRAY_EXT 0x8C1A + + Accepted by the <target> parameter of TexImage2D, TexSubImage2D, + CopyTexImage2D, CopyTexSubImage2D, CompressedTexImage2D, + CompressedTexSubImage2D, GetTexLevelParameteriv, and + GetTexLevelParameterfv: + + TEXTURE_1D_ARRAY_EXT + PROXY_TEXTURE_1D_ARRAY_EXT 0x8C19 + + Accepted by the <target> parameter of TexImage3D, TexSubImage3D, + CopyTexSubImage3D, CompressedTexImage3D, CompressedTexSubImage3D, + GetTexLevelParameteriv, and GetTexLevelParameterfv: + + TEXTURE_2D_ARRAY_EXT + PROXY_TEXTURE_2D_ARRAY_EXT 0x8C1B + + Accepted by the <pname> parameter of GetBooleanv, GetIntegerv, + GetFloatv, and GetDoublev + + TEXTURE_BINDING_1D_ARRAY_EXT 0x8C1C + TEXTURE_BINDING_2D_ARRAY_EXT 0x8C1D + MAX_ARRAY_TEXTURE_LAYERS_EXT 0x88FF + + Accepted by the <param> parameter of TexParameterf, TexParameteri, + TexParameterfv, and TexParameteriv when the <pname> parameter is + TEXTURE_COMPARE_MODE_ARB: + + COMPARE_REF_DEPTH_TO_TEXTURE_EXT 0x884E + + (Note: COMPARE_REF_DEPTH_TO_TEXTURE_EXT is simply an alias for the + existing COMPARE_R_TO_TEXTURE token in OpenGL 2.0; the alternate name + reflects the fact that the R coordinate is not always used.) + + Accepted by the <internalformat> parameter of TexImage3D and + CompressedTexImage3D, and by the <format> parameter of + CompressedTexSubImage3D: + + COMPRESSED_RGB_S3TC_DXT1_EXT + COMPRESSED_RGBA_S3TC_DXT1_EXT + COMPRESSED_RGBA_S3TC_DXT3_EXT + COMPRESSED_RGBA_S3TC_DXT5_EXT + + Accepted by the <pname> parameter of + GetFramebufferAttachmentParameterivEXT: + + FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER_EXT 0x8CD4 + + (Note: FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER is simply an alias for the + FRAMEBUFFER_ATTACHMENT_TEXTURE_3D_ZOFFSET_EXT token provided in + EXT_framebuffer_object.

This extension + only provides the minimal hooks required to implement a debugger. + + There are facilities to do the following: + 1. Have the GL call a user-specified function prior to executing + each vertex or fragment instruction. + 2. Query the current program string's execution position. + 3. Query the current values of intermediate program values. + + The main feature is the ProgramCallbackMESA function. It allows the + user to register a callback function with the GL. The callback will + be called prior to executing each vertex or fragment program instruction. + + From within the callback, the user may issue Get* commands to + query current GL state. The GetProgramRegisterfvMESA function allows + current program values to be queried (such as temporaries, input + attributes, and result registers). + + There are flags for enabling/disabling the program callbacks. + + The current execution position (as an offset from the start of the + program string) can be queried with + GetIntegerv(GL_FRAGMENT_PROGRAM_POSITION_MESA, &pos) or + GetIntegerv(GL_VERTEX_PROGRAM_POSITION_MESA, &pos). + + +IP Status + + None + +Issues + + 1. Is this the right model for a debugger? + + It seems prudent to minimize the scope of this extension and leave + it up to the developer (or developer community) to write debuggers + that layer on top of this extension. + + If the debugger were fully implemented within the GL it's not + clear how terminal and GUI-based interfaces would work, for + example. + + 2. There aren't any other extensions that register callbacks with + the GL. Isn't there another solution? + + If we want to be able to single-step through vertex/fragment + programs I don't see another way to do it. + + 3. How do we prevent the user from doing something crazy in the + callback function, like trying to call glBegin (leading to + recursion)? + + The rule is that the callback function can only issue glGet*() + functions and no other GL commands. It could be difficult to + enforce this, however. Therefore, calling any non-get GL + command from within the callback will result in undefined + results. + + 4. Is this extension amenable to hardware implementation? + + Hopefully, but if not, the GL implementation will have to fall + back to a software path when debugging. This may be acceptable + for debugging. + + 5. What's the <data> parameter to ProgramCallbackMESA for? + + It's a common programming practice to associate a user-supplied + value with callback functions. + + 6.

When SPRITE_POINT_MESA is enabled + a point is rendered as if it were a quadrilateral with unique texture + coordinates at each vertex. This extension effectively turns points + into sprites which may be rendered more easily and quickly than using + conventional textured quadrilaterals. + + When using point size > 1 or attenuated points this extension is an + effective way to render many small sprite images for particle systems + or other effects. + +Issues: + + 1. How are the texture coordinates computed? + + The lower-left corner has texture coordinate (0,0,r,q). + The lower-right, (1,0,r,q). The upper-right, (1,1,r,q). + The upper-left, (0,1,r,q). + + 2. What about texgen and texture matrices? + + Texgen and the texture matrix have no effect on the point's s and t + texture coordinates. The r and q coordinates may have been computed + by texgen or the texture matrix. Note that with a 3D texture and/or + texgen that the r coordinate could be used to select a slice in the + 3D texture. + + 3. What about point smoothing? + + When point smoothing is enabled, a triangle fan could be rendered + to approximate a circular point. This could be problematic to + define and implement so POINT_SMOOTH is ignored when drawing sprite + points. + + Smoothed points can be approximated by using an appropriate texture + images, alpha testing and blending. + + POLYGON_SMOOTH does effect the rendering of the quadrilateral, however. + + 4. What about sprite rotation? + + There is none. Sprite points are always rendered as window-aligned + squares. One could define rotated texture images if desired. A 3D + texture and appropriate texture r coordinates could be used to + effectively specify image rotation per point. + + 5. What about POLYGON_MODE? + + POLYGON_MODE does not effect the rasterization of the quadrilateral. + + 6. What about POLYGON_CULL? + + TBD. Polygon culling is normally specified and implemented in the + transformation stage of OpenGL. However, some rasterization hardware + implements it later during triangle setup. + + Polygon culling wouldn't be useful for sprite points since the + quadrilaterals are always defined in counter-clockwise order in + window space. For that reason, polygon culling should probably be + ignored. + + 7. Should sprite points be alpha-attenuated if their size is below the + point parameter's threshold size? + + 8. Should there be an advertisized maximum sprite point size? + + No. Since we're rendering the point as a quadrilateral there's no + need to limit the size. + + +New Procedures and Functions + + None. + +New Tokens + + Accepted by the <pname> parameter of Enable, Disable, IsEnabled, + GetIntegerv, GetBooleanv, GetFloatv and GetDoublev: + + SPRITE_POINT_MESA 0x???? + MAX_SPRITE_POINT_SIZE_MESA 0x????

If the four vertices of the quadrilateral + are labeled A, B, C, and D, starting at the lower-left corner and moving + counter-clockwise around the quadrilateral, then the vertex and + texture coordinates are computed as follows: + + vertex window coordinate texture coordinate + A (x-r, y-r, z, w) (0, 0, r, q) + B (x+r, y-r, z, w) (1, 0, r, q) + C (x+r, y+r, z, w) (1, 1, r, q) + D (x-r, y+r, z, w) (0, 1, r, q) + + where x, y, z, w are the point's window coordinates, r and q are the + point's 3rd and 4th texture coordinates and r is half the point's + size. The other vertex attributes (such as the color and fog coordinate) + are simply duplicated from the original point vertex. + + Point size may either be specified with PointSize or computed + according to the EXT_point_parameters extension. + + The new texture coordinates are not effected by texgen or the texture + matrix. Note, however, that the texture r and q coordinates are passed + unchanged and may have been computed with texgen and/or the texture + matrix. + + If multiple texture units are present the same texture coordinate is + used for all texture units. + + The point is then rendered as if it were a quadrilateral using the + normal point sampling rules.

The set of calls and the + amount of static data that is logged can be controlled at runtime. + The application can add comments and enable or disable tracing of GL + operations at any time.

The current implementation + in Mesa is covered by Mesa's XFree86-style copyright by the authors above. + This extension is partially inspired by the Quake2 QGL wrapper. + +Issues + + + (1) Is this Extension obsolete because it can + be implemented as a wrapper DLL? + + RESOLVED: No. While certain operating systems (Win32) provide linkers + that facilitate this kind of solution, other operating systems + (Linux) do not support hierarchical linking, so a wrapper solution + would result in symbol collisions. + Further, IHV's might have builtin support for tracing GL execution + that enjoys privileged access, or that they do not wish to separate + the tracing code from their driver code base. + + (2) Should the Trace API explicitely support the notion of "frames? + This would require hooking into glXSwapBuffers calls as well. + + RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA + and TraceComment along with external parsing tools to split the + trace into frames, in whatever way considered adequate. + + (2a) Should GLX calls be traced? + + PBuffers and other render-to-texture solutions demonstrate that + context level commands beyond SwapBuffers might have to be + traced. The GL DLL exports the entry points, so this would not + be out of the question. + + (3) Should the specification mandate the actual output format? + + RESOLVED: No. It is sufficient to guarantee that all data and commands + will be traced as requested by Enable/DisableTraceMESA, in the order + encountered. Whether the resulting trace is available as a readable + text file, binary metafile, compilable source code, much less which + indentation and formatting has been used, is up to the implementation. + For the same reason this specification does not enforce or prohibit + additional information added to the trace (statistics, profiling/timing, + warnings on possible error conditions). + + (4) Should the comment strings associated with names and pointer (ranges) + be considered persistent state? + + RESOLVED: No. The implementation is not forced to use this information + on subsequent occurences of name/pointer, and is free to consider it + transient state. + + (5) Should comment commands be prohibited between Begin/End? + + RESOLVED: Yes, with the exception of TraceCommentMESA.

The primary intention of tracing is to aid in program + debugging. + + A trace is started with the command + + void NewTraceMESA( bitfield mask, const GLubyte * traceName ) + + <mask> may be any value accepted by PushAttrib and specifies a set of + attribute groups. The state values included in those attribute groups + is written to the trace as a sequence of GL commands. + + <traceName> specifies a name or label for the trace.

The special token TRACE_ALL_BITS_MESA + indicates all classes of commands are to be logged. + + TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of + Begin/End, including Begin/End. + + TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of + Begin/End, including Begin/End. + + TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer, + ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands. + + TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by + TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and + TexSubImage3D commands. + + TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by + Bitmap and DrawPixels commands. + + TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is + set, GetError will be executed whereever applicable, and the result will + be added to the trace as a comment. The error returns are cached and + returned to the application on its GetError calls. If the user does not + wish the additional GetError calls to be performed, this bit should not + be set. + + The command + + void TraceCommentMESA( const ubyte* comment ) + + immediately adds the <comment> string to the trace output, surrounded + by C-style comment delimiters. + + The commands + + void TraceTextureMESA( uint name, const ubyte* comment ) + void TraceListMESA( uint name, const ubyte* comment ) + + associates <comment> with the texture object or display list specified + by <name>. Logged commands which reference the named texture object or + display list will be annotated with <comment>. If IsTexture(name) or + IsList(name) fail (respectively) the command is quietly ignored. + + The commands + + void TracePointerMESA( void* pointer, const ubyte* comment ) + + void TracePointerRangeMESA( const void* first, + const void* last, + const ubyte* comment ) + + associate <comment> with the address specified by <pointer> or with + a range of addresses specified by <first> through <last>. + Any logged commands which reference <pointer> or an address between + <first> and <last> will be annotated with <comment>. + + The command + + void TraceAssertAttribMESA( bitfield attribMask ) + + will add GL state queries and assertion statements to the log to + confirm that the current state at the time TraceAssertAttrib is + executed matches the current state when the trace log is executed + in the future. + + <attribMask> is any value accepted by PushAttrib and specifies + the groups of state variables which are to be asserted. + + The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA, + TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA, + TracePointerMESA and TracePointerRangeMESA are not compiled into display lists. + + + Examples: + + The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state + variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE + to get the values <test>, <func>, <mask>, and <clear> respectively. + Statements equivalent to the following will then be logged: + + glEnable(GL_DEPTH_TEST); (if <test> is true) + glDisable(GL_DEPTH_TEST); (if <test> is false) + glDepthFunc(<func>); + glDepthMask(<mask>); + glClearDepth(<clear>); + + + The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state + variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE + to get the values <test>, <func>, <mask>, and <clear> respectively. + The resulting trace might then look will like this: + + { + GLboolean b; + GLint i; + GLfloat f; + b = glIsEnabled(GL_DEPTH_TEST); + assert(b == <test>); + glGetIntegerv(GL_DEPTH_FUNC, &i); + assert(i == <func>); + glGetIntegerv(GL_DEPTH_MASK, &i); + assert(i == <mask>); + glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f); + assert(f == <clear>); + } + + +Additions to Chapter 6 of the OpenGL 1.2.1 Specification + (State and State Requests) + + Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or + GetDoublev returns the current command class trace mask. + + Querying TRACE_NAME_MESA with GetString returns the current trace name. + + +Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance) + + The MESA_trace extension can be used in a way that does not affect data + flow from application to OpenGL, as well as data flow from OpenGL to + application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA + will add additional GetError queries. Setting a trace mask with NewTraceMESA + as well as use of TraceAssertAttribMESA might cause additional state queries. + With the possible exception of performance, OpenGL rendering should not be + affected at all by a properly chosen logging operation. + +Additions to the AGL/GLX/WGL Specifications + + None. + +GLX Protocol + + None.

Basic Usage</h2> + +<p> +The autoconf generated configure script can be used to guess your +platform and change various options for building Mesa. To use the +configure script, type: +</p> + +<pre> + ./configure +</pre> + +<p> +To see a short description of all the options, type <code>./configure +--help</code>. If you are using a development snapshot and the configure +script does not exist, type <code>./autogen.sh</code> to generate it +first. If you know the options you want to pass to +<code>configure</code>, you can pass them to <code>autogen.sh</code>. It +will run <code>configure</code> with these options after it is +generated. Once you have run <code>configure</code> and set the options +to your preference, type: +</p> + +<pre> + make +</pre> + +<p> +This will produce libGL.so and several other libraries depending on the +options you have chosen. Later, if you want to rebuild for a different +configuration run <code>make realclean</code> before rebuilding. +</p> + +<p> +Some of the generic autoconf options are used with Mesa: + +<ul> +<li><code>--prefix=PREFIX</code> - This is the root directory where +files will be installed by <code>make install</code>. The default is +<code>/usr/local</code>. +</li> +<li><code>--exec-prefix=EPREFIX</code> - This is the root directory +where architecture-dependent files will be installed. In Mesa, this is +only used to derive the directory for the libraries. The default is +<code>${prefix}</code>. +</li> +<li><code>--libdir=LIBDIR</code> - This option specifies the directory +where the GL libraries will be installed. The default is +<code>${exec_prefix}/lib</code>. It also serves as the name of the +library staging area in the source tree. For instance, if the option +<code>--libdir=/usr/local/lib64</code> is used, the libraries will be +created in a <code>lib64</code> directory at the top of the Mesa source +tree. +</li> +<li><code>--enable-static, --disable-shared</code> - By default, Mesa +will build shared libraries. Either of these options will force static +libraries to be built. It is not currently possible to build static and +shared libraries in a single pass. +</li> +<li><code>CC, CFLAGS, CXX, CXXFLAGS</code> - These environment variables +control the C and C++ compilers used during the build. By default, +<code>gcc</code> and <code>g++</code> are used with the options +<code>"-g -O2"</code>. +</li> +<li><code>LDFLAGS</code> - An environment variable specifying flags to +pass when linking programs. These are normally empty, but can be used +to direct the linker to use libraries in nonstandard directories. For +example, <code>LDFLAGS="-L/usr/X11R6/lib"</code>. +</li> +<li><code>PKG_CONFIG_PATH</code> - When available, the +<code>pkg-config</code> utility is used to search for external libraries +on the system. This environment variable is used to control the search +path for <code>pkg-config</code>. For instance, setting +<code>PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig</code> will search for +package metadata in <code>/usr/X11R6</code> before the standard +directories. +</li> +</ul> +</p> + +<p> +There are also a few general options for altering the Mesa build: +<ul> +<li><code>--with-x</code> - When the X11 development libraries are +needed, the <code>pkg-config</code> utility <a href="#pkg-config">will +be used</a> for locating them. If they cannot be found through +<code>pkg-config</code> a fallback routing using <code>imake</code> will +be used. In this case, the <code>--with-x</code>, +<code>--x-includes</code> and <code>--x-libraries</code> options can +control the use of X for Mesa. +</li> +<li><code>--enable-gl-osmesa</code> - The <a href="osmesa.html">OSMesa +library</a> can be built on top of libGL for drivers that provide it. +This option controls whether to build libOSMesa. By default, this is +enabled for the Xlib driver and disabled otherwise. Note that this +option is different than using OSMesa as the driver. +</li> +<li><code>--enable-debug</code> - This option will enable compiler +options and macros to aid in debugging the Mesa libraries. +</li> +<li><code>--disable-asm</code> - There are assembly routines +available for a few architectures. These will be used by default if +one of these architectures is detected. This option ensures that +assembly will not be used. +</li> +<li><code>--enable-32-bit, --enable-64-bit</code> - By default, the +build will compile code as directed by the environment variables +<code>CC</code>, <code>CFLAGS</code>, etc. If the compiler is +<code>gcc</code>, these options offer a helper to add the compiler flags +to force 32- or 64-bit code generation as used on the x86 and x86_64 +architectures. +</li> +</ul> +</p> + + +<a name="driver"> +<h2>2. Driver Options</h2> + +<p> +There are several different driver modes that Mesa can use. These are +described in more detail in the <a href="install.html">basic +installation instructions</a>. The Mesa driver is controlled through the +configure option --with-driver. There are currently three supported +options in the configure script. +</p> + +<ul> + +<a name="xlib"> +<li><b><em>Xlib</em></b> - This is the default mode for building Mesa. +It uses Xlib as a software renderer to do all rendering. It corresponds +to the option <code>--with-driver=xlib</code>. The libX11 and libXext +libraries, as well as the X11 development headers, will be need to +support the Xlib driver. +</li> + +<a name="dri"> +<li><b><em>DRI</em></b> - This mode uses the DRI hardware drivers for +accelerated OpenGL rendering. Enable the DRI drivers with the option +<code>--with-driver=dri</code>. See the <a href="install.html">basic +installation instructions</a> for details on prerequisites for the DRI +drivers. +</li> + +<!-- DRI specific options --> +<p> +<ul> +<li><code>--with-dri-driverdir=DIR</code> - This option specifies the +location the DRI drivers will be installed to and the location libGL +will search for DRI drivers. The default is <code>${libdir}/dri</code>. +</li> +<li><code>--with-dri-drivers=DRIVER,DRIVER,...</code> - This option +allows a specific set of DRI drivers to be built. For example, +<code>--with-dri-drivers="swrast,i965,radeon,nouveau"</code>. By +default, the drivers will be chosen depending on the target platform. +See the directory <code>src/mesa/drivers/dri</code> in the source tree +for available drivers. Beware that the swrast DRI driver is used by both +libGL and the X.Org xserver GLX module to do software rendering, so you +may run into problems if it is not available.</li> +<!-- This explanation might be totally bogus. Kristian? --> +<li><code>--disable-driglx-direct</code> - Disable direct rendering in +GLX. Normally, direct hardware rendering through the DRI drivers and +indirect software rendering are enabled in GLX. This option disables +direct rendering entirely. It can be useful on architectures where +kernel DRM modules are not available. +</li> +<li><code>--enable-glx-tls</code> - Enable Thread Local Storage (TLS) in +GLX. +</li> +<li><code>--with-expat=DIR</code> - The DRI-enabled libGL uses expat to +parse the DRI configuration files in <code>/etc/drirc</code> and +<code>~/.drirc</code>. This option allows a specific expat installation +to be used. For example, <code>--with-expat=/usr/local</code> will +search for expat headers and libraries in <code>/usr/local/include</code> +and <code>/usr/local/lib</code>, respectively. +</li> +</ul> +</p> + +<a name="osmesa"> +<li><b><em>OSMesa</em></b> - No libGL is built in this +mode. Instead, the driver code is built into the Off-Screen Mesa +(OSMesa) library. See the <a href="osmesa.html">Off-Screen Rendering</a> +page for more details. +</li> + +<!-- OSMesa specific options --> +<p> +<ul> +<li><code>--with-osmesa-bits=BITS</code> - This option allows the size +of the color channel in bits to be specified. By default, an 8-bit +channel will be used, and the driver will be named libOSMesa. Other +options are 16- and 32-bit color channels, which will add the bit size +to the library name. For example, <code>--with-osmesa-bits=16</code> +will create the libOSMesa16 library with a 16-bit color channel. +</li> +</ul> +</p> + +</ul> + + +<a name="library"> +<h2>3. Library Options</h2> + +<p> +The configure script provides more fine grained control over the GL +libraries that will be built. More details on the specific GL libraries +can be found in the <a href="install.html">basic installation +instructions</a>. + +<ul> +<a name="glu"> +<li><b><em>GLU</em></b> - The libGLU library will be built by default +on all drivers. This can be disable with the option +<code>--disable-glu</code>. +</li> + +<a name="glw"> +<li><b><em>GLw</em></b> - The libGLw library will be built by default +if libGLU has been enabled. This can be disable with the option +<code>--disable-glw</code>. +</li> + +<a name="glut"> +<li><b><em>GLUT</em></b> - The libglut library will be built by default +if libGLU has been enabled and the glut source code from the MesaGLUT +tarball is available. This can be disable with the option +<code>--disable-glut</code>. +</li> +</ul> +</p> + + +<a name="demos"> +<h2>4. Demo Program Options</h2> + +<p> +There are many demonstration programs in the MesaDemos tarball. If the +programs are available when <code>./configure</code> is run, a subset of +the programs will be built depending on the driver and library options +chosen. See the directory <code>progs</code> for the full set of demos. + +<ul> +<li><code>--with-demos=DEMOS,DEMOS,...</code> - This option allows a +specific set of demo programs to be built. For example, +<code>--with-demos="xdemos,slang"</code>. Beware that if this option is +used, it will not be ensured that the necessary GL libraries will be +available. +</li> +<li><code>--without-demos</code> - This completely disables building the +demo programs. It is equivalent to <code>--with-demos=no</code>. +</li> +</ul> +</p> + +</body> +</html> diff --git a/dist/Mesa/docs/cell.html b/dist/Mesa/docs/cell.html new file mode 100644 index

across the SPUs in a tiled-based manner. +Batches of transformed triangles are sent to the SPUs (actually, pulled by from +main memory by the SPUs). +Each SPU loops over a set of 32x32-pixel screen tiles, rendering the triangles +into each tile. +Because of the limited SPU memory, framebuffer tiles are paged in/out of +SPU local store as needed. +Similarly, textures are tiled and brought into local store as needed. +</p> + + +<H2>Status</H2> + +<p> +As of September 2008, the driver supports smooth/flat shaded triangle rendering +with Z testing and simple texture mapping. +Simple demos like gears run successfully. +To test texture mapping, try progs/demos/texcyl (press right mouse button for +rendering options). +</p> +<p> +Runtime/dynamic code generation is being done for per-fragment +operations (Z test, blend, etc) and for fragment programs (though only a +few opcodes are implemented now). +</p> +<p> +In general, however, the driver is rather slow because all vertex +transformation is being done by an interpreter running on the PPU. +Programs with many vertices or complex vertex shaders will run especially +slow. +This will be addressed in the future. +</p> + + + +<H2>Debug Options</H2> + +<p> +The CELL_DEBUG env var can be set to a comma-separated list of one or +more of the following debug options: +</p> +<ul> +<li><b>checker</b> - use a different background clear color for each SPU. + This lets you see which SPU is rendering which screen tiles. +<li><b>sync</b> - wait/synchronize after each DMA transfer +</ul> + +<p> +If the GALLIUM_NOCELL env var is set, the softpipe driver will be used +intead of the Cell driver. +This is useful for comparison/validation. +</p> + + + +<H2>Contributing</H2> + +<p> +If you're interested in contributing to the

In particular the color buffer memory will be allocated + at a location in VRAM (and in a suitable format) which can be displayed + by the graphics hardware. + + Note that the width and height of the screen surface need not exactly + match the monitor's current resolution. For example, while the monitor + may be configured to to show 1024x768 pixels, the associated screen + surface may be larger, such as 1200x1000. The "screen origin" attribute + will specify which region of the screen surface which is visible on the + monitor. The screen surface can be scrolled by changing this origin. + + This extension also defines functions for controlling the monitor's + display mode (width, height, refresh rate, etc), and specifing which + screen surface is to be displayed on a monitor. + + The new EGLModeMESA type and related functions are very similar to the + EGLConfig type and related functions. The user may get a list of + supported modes for a screen and specify the mode to be used when + displaying a screen surface. + + +Issues + + 1. Should EGL_INTERLACE be a supported mode attribute? + + Arguments against: + + No, this should be provided by another extension which would + also provide the mechanisms needed to play back interlaced video + material correctly on hardware that supports it. + This extension should prefer non-interlaced modes. [M. Danzer] + + Arguments for: + + An interlaced display can be of use without considering video + material. Being able to query whether a screen is operating in + interlaced mode can be used by applications to control their + drawing. For example: avoid drawing 1-pixel-wide horizontal lines + if screen is interlaced. [B. Paul] + + Resolution: Defer for future extension? + + + 2. Should EGL_REFRESH_RATE be a supported mode attribute? + + Arguments for: + + Yes, it's been shown that applications and/or users need to select + modes by this. [M. Danzer] + + Many examples have been given in which it's desirable to let the + user choose from a variety of refresh rates without having to + restart/reconfigure. [B. Paul] + + Arguments against: + + TBD. + + Resolution: Yes. + + + 3. Exactly how should the list of modes returned by eglChooseConfigMESA + be sorted? + + Current method is described in the text below. Subject to change. + + Alternately, leave the sorting order undefined so that each + implementation can return the modes in order of "most desirable" + to "least desirable" which may depend on the display technology + (CRT vs LCD, etc) or other factors. + + + 4. How should screen blanking be supported? Note that a screen can be + disabled or turned off by calling eglShowSurface(dpy, scrn, + EGL_NO_SURFACE, EGL_NO_MODE_MESA). But what about power-save mode? + + I would defer this to other extensions that depend on this one. + I can imagine people wanting different semantics not just in + relation to the power management API being exposed (DPMS or whatever) + but also relating to what events can trigger EGL_CONTEXT_LOST. Also + I'm not sure whether power management commands are properly operations + on the Display or on a screen surface. [A. Jackson] + + + 5. Should the EGL_PHYSICAL_SIZE_EGL query be kept? The size information + isn't always reliable (consider video projectors) but can still be + used to determine the pixel aspect ratio. + + Resolution: Omit. The EGL 1.2 specification includes queries for + the display resolution and pixel aspect ratio. + + + 6. Should detailed mode timing information be exposed by this API? + + Probably not. Instead, offer that information in a layered extension. + + + 7. How should the notion of a screen's "native" mode be expressed? + For example, LCD panels have a native resolution and refresh rate + that looks best but other sub-optimal resolutions may be supported. + + The mode attribute EGL_OPTIMAL_MESA will be set for modes which + best match the screen. [M. Danzer] + + + 8. Should eglQueryModeStringMESA() be included? This function returns + a human-readable string which corresponds to an EGLMode. + + Arguments for: + + A mode name such as "HDTV-720P" might mean more to users than + "1280x720@60Hz" if the later were generated via code. + + Arguments against: + + There's no standard syntax for the strings. May cause more + trouble than it's worth. + + Postpone for future extension. [A. Jackson] + + Latest discussion leaning toward omitting this function. + + + 9. Should we use "Get" or "Query" for functions which return state? + The EGL 1.x specification doesn't seem to be totally consistent + in this regard, but "Query" is used more often. + + Use "Get" for mode-related queries (as for EGLConfigs) but "Query" + for everything else. + + + 10. What should be the default size for screen surfaces? + + For Pbuffer surfaces the default width and height are zero. + We'll do the same for screen surfaces. Since there's no function + to resize surfaces it's useless to have a 0x0 screen, but this isn't + a situation that'll normally be encountered. + + + 11. Should there be a function for resizing a screen surface? + + Suppose one wants to change the screen's size in the EGL application. + Also suppose there's a hardware restriction such that only one screen + surface can exist at a time (either for lack of memory or because of + memory layout restrictions). + + The basic idea is that the currently displayed screen surface must + be deallocated before a new one can be created. Perhaps a resize + function would work better? + + + 12. How should sub-pixel LCD color information be made available? + What about the display's gamma value? + + Perhaps expose as additional read-only mode attributes. + + Perhaps postpone for a layered extension. + + + 13. What happens if the user attempts to delete a screen surface that + is currently being shown? + + Spec currently says that's illegal and that an error (TBD) will be + generated. + + + 14. What if the physical screen size can't be determined? Should + a query of EGL_PHYSICAL_SIZE_MESA return [0,0]? + + Obsolete: EGL_PHYSICAL_SIZE_MESA not used. + + + 15. Suppose the device's number of RAMDACs is different from the + number of output ports. For example, a graphics card with + two RAMDACs but three ports (VGA, DVI, TV). + + Address this in a follow-on extension. [Matthias Hopf] + + + 16. How should we deal with on-the-fly device changes? For example, + the monitor being unplugged and replaced by another with different + characteristics? + + A HAL event could be received via DBUS in the application [J. Smirl, + A. Jackson]. + + Should there be an EGL mechanism for detecting this? Maybe an + EGL_SCREEN_LOST error (similar to EGL_CONTEXT_LOST) can be recorded + when there's a screen change. At least then the application can + poll to detect this situation. + + Maybe leave that to a future extension. + + See also the EGL_SCREEN_COUNT_MESA query. + + + 17. What if pixel-accurate panning is not supported (see + eglScreenPositionMESA)? [M. Danzer] + + Is this a common problem? Can we ignore it for now? + + + 18.

The \c fb_format specifies which color components are in + * each pixel and what the default order is. For example, \c GL_RGB specifies + * that red, green, blue are available and red is in the "most significant" + * position and blue is in the "least significant". The \c fb_type specifies + * the bit sizes of each component and the actual ordering. For example, if + * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11] + * are the blue value, bits [10:5] are the green value, and bits [4:0] are + * the red value. + * + * One sublte issue is the combination of \c GL_RGB or \c GL_BGR and either + * of the \c GL_UNSIGNED_INT_8_8_8_8 modes. The resulting mask values in the + * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or + * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as + * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8 + * still uses 32-bits. + * + * If in doubt, look at the tables used in the function. + * + * \param ptr_to_modes Pointer to a pointer to a linked list of + * \c __GLcontextModes. Upon completion, a pointer to + * the next element to be process will be stored here. + * If the function fails and returns \c GL_FALSE, this + * value will be unmodified, but some elements in the + * linked list may be modified. + * \param fb_format Format of the framebuffer. Currently only \c GL_RGB, + * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported. + * \param fb_type Type of the pixels in the framebuffer. Currently only + * \c GL_UNSIGNED_SHORT_5_6_5, + * \c GL_UNSIGNED_SHORT_5_6_5_REV, + * \c GL_UNSIGNED_INT_8_8_8_8, and + * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported. + * \param depth_bits Array of depth buffer sizes to be exposed. + * \param stencil_bits Array of stencil buffer sizes to be exposed. + * \param num_depth_stencil_bits Number of entries in both \c depth_bits and + * \c stencil_bits. + * \param db_modes Array of buffer swap modes. If an element has a + * value of \c GLX_NONE, then it represents a + * single-buffered mode. Other valid values are + * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and + * \c GLX_SWAP_UNDEFINED_OML. See the + * GLX_OML_swap_method extension spec for more details. + * \param num_db_modes Number of entries in \c db_modes. + * \param visType GLX visual type. Usually either \c GLX_TRUE_COLOR or + * \c GLX_DIRECT_COLOR. + * + * \returns + * \c GL_TRUE on success or \c GL_FALSE on failure.
