LUMINANCE_ALPHA_LATC2 = LUMINANCE_ALPHA_3DC, so this is easy.
Note that there is no specification for 3DC, just a few white papers
from ATI.
|
|
The encoding/decoding algorithms are shared with RGTC.
Thanks to some magic with the base format, the RGTC texstore functions work
for LATC too.
swrast passes the related piglit tests besides two things:
- The alpha channel is wrong (it's always 1), however the incorrect alpha
channel makes some other tests fail too, so I guess it's unrelated to LATC.
- Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]),
however RGTC has the same problem.
Further testing (with other of my patches) shows that hardware drivers
and softpipe work.
BTW, ETQW uses this extension.

It was only implemented in the swrast driver and probably not used by
any applications. A modern app would use a dependent/chained texture
lookup in the fragment shader.

Remove ES2, since AMD_conservative_depth is not listed in the OpenGL ES
extension registry.

this isn't c++ please don't mix declerations with code
|
|
If an extension is prefixed with '+', attempt to enable it. This
introduces symmetry with the prefix '-', which is already allowed.
|
|
* Reduce max indentation level from 7 to 3.
* Eliminate counter variables.
* Remove function append().
|
|
The extension is off by default.
First in a patchset that implements support for AMD_conservative_depth in
the compiler.

This implements the extension by choosing a different set of texture
fetch functions when the texture parameter changes.

Add a bit in struct gl_extensions for OES_standard_derivatives, and enable
the bit by default. Advertise the extension only if the bit is enabled.
Previously, OES_standard_derivatives was advertised in GLES2 contexts
if ARB_framebuffer_object was enabled.

Fixes MSVC build.

Fixes SCons build.

The extension string in GLES1 contexts always advertised
GL_OES_point_sprite. Now advertisement depends on ARB_point_sprite being
enabled.

Change all OES extension strings that depend on ARB_framebuffer_object to
instead depend on EXT_framebuffer_object.

Add GL_OES_stencil8 to ES2.
Remove the following:
GL_OES_compressed_paletted_texture : ES1
GL_OES_depth32 : ES1, ES2
GL_OES_stencil1 : ES1, ES2
GL_OES_stencil4 : ES1, ES2
Mesa advertised these extensions, but did not actually support them.

Place GL, GLES1, and GLES2 extensions in a unified extension table. This
allows one to enable, disable, and query the status of GLES1 and GLES2
extensions by name.
When tested on Intel Ironlake, this patch did not alter the extension
string [as given by glGetString(GL_EXTENSIONS)] for any API.

This gets my vote for most pointless extension of all time, I'm guessing
some driver could possibly optimise for this instead of counting it might
just get a true/false, but I'm not really sure.
need this to eventually advertise 3.3 despite its total uselessness.

We don't support it.

The new GLSL compiler doesn't support geom shaders yet so disable the
GL_ARB_geometry_shader4 extension. Undo this when geom shaders work again.
NOTE: This is a candidate for the 7.10 branch.

GL_OES_texture_3D has a GLSL counterpart. Since it is not implemented,
GL_OES_texture_3D should not be advertised.

This adds proper support for the GL_ARB_shader_stencil_export extension
to the GLSL compiler. Thanks to Ian for pointing out where I need to add things.

Change the name in the extension tracking structure to ARB (from EXT).

This is only used in the i915 driver where it provides little benefit
for very few applications that use it with fixed function TNL.

This extension was never enabled in any driver.

Another optional ARB_imaging subset extension.

This has always been optional, and not useful.
|
|
Many of the EXT_ extensions in the subset have significant code
overhead with no users. It is not a required part of GL -- though
text describing the extension is part of the core spec since 1.2, it
is always conditional on the ARB_imaging extension.

Instead of using the invalid GL_ARB_shading_language_120 extension to
determine the GLSL version, use a new ctx->Const.GLSLVersion field.
Updated the intel and r600 drivers, but untested.

NOTE: This is a candidate for the 7.9 branch (but let's wait and see if
there's any regressions).

The new GLSL compiler doesn't support it.
Advertising it prevents Unigine Heaven from working, since it attempts to
use it.
