View Full Version : New Extensions

Looks like a few new extensions have popped up in the registry:

GL_AMD_shader_stencil_export (http://www.opengl.org/registry/specs/AMD/shader_stencil_export.txt)
GL_AMD_seamless_cubemap_per_texture (http://www.opengl.org/registry/specs/AMD/seamless_cubemap_per_texture.txt)
GLX_INTEL_swap_event (http://www.opengl.org/registry/specs/INTEL/swap_event.txt)

The first one is the most interesting, the ability to write to the stencil reference value from the fragment shader.

The stencil-extension is most useful! Great to see AMD get more serious about OpenGL.

Now i would really like to see an extension that allows to also write the blend-color (per MRT) to influence the blend-function. It should be very similar to this stencil-extension.

Anybody any idea what the new undocumented extension are about that are included with the newest AMD driver (catalyst 10.2)?

* GL_ARB_blend_func_extended – not yet documented – Increadible: an ARB extension that is not documented and even NVIDIA does not expose yet this extension…
* GL_ARB_fragment_coord_conventions: This extension provides alternative conventions for the fragment coordinate XY location available for programmable fragment processing. Also exposed by NVIDIA (see HERE).
* GL_EXT_texture_buffer_object_rgb32: not yet documented and not exposed by NVIDIA ForceWare

Well, i would hope it's this:

But it could be something like this, too:

Or something else entirely...
