New Extensions

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


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:…1694#Post251694

But it could be something like this, too:

Or something else entirely…
