[Mesa3d-dev] [RFC] MESA_texture_env_combine2 extension

[Holger W. <hwa...@ya...>]

Hi everybody,

I attached a preliminary spec for a MESA_texture_env_combine2 extension,
which adds some new modes including dot3 modes for perpixel lighting on
top of EXT_texture_env_combine.

Now I'd like to get some comments from people who have access to hardware 
specs (and from those who have to use the extension ...). Modes, which
don't map on any known card make no sense.

In the mesa_3_3_texture_env_combine2 branch a experimental implementation
of the extension is available via CVS. A perpixel demo, which does
ambient, diffuse and specular lighting using the new modes in 2 passes and
one CopyPixels call (for specular color lookup) is included. Some
screenshots and the demo source you find at

    http://www.informatik.hu-berlin.de/~waechtle/mesa

However, to get it working, you have to check out the
MESA_texture_env_combine2 branch.
