Any undersandable description of glTexEnvi (OpenGL ES 1.x)?

I've seen as many different parameters as many source codes I saw. Is there a description can be found somewhere that refers all about those parameters in details?

Solution

  • This is pretty comprehensive.

    There are also some tex-env extensions -- I think at least add and combine are supported on most GLES 1.1 hardware, and I think PowerVR cores support dot3.

    The PowerVR SGX hardware has some fine print about combine modes - be sure to read the PowerVR docs.
