I'm thinking of "abusing" texture combiners to quickly work around the missing GL_FOG in TinyGL. However, before I start with that and probably run into issues, I wanted to ask about TinyGL's texture combiner support state.
1. is GL_COMBINE supported in general?
Yes. In fact, this is the only thing that's supported in the drivers. TinyGL converts legacy texenv modes into combiners before forwarding them to the driver.Quote:
2. is GL_INTERPOLATE supported?
Yes, and MorphOS 3.8 includes some fixes that previously made it misbehave in certain situations.Quote:
3. is GL_CONSTANT supported (and consequently GL_TEXTURE_ENV_COLOR)?
If this all is supported, is it supported for all 3D hardware?
Or not until OS version xyz?
It's supported for all 3D hardware that's currently supported by MorphOS/TinyGL, so R200-R500.
If you run into any issues and you're quick enough to report them, they'll get fixed for the upcoming MorphOS 3.9 bugfix release.
