Hi, blendEquation $= ... has no effect on my system, ghc 6.4.1/6.4.2 with this GL implementation: OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce 6600 GT/PCI/SSE2/3DNOW! OpenGL version string: 2.0.2 NVIDIA 87.56 It works from C though. By the way, it would be so great to have GLSL support in HOpenGL. Any chance to see it soon? Thanks, Gunnar.

What platform are you using? Does the BlendEqn example from http://darcs.haskell.org/packages/GLUT/examples/RedBook/BlendEqn.hs work? Is blending enabled at all? (blend $= Enabled) A short example program demonstrating the problem might help, too.

The "Yellow Book" is already on my desk... :-) I definitely intend to support GLSL in the OpenGL package, but if soon means "in the next few weeks", then the answer is "no". The GLSL API is not that small, so the implementation will very probably be done in a few iterations. Cheers, S.

I only wrote such an example in C, which worked. Had I done this in Haskell too I would have noticed that blending was indeed disabled. Sorry for the false alarm. The BlendEqn example works.

That's great. Thanks, Gunnar.
