[GEM-dev] [ pd-gem-Feature Requests-2612731 ] glsl_geometry

[marius schebella]

hi matthias,
thanks for fixing the glew.cpp bug. since I have not really worked with 
geometry shaders before I have to start from scratch, and would 
appreciate some example patches, how to link the shader. is it possible 
to setup the glProgramParameteriEXT functions within Pd?
greetings from the breeding gem community in salzburg.
marius.
