GEM doesn't support geometry shaders at this point. It could turn out that they won't work well with the Pd/GEM environment, but there are other aspects of GL that don't work either. GL was clearly not designed to do what GEM does, so there is a lot of work to be done for each new feature added to GL. There is a lot of compromise needed to fit the latest and greatest into a framework over a decade old.

I'm not sure if GEM has support for geometry shaders yet, but how do you imagine handling the program parameters like GL_GEOMETRY_VERTICES_OUT_EXT, GL_GEOMETRY_INPUT_TYPE_EXT, and GL_GEOMETRY_OUTPUT_TYPE_EXT without some kind of extra information since these things aren't inherent to the shader code yet most geometry shaders are written for particular input and output types?
