Hi, I've just written some code which uses 'tessellate' from Graphics.Rendering.OpenGL.GLU.Tessellation and whilst it works exactly as expected on simple data sets, it gives a bus error on larger ones (not that large - e.g. 150 points). This might be a bug in my OS's glu implementation, but I'm also inclined to suspect a bug in all the peeks and pokes HOpenGL uses to handle the data for the callbacks. I don't actually use the callback data (I've set all the data to (0 :: Int) only because there is no storable instance for ()). Does anyone have a success story with this function? Has anyone used it successfully on larger polygons? Jules
