Hi, So I'm trying to get a certain sort of 3D terrain working in PyOpenGL. The idea is to get vertex buffer objects to draw a simple 2D plane comprised of many flat polygons, and use a vertex shader to deform that with a heightmap and map that on a sphere. I've managed to do this with a grid

Hi I'm using npfile which is giving me a deprecation warning. For the time being I want to continue using it but I would like to suppress the warning messages. Is it possible to trap the deprecation warning but still have the npfile go ahead? Thanks Brennan
