I'm writing a tool to build sceneries, based on bezier-surfaces. On my computer (P2, 233MHZ, no OpenGL-card) the program runs fine, but I tested it on three other computers (with and without gl-cards) and the bezier-surface was not shown. It's always only the bez-surface that is not shown - everything else IS. Does anyone know about differences between the openGL-implementations using the glMap* command?

thanks for help,
