WebApr 30, 2024 · 1. When drawing in OpenGL and related APIs you usually have one or more models. In your case, this would be the cylinder and the icosahedron. The models are generally generated at some default size which may or may not suit your needs for a particular task. You move them, scale them, and rotate them by setting up a model … WebSample Code References. The following code samples have been found which appear to reference the functions described here. Take care that the code may be old, broken or not even use PyOpenGL.
