OpenGL examples with PyOpenGL and Pygame

The OpenGL examples are based on book "Developing Graphics Frameworks with Python and OpenGL" by Lee Stemkoski and Michael Pascale published by CRC Press in 2021.

The examples cover all the book chapters with code, 2 through 6, with some code changes and demonstrate GLSL programming using PyOpenGL. Pygame is mainly used for control, windowing, and image loading.

You find the examples in the examples folder. Just read a class description in a script and run it. Since the object-oriented approach is used, auxiliary classes are logically separated in other folders (packages).

My environment was Python 3.8 with the following packages (without specifying their dependencies here):

numpy==1.22.4
pygame==2.1.2
PyOpenGL==3.1.6
PyOpenGL-accelerate==3.1.6

The code was tested on the same machine with two operating systems, more precisely:

  • OS: Windows 11; Vendor: ATI Technologies Inc.; Renderer: AMD Radeon(TM) Graphics; OpenGL version supported: 4.6.14761 Compatibility Profile Context 21.30.44.03 30.0.13044.3001; GLSL version supported: 4.60

  • OS: Ubuntu 20.04.3 LTS; Vendor: AMD; Renderer: AMD RENOIR (DRM 3.41.0, 5.13.0-48-generic, LLVM 12.0.0); OpenGL version supported: 4.6 (Compatibility Profile) Mesa 21.2.6; GLSL version supported: 4.60

Update:

  • On Ubuntu, you may encounter the error OpenGL.error.Error: Attempt to retrieve context when no valid context. See a bug report and suggestions to resolve it: pygame/pygame#3110
