Some OpenGL Projects

Jan 7, 2023, 2:50 p.m.

GL rendering demo screenshot I have been working on some OpenGL projects lately. One is a setup tutorial for Macs for Xcode using glfw and glew. The setup is always a bit fiddly to me and has changed since the last time I went through it, so I created a separate GitHub repo for just the setup part and a small spinning triangle. It's available at

The second project is more interesting. I just wanted to get a relatively decent rendering setup going with some actual mesh models. I reused the SMF reading code from some grad school projects to load a few more interesting objects, and also coded in mesh generation for cubes, spheres, and pyramids. It uses Blinn-Phong shading and texture mapping. Several of the textures are generated procedurally using Perlin noise or a checkers pattern and several are loaded from PNG files. The libpng loading code is self-contained and probably useful to others.

When I have some time to return to this I would like to add shadows and environment mapping of some kind to make it more complete. You can check out the code and screenshot at

I finally got around to sharing the game I created with my kids a few years ago. It's a simple space invaders style game written in Python with Pygame Zero to help them learn about coding. We also used PyInstaller to create a distributable version. The binaries are in at for Mac and PC, and the source code is on GitHub at I also put the lessons I wrote for them on programming, Linux, and Python up in a separate GitHub repo, Hopefully these are useful to other beginners.

Jun 5, 2022, 11 a.m.

I started a site recently to play around with Ghost CMS a bit, and for something of interest content wise I decided to make it about philosophy and inspirational quotes.
