20120416 Mesh subdivision (2012 extended edition)

Back in 2004, when I was starting to experiment with OpenGL, I had the idea of creating meshes from scratch.

And before you can blink twice, it’s gone, destroyed by the very same hands that created it. To escape from the usual demoscene non-interactive [...]
