Examples

Files named starting with 00 are top-level runnable examples. See their #info for descriptions.

Note that 00-Mandelbulb-vs-Menger.frag takes a long time to compile on Mesa 20 AMDGPU; 00-MandelbarDE.frag is currently broken due to missing support files; 00-Mandelbrot-3D.frag is extremely heavy and may cause your desktop session to crash.
