| 22/11/2018 | Truchet polygons in a 4.8^2 (squares and octagons) tiling, as a pixel shader: https://www.shadertoy.com/view/MlyBRG  |
| 2/11/2018 | Raytracing a "gyrobifastigium"-shaped voxel grid with analytic intersections: https://www.shadertoy.com/view/4lcBWX The gyrobifastigium is an octahedron too, but it has regular sides (4 regular triangles + 4 regular quadrangles) so it's more mathematically pleasing, of course.   |
| 29/10/2018 | Raytracing an octahedron-shaped voxel grid with analytic intersections: https://www.shadertoy.com/view/4lcfDB Regular octahedrons apparently don't tessellate, so these are irregular. But it's all about the look, right?   |
| 24/10/2018 | Here's a trick to raytrace a triangulated heightfield taking only one sample of the heightfield per visited triangle. The triangle intersection test itself is simplified too. The algorithm is similar to triangle strip rasterisation. https://www.shadertoy.com/view/XlcBRX  |
| 2/10/2018 | Some WIP procedural modelling stuff in Notch.   |
