I have made another webgl fragment shader on shadertoy: Tokyo. This shader shows an abstract, procedural, view of Tokyo by night in the rain. In this post I will write up some notes about how this shader is made.
I made another shader in Shadertoy. Two triangles are rendered using a webgl fragment shader showing an abandoned base. The scene is rendered by ray-marching a distance field and features dynamic lights, soft shadows, reflections and ambient occlusion.
Last year I read an article describing the mathematical structure of Escher’s Print Gallery. Escher’s Print Gallery (de Prentententoonstelling in Dutch) shows a man standing in an exhibition gallery, viewing a print of a seaport.
