In the first two weeks of September (2015) I created an app to view and run shaders of Shadertoy on my iPhone. After finishing the first version of this app I was very pleased that Pol Jeremias and Iñigo Quílez
I wrote another WebGL fragment shader on shadertoy. This shader renders a seamless space-to-surface flight in the browser using only two triangles. No textures or 3d-models are used.
Just a repost of one of my first shaders on Shadertoy. This is a simple realtime path tracer, implemented in a webgl fragment shader. The shader shows motion blur, depth of field and importance sampling.
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.
