A simple path tracer is used to render an old watch. The old watch scene is (almost) the same scene as rendered using image-based lighting in my Shadertoy shader “Old watch (IBL)“.
I created a shader quine, a fragment shader without input (textures or models) that produces a copy of its own source code as its output, on Shadertoy.
An organic-looking SDF scene in a single, fully procedural, fragment shader. The scene is modelled for this specific camera viewpoint and lighting setup.
