WebRay Marching. If you’ve ever visited Shadertoy, you’ve probably seen ray marching in action. It’s an interesting technique that can be used to generate fully procedural environments entirely from a single fragment shader. Unfortunately, there aren’t a ton of great resources for learning these techniques. So, I wanted to create a quick ... WebMar 13, 2024 · In 2013, I created a single WebGL fragment shader on Shadertoy that renders a Wolfenstein-like level and procedurally creates all textures needed. From this experience, I knew that the grid-based level design of Wolfenstein could also be used as a fast and simple acceleration structure and that ray tracing through this structure would be very fast.
