Web1 de mai. de 2024 · Ray marching doesn’t necessarily speed up ray tracing with the SDF. In fact just to render a simple triangle it requires a quite complicated function that’s called multiple times per pixel. It’s much better suited to objects that don’t have a good ray intercept function, handling reflections, warping space or repeating spaces. 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.
