WebJan 7, 2016 · Ray Marching 101 – Part 1. // Ray Marching is a technique that is very similar to Ray Tracing. // with any geometry. Both techniques require that geometry in the scene. // be defined using mathematical formulas. However the techniques differ. // in how the geometry is defined mathematically. As for ray tracing, WebSuppose we want to render a simple sphere. A naive way to do ray marching would be to simply choose a small delta and for each ray from the camera, advance the ray by this small amount until it crosses over into the "inside of the sphere". Here, we can define a Boolean "inside" function as simply (r^2 < 1).
