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.

Web15 de jul. de 2016 · Signed Distance Functions. Signed distance functions, or SDFs for short, when passed the coordinates of a point in space, return the shortest distance between that point and some surface. The sign of the return value indicates whether the point is inside that surface or outside (hence signed distance function). Let’s look at an example.
