WebJul 15, 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. Web盗用科长大人一张图. 3. RayMarching的算法.
