WebIf a ray doesn't hit any object, it must be stopped after a certain distance to avoid an infinite loop. Simple operations can be applied to the DE (Distance Estimation) functions to rotate, translate, scale or twist any object. Combining a DE function with a modulo operator allows to render a plane or a space filled with "infinite" objects. WebApr 5, 2024 · Raymarching is a mathematical way of rendering. It is done with distance fields (distance from a point to a primitive), constant-steps (typically used with volume rendering), and root-finders (a math approach).
