Ray marching tianchen
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. http://adrianb.io/2016/10/01/raymarching.html
