Volumetric shadows are a technique for creating shadows in virtual environments by using a polygonal volume as the shadow, created using real-time shadow geometry in each frame more often than not, for the most accurate and thus realistic shadowing. This polygonal area then greatly simplifies the prospect of casting sub-shadows, since if a second model is partially in the shadow volume, that part must therefore be in shadow.

Typically in VR, when we model erosive forces, we think of the smoothing effect of water. We think of smooth stones, smooth edges, and smooth cavities. We don't typically think of sharp edges and triangles. That may be a mistake.
