Data complexity for virtual reality: where do all the triangles go?

Screen space rendering statistics are gathered from 150 3D objects, each modeled by between 2-K and 40-K triangles. While there is wide variance by individual object, the overall trend is that the distribution of triangles by screen size is roughly exponential in the direction of small triangles. From a subjective esthetics point of view, tessellations require 10-K visible triangles per quarter million pixels covered for acceptable results.< >
