TriangleMesh Class Reference

Detailed Description

A procedurally generated flat triangle in the XY plane, centered at the origin. The surface normal points toward +Z. The apex is at the top (+Y), the base spans the bottom (-Y). UV (0.5,0) is at the apex, (0,1) at the bottom-left corner, (1,1) at the bottom-right corner.
