Mesh.Optimize
Optimize(): void;
void Optimize();
def Optimize() as void
Description

Optimizes the mesh for display.

This operation might take a while but will make the geometry displayed be faster. You should use it if you generate a mesh from scratch procedurally and you want to trade better runtime performance against higher load time. Internally it optimizes the triangles for vertex cache locality. For imported models you should never call this as the import pipeline already does it for you.
