shapes::Mesh Class Reference

Definition of a triangle mesh By convention the "center" of the shape is at the origin. For a mesh this implies that the AABB of the mesh is centered at the origin. Some methods may not work with arbitrary meshes whose AABB is not centered at the origin. More...

Detailed Description

Definition of a triangle mesh By convention the "center" of the shape is at the origin. For a mesh this implies that the AABB of the mesh is centered at the origin. Some methods may not work with arbitrary meshes whose AABB is not centered at the origin.
