Detailed Description
-
class
MeshOrientation Defines the facing (normal) and up vectors of a mesh instance, e.g. used to decide whether to rotate PMI text 180 degrees so it faces the camera.
Both vectors are expected to already be normalized, and are always in object (instance-local) coordinates.
A default-constructed MeshOrientation (normal == (0,0,0)) means “not set”.
