Detailed Description

Describes a geometric transformation.

A transformation contains translation and rotation. It's used to represent the location and direction of things like bodies.

Note

The default transformation is the identity transformation - the transformation which neither translates nor rotates a location.

This data structure is 16-bytes large (on at least one 64-bit platform).

Examples

Body.cpp, Shape.cpp, and WorldBody.cpp.
