Detailed Description

Describes a geometric transformation.

A transform contains translation and rotation. It is used to represent the position and orientation of rigid frames.

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.
