Detailed Description

3d space transform wrapper class

Represent 3D space transformation object, i.e. space rotation as the quaternion, origin offset and space scale.

The logic applied to some vertices set in the spaces as follows:

• 1. v = Rotate(v)
• 2. v = Scale(v)
• 3. v = Offset(v)

Could be converted to the matrix form if required.
