<LSR Transformation> Example for Model Instancing
<LSR Transformation> is used only when
- both source and destination are LSR
- source’s axes are to be transformed as necessary to align with those of the destination
The source will then be translated, rotated, and/or scaled as specified to transform it into the target spatial reference frame.
The <LSR Transformation> may be specified by a series of steps, or by a 4x4 matrix equivalent to such a series of steps.
