<hr><a name="_details"></a><h2>Detailed Description</h2>
A class which defines a reversible transformation from one coordinate system to another by maintaining an inverse transformation matrix.
<p>
This is a variant which only works on orthonormal transformations (like the camera transformation) and is consequently much more optimal.
