Detailed Description
A class which defines a reversible transformation from one coordinate system to another by maintaining an inverse transformation matrix.This is a variant which only works on orthonormal transformations (like the camera transformation) and is consequently much more optimal.

Member Function Documentation

Set 'other' to 'this' transformation matrix. This is the 3x3 matrix M from the transform equation T=M*(O-V). Reimplemented from csReversibleTransform. Definition at line 620 of file transfrm.h. References csMatrix3::GetTranspose(), csTransform::m_o2t, and csReversibleTransform::m_t2o. |

Set 'this' to 'other' transformation matrix. This is equivalent to SetO2T() except that you can now give the inverse matrix. Reimplemented from csReversibleTransform.
