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
virtual void csOrthoTransform::SetO2T | ( | const csMatrix3 & | m | ) | [inline, virtual] |
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 661 of file transfrm.h.
virtual void csOrthoTransform::SetT2O | ( | const csMatrix3 & | m | ) | [inline, virtual] |
Set 'this' to 'other' transformation matrix.
This is equivalent to SetO2T() except that you can now give the inverse matrix.
Reimplemented from csReversibleTransform.
