I am integrating RAPID_Collide in a Performer application, and using a
getDCS function to get rotation Matrix(3*3). RAPID_Collide function
needs orthonormal rotation matrix to be passed as a parameter.
 But when I am checking for orthonormal property of Matrics( A matrix
is said to be Orthonormal if multiplication of original Mat and
Transpose Mat of the Mat is Identity Mat.) I am getting diagonal
elements 1.000001, 1.000004,something like this. Basically I need Mat
having Orthonormal property not Identity Mat. Is there any way to get
orthonormal rotation matrix in Performer ? Will DCS Node of Performer
gives Orthonormal Mat ? Can anyone give me any clue?
