I know that the computedRotationMatix is calculated multiplying PreRotation * Rotation * PostRotation;
computedRotationMatix = PreRotation * Rotation * PostRotation;
But currently i only knows the computedRotationMatix , PreRotation , PostRotation;
How can i find the Rotation matrix?
Thanks for your time
Matrix calculation
Provided that PreRotation and PostRotation are invertible,
Rotation = PreRotation[sup]-1[/sup] * computedRotationMatrix * PostRotation[sup]-1[/sup]
Rotation = PreRotation[sup]-1[/sup] * computedRotationMatrix * PostRotation[sup]-1[/sup]
And provided they are rotations, you can transpose them instead of finding their inverses, since the results should match.
