Say I have a Rotation Matrix, which is used to rotate a 3D model.
Is it possible to set the yaw of the rotation matrix to zero before applying it to the model?
Regards, Adam.
RotMatrix=R(yaw)*R(pitch)*R(roll)
to eliminate yaw factor, we can left-multiply this matrix on negative yaw matrix
RotMatrixNew=R(-yaw)*R(yaw)*R(pitch)*R(roll) = I**R*(pitch)*R(roll) = R(pitch)*R(roll)
If yaw angle isn’t known before, then it could be calculated as
yaw = ArcTan2(RotMatrix[2][1], RotMatrix[1][1])
