Converting 3 axis vectors to a rotation matrix
- by user38858
I am trying to get a rotation matrix (in 3dsmax) from 3 vectors that form an axis (all 3 vectors are aligned by 90 degrees each other)
Somewhere I read that I could build a rotation matrix just by inserting in every row one vector at a time (source: http://renderdan.blogspot.cz/2006/05/rotation-matrix-from-axis-vectors.html)
So, I built a matrix with these example vectors
x-axis : [-0.194624,-0.23715,-0.951778]
y-axis : [-0.773012,0.634392,0]
z-axis : [-0.6038,-0.735735,0.306788]
But for some reason, if I try to convert this matrix to eulerangles, I receive this rotation: (eulerAngles 47.7284 6.12831 36.8263) ... which is totally wrong, and doesn't align to my 3 vectors at all.
I know that rotation is quite difficult to understand, may someone shed some light? :)
