I am in need of an algorithm to extract scaling and rotation factors
from a transformation matrix. I've implemented two such algorithms from
Graphics Gems II (page 322), but have only had success with the rotation
extraction algorithm (I can't get the shear/scaling algorithm to work).
Would anyone be willing to supply some C source or references? Thanks.
