Rotation matrix about arbitrary vector WRONG
2003-11-12 20:16

Refer to this page:

http://www.euclideanspace.com/maths/geometry/rotations/index.htm

The matrix given for rotation about a unit vector is wrong. it should be:

[ (aVx^2+c) (aVxVy+sVz) (aVxVz-sVy) ]
[ (aVxVy-sVz) (aVy^2+c) (aVyVz+sVx) ]
[ (aVxVz+sVy) (aVyVz-sVx) (aVz^2+c) ]
