Here is the matrix: [url=http://en.wikipedia.org/wiki/Rotation_matrix]Rotation Matrix[/url] Gonna use the M(vector, theta) version. The second one, the one to rotate about an arbitrary unit vector. The problem I'm having is writing it out long-hand in code. Ah... gonna substitue @ for theta. x' = cos@+(1-cos@)x^2 + (1-cos@)yx+(sin@)z + (1-cos@)zx-(sin@)y Is that right for x', or do I still have to mult all parts by x? Loading...
