Rotation matrices depend on the sine and cosine functions from trigonometry. Don’t worry about dredging your high school math memories, though. Check your implementation language for a Math namespace, where you will usually find the functions named sin and cos. |
The rotation will appear to be clockwise around the corresponding ...
