I have some code that I have inherited which performs a 3D rotation by taking a central point a COM if you like and then determining a vector which defines a point in the system, an atom for example. Then this vector is simply rotated by theta and phi, using matrix rotations. I have the code, but I wish to have a reference to where the code came from and how it was derived.

So no references...which is what I am keen to get hold of. Now I have the code, it works, its tested and performs rotations of an object about theta and phi. However I am finding it hard to figure where this code has come from as it seems most people are performing rotations about a specific axis and this is not what the code is doing.

Many thanks

What's with the re-post? I think you should continue your discussion where you were already discussing it, here.

Thought it just flag it up again...for more ideas!
