I don't really know what your problem is, but if you want to rotate a point in R3 around another point in R3 (not (0,0,0)), you must:

- substract center point from point which needs to be rotated

- rotate point around the origin

- add the center point to the point that has just been rotated around the origin.

Hoped that helped
