3d rotate
Hello all , Having a set of 3D points I want to rotate them about user defined point , not only about the mid point . how it would be done ? thank you

The ending point of any rigid body is dependent on the starting point, the angle of rotation, the plane of rotation, and the center point of rotation. The information about the how much rotation around which axes and the center of rotation can all be encoded into a rotation matrix. See for examplehttp://inside.mines.edu/fs_home/gmurray/ArbitraryAxisRotation/

The information that you have available is the starting point and the angle of rotation, but you do not have any information about the plane of rotation or the center point of rotation. Until you can provide those, you cannot make the calculation.
