Can you show me how to rotate a Point3D @ angle X around an axis at a desired Point3D?

For example, I have a Point3D p1(10,0,0);
and I would like to rotate it 45 degrees in Z axis and has to be rotate centered at (10,0,0).

Any help is appreciated.
Thanks

Hello,

Look at the RotateTransform Class.

There's an example at the bottom of the page.

like this would work?

Point3D pt = new Point3D(10, 0, 0);
RotateTransform3D myRotateTransform = new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 0, 1), 45));
Point3D ptR = myRotateTransform.Transform(pt);
