Description copied from interface: Rotatable

Rotates this object about a given point on a specified axis. 0 corresponds to the X axis, 1 corresponds to the Y axis, and 2 corresponds to the Z axis.

Specified by:

rotate in interface Rotatable

Parameters:

axis - the axis to rotate around

theta - the radians to rotate by

point - the center point to rotate around
