Method Detail

rotatesAround

public static void rotatesAround(int index,
                                 java.awt.geom.Point2D[] positions,
                                 java.awt.geom.Point2D srcVector)

Rotates the positions arround the specified center. srcVector is a vector from the origin which is transformed to (0,1) during the rotation. It specifies the angle of the transformation.
