Constructor Detail

ParametricPlane

public ParametricPlane(Point basePoint,
                       Vector directionX,
                       Vector directionY,
                       Vector normal)

Parameters:

basePoint - The base point of this plane

directionX - the x direction of this plane

directionY - the y direction of this plane

normal - the normal direction of this plane

ParametricPlane

public ParametricPlane(Point basePoint,
                       Vector directionX,
                       Vector directionY)

Parameters:

basePoint - The base point of this plane
