perform various plane computations
vtkPlane provides methods for various plane computations. These include projecting points onto a plane, evaluating the plane equation, and returning plane normal. vtkPlane is a concrete implementation of the abstract class vtkImplicitFunction.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Return the distance of a point x to a plane defined by n(x-p0) = 0. The normal n[3] must be magnitude=1.

Given a line defined by the two points p1,p2; and a plane defined by the normal n and point p0, compute an intersection. The parametric coordinate along the line is returned in t, and the coordinates of intersection are returned in x. A zero is returned if the plane and line do not intersect between (0<=t<=1). If the plane and line are parallel, zero is returned and t is set to VTK_LARGE_DOUBLE.
