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.

Given two planes, one infinite and one finite, defined by the normal n and point o (infinite plane), and the second finite plane1 defined by the three points (pOrigin,px,py), compute a line of intersection (if any).
The line of intersection is defined by the return values (x0,x1). If there is no intersection, then zero is returned; otherwise non-zero. There are two variants of this method. The static function operates on the supplied function parameters; the non-static operates on this instance of vtkPlane (and its associated origin and normal).
