implicit function for a bounding box
vtkBox computes the implicit function and/or gradient for a axis-aligned bounding box. (The superclasses transform can be used to modify this orientation.) Each side of the box is orthogonal to all other sides meeting along shared edges and all faces are orthogonal to the x-y-z coordinate axes. (If you wish to orient this box differently, recall that the superclass vtkImplicitFunction supports a transformation matrix.) vtkCube is a concrete implementation of vtkImplicitFunction.

Intersect a line with the box. Give the endpoints of the line in p1 and p2. The parameteric distances from p1 to the entry and exit points are returned in t1 and t2, where t1 and t2 are clamped to the range [0,1]. The entry and exit planes are returned in plane1 and plane2 where integers (0, 1, 2, 3, 4, 5) stand for the (xmin, xmax, ymin, ymax, zmin, zmax) planes respectively, and a value of -1 means that no intersection occurred. The actual intersection coordinates are stored in x1 and x2, which can be set to NULL of you do not need them to be returned. The function return value will be zero if the line is wholly outside of the box.
