◆ VisibilityTest()

bool vtkSurfaceLICHelper::VisibilityTest ( double  ndcBBox[24])

given a axes aligned bounding box in normalized device coordinates test for view frustum visibility.

if all points are outside one of the view frustum planes then this box is not visible. we might have false positive where more than one clip plane intersects the box.
