type TVisibilitySensorInstance = class(TShapeTree)
Description
no description available, TShapeTree description follows
Tree of shapes.
Although VRML/X3D model already provides the tree (graph of VRML/X3D nodes), it's a little too complicated to be used at each render call. It's especially true for VRML <= 1.0 (where properties may "leak out" from one node to the next), VRML/X3D >= 2.0 cleaned a lot here but still some work must be done when traversing (like accumulating transformations).
Bounding box of this visibility sensor instance, already transformed to global VRML/X3D scene coordinates. That is, transformed by parent Transform and similar nodes.
