Class TProximitySensorInstance

Unit

CastleShapes

Declaration

type TProximitySensorInstance = class(TShapeTree)

Description

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).

So we process VRML/X3D tree to this tree, which is much simpler with all the geometry nodes (TAbstractGeometryNode) along with their state (TX3DGraphTraverseState) as leafs (TShape).
