Class TPointSetNode_1

Unit

X3DNodes

Declaration

type TPointSetNode_1 = class(TAbstractGeometryNode_1)

Description

Geometry node allowed only in VRML <= 1.0.

In VRML 1.0 shape nodes are allowed pretty everywhere, while VRML 2.0 has different idea of how shapes are handled (they must be inside Shape node), so no shape node is suitable at the same time for VRML 1.0 and VRML 2.0.
