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.

Create node fields and events.

	class function ForVRMLVersion(const Version: TX3DVersion): Boolean; override;

Properties

	property FdStartIndex: TSFLong read FFdStartIndex;
Internal wrapper for property StartIndex. This wrapper API may change, we advise to access simpler StartIndex instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

	property FdNumPoints: TSFLong read FFdNumPoints;
Internal wrapper for property NumPoints. This wrapper API may change, we advise to access simpler NumPoints instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).
