Class TShapeTreeTransform

Unit

Declaration

type TShapeTreeTransform = class(TShapeTreeGroup)

Description

Node of the TShapeTree transforming it's children.

It's ideal for handling VRML 2.0 / X3D Transform node, and similar nodes (MatrixTransform and some H-Anim nodes also act as a transformation node and also may be handled by this).

Properties

Public property TransformNode: TX3DNode read FTransformNode write SetTransformNode;

Transforming VRML/X3D node. Always assigned, always may be casted to ITransformNode interface. Note that it doesn't have to be TTransformNode, e.g. TBillboardNode also supports ITransformNode.

Public property TransformState: TX3DGraphTraverseState read FTransformState;

State right before traversing the TransformNode. Owned by this TShapeTreeTransform instance. You should assign to it when you set TransformNode.
