Class TAbstractGroupingNode

Unit

Declaration

type TAbstractGroupingNode = class(TAbstractChildNode)

Description

Base node that may contain children nodes. Note that this descends from TAbstractChildNode, so it can be inserted as child of another grouping node. So, you can create a hierarchy of nodes with any depth.

Handles TTransformFunctionality for any descendant that defines an instance of it.

Description

Methods

Protected function SeparateGroup: boolean; virtual;

If True (default implementation in this class), then this really behaves like a grouping node. If False, this allows everything to "leak out" (transform changes, VRML 1.0 state changes etc.). Possibility useful for VRML 1.0 extension https://castle-engine.io/x3d_extensions.php#section_ext_wwwinline_separate
