Class TStaticGroupNode

Unit

Declaration

type TStaticGroupNode = class(TAbstractInternalGroupingNode)

Description

Children nodes which cannot be modified. StaticGroup children are guaranteed to not change, send events, receive events or contain any USE references outside the StaticGroup. This allows to optimize this content for faster rendering and less memory usage.

Description

Methods

Protected function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override;

This item has no description. Showing description inherited from TX3DNode.DirectEnumerateActive.

Enumerate all active child nodes of given node.

"Active nodes" are the ones affecting current look or collisions, e.g. from Switch node only one child will be enumerated. See Traverse for more precise definition.

"Direct" means that this enumerates only direct descendants, i.e. this is not recursive. See methods like Traverse or EnumerateNodes if you want recursive behavior.

This can enumerate both VRML1Children nodes and nodes within TSFNode and TMFNode fields.

Default implementation in this class enumerates all Children nodes of VRML 1.0. If you need to remove some children for VRML 1.0 (e.g. for Switch or LOD nodes) or add some children for VRML 2.0 you have to override this. You do not need to call inherited when overriding this — in fact, you should not, if you want to omit some nodes.

Stops and returns immediately if Func returns non-nil for some child.

Public class function ClassX3DType: string; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

Public procedure SetChildren(const Value: array of TAbstractChildNode);

This item has no description.

Properties

Public property FdChildren: TMFNode read FFdChildren;

Internal wrapper for property Children. This wrapper API may change, we advise to access simpler Children instead.

Public property FdBboxCenter: TSFVec3f read FFdBboxCenter;

Internal wrapper for property BboxCenter. This wrapper API may change, we advise to access simpler BboxCenter instead.

Public property BBox: TBox3D read GetBBox write SetBBox;

This item has no description.

Public property FdBboxSize: TSFVec3f read FFdBboxSize;

Internal wrapper for property BboxSize. This wrapper API may change, we advise to access simpler BboxSize instead.
