Methods

Public function TransformationChange: TNodeTransformationChange; override;

This item has no description.

Public function Box: TBox3D;

This item has no description.

Public procedure SetIsActive(const Value: boolean; const Time: TX3DTime);

This item has no description.

Public procedure CreateNode; override;

Create node fields and events.

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.

Properties

Public property IsActive: boolean read FIsActive;

This item has no description.
