Description

Methods

Public constructor Create(const AX3DName: String = ''; const ABaseUrl: String = ''); override;

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

Constructor. Initializes various properties:

  • Name, BaseUrl are initialized from given parameters.

  • The Fields, Events lists are filled in every descendant, to have all the fields/events defined by the specification.

  • DefaultContainerField, and other node-specific stuff, is filled in descendants. This is actually implemented in CreateNode, that is called at the end of this constructor.

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.

Public procedure SetKeyValue(const Value: array of TVector3); overload;

This item has no description.

Public procedure SetKeyValue(const Value: TVector3List); overload;

This item has no description.

Properties

Public property FdKeyValue: TMFVec3f read FFdKeyValue;

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

Public property EventValue_changed: TMFVec3fEvent read FEventValue_changed;

This item has no description.
