Description
Methods
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. |
class function ForVRMLVersion(const Version: TX3DVersion): boolean; override; |
|
This item has no description. Showing description inherited from TX3DNode.ForVRMLVersion. Some nodes are present only in specific VRML/X3D version. This functions decides it. For example some nodes can only work in VRML < 2.0, some others only in VRML >= 2.0. There are even some pairs of nodes: for example TConeNode_1 works with VRML < 2.0, TConeNode works with VRML >= 2.0. NodesManager will use this. Default implementation of this function returns always In practice I only use this function when various VRML/X3D versions specify the same node name but

function InternalCoord(State: TX3DGraphTraverseState; out ACoord: TMFVec3f): boolean; override; |
|
This item has no description. Showing description inherited from TAbstractGeometryNode.InternalCoord.
Return node's list of coordinates. Returns In base TAbstractGeometryNode class this always returns Override this for descendants that have some kind of "coord" field, then this should return For VRML 1.0, coord may be taken from State, that's why we have to pass current traverse state here. |
function CoordField: TSFNode; override; |
|
This item has no description. Showing description inherited from TAbstractGeometryNode.CoordField.
Node's "coord" field where you can place TCoordinateNode, or This gives you more possibilities than the InternalCoord and InternalCoordinates methods (as you can assign texCoord using this). However, it doesn't work for old VRML 1.0 (since they have coordinate information, but no "coord" field). |

procedure CreateNode; override; |
|
Create node fields and events. |
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. |
