Class TLocalFogNode
Unit
X3DNodes
Declaration
type TLocalFogNode = class(TAbstractChildNode)
Description
Simulate atmospheric fog effects (for a part of the scene) by blending with the fog colour, based on the distance from the viewer. This is the "local" version of the TFogNode, this affects only the sibling nodes of the LocalFog node, not the whole scene.

procedure BeforeTraverse(StateStack: TX3DGraphTraverseStateStack); override; |
|
This item has no description. Showing description inherited from TX3DNode.BeforeTraverse.
Override these methods to determine what happens when given node is traversed during Traverse call. The main use of this is to operate on TX3DGraphTraverseStateStack.
Remember to always call inherited when overriding. In BeforeTraverse and MiddleTraverse you should call inherited at the beginning, in AfterTraverse inherited should be called at the end.
Besides changing StateStack.Top fields, you can do push/pop on the stack. Remember that if you do StateStack.Push in BeforeTraverse, and then you must call StateStack.Pop in AfterTraverse.

procedure GroupBeforeTraverse(const State: TX3DGraphTraverseState; var WasPointingDeviceSensor: Boolean); override; |
|
This item has no description. Showing description inherited from TX3DNode.GroupBeforeTraverse.
React when this node is processed as an immediate child of a grouping node, within grouping node's BeforeTraverse.

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.
|
|
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.
