procedure ApplyFog(var Color: TVector3; const Position, VertexPos: TVector3; const AFogType: TFogTypeOrNone); |
Apply fog to the color of the vertex. This can be used by software renderers (ray-tracers etc.) to calculate pixel color following VRML/X3D specifications. After all the lighting is summed up (see TX3DGraphTraverseState.Emission and TLightInstance.Contribution), process color by this method to apply fog. Does nothing if AFogType = ftNone. In this special case, it's also allowed to call this on |

procedure CreateNode; override; |
This item has no description. Showing description inherited from TAbstractBindableNode.CreateNode. Automatically generated node properties. Do not edit this file manually! To add new properties: - add them to the text files in tools/internal/x3d-nodes-to-pascal/nodes-specification/ , - and regenerate include files by running x3d-nodes-to-pascal |
![]() |
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. |
