Base X3D node.
Almost all X3D nodes inherit from this. (Exception: X3DMetadataObject. So you cannot have metadata of metadata of...)

class function ClassNodeTypeName: string; override; |

class function URNMatching(const URN: string): boolean; override; |
|
 |
function FogTypeOrNone: TFogTypeOrNone; |
Fog type, but may also return ftNone if we are Nil (checks Self <> nil) or visibilityRange = 0.
|
 |
procedure ApplyFog(var Color: TVector3Single; const Position, VertexPos: TVector3Single; 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 Nil instance.
