Class TTangentNode
Unit
Declaration
type TTangentNode = class(TAbstractGeometricPropertyNode)
Description
Tangent vectors information, for bump mapping.
If your materials use TAbstractOneSidedMaterialNode.NormalTexture then tangent vectors are used to determine the tangent space in which the normal map is applied. While the engine can automatically generate tangent vectors, it is recommended to provide tangent vectors explicitly to achieve the perfect look of the lighting, matching the software used to create normalmaps.
See Tangent node in X3D for more details what this node specifies and why is it useful.

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. | |
