TangentGenerator Class Reference
#include <mesh.h>
Class Description
TangentGenerator is a class that defines the tangent space used by Mesh objects.
"Tangent space" is a coordinate system defined per vertex on a mesh, with its coordinate basis defined by the normal vector (which points away from the mesh), and the binormal and tangent vectors which are all orthagonal to each other. They can be calculated in different ways.
TangentGenerator is derived from TreeNode, so that it can be made a child of the mesh.
If your graphics pipeline demands its own particular way of defining tangent space, you can override this class and its methods. To create your own:
- Write a plug-in that defines your own class derived from TangentGenerator.
- If you need to, override the TreeNode::OnLinked() method. This will be called when your TangentGenerator node is linked to a mesh object. You can initialize any internal data.
- Delete the existing TangentGenerator plugin, and copy yours into the plug-in folder.
On OSX, this plugin (TangentGenerator.dylib) is found in the Mudbox 2010 package, under Contents>MacOS>plugins. On the PC, it is found in the work dir folder, under "plugins"
