I have read just about everything there is to read about TnL, but I still do not understand what the Transform-part do. Even the white-papers from Nvidia are unclear. They say two totally dofferent things.

The first explanation is that the Transform-engine converts the 3D-data from one frame of reference to another ( for example Worldspace to Screenspace )

The second explanation is that it Transforms the vertexes ( ie. rotates, scales and move them )

Do anyone here know ? Then please help me
