RHW... Can anyone tell me what RHW is? In "Programming Role-Playing Games with DirectX" by Jim Adams it says on page 185: "...this typically represents the distance from the viewpoint to the vertex along the Z-axis". But I thought the z variable is that?

RHW = Reciprocal Homogeneous W coordinate. X, Y, and Z are divided by W to determine depth.
