It can be little tricky to built DirectPython if you are not familiar with
DirectX SDK. You need a relatively new platform SDK, the DirectX SDK and of
course Python libraries. Put everything together as a new project and built
it with Visual Studio 7.1 (you can use some other compilers too, but it
requires some tweaking). I might add some more help files to explain things,
but I think that very many people can or are interested in making their own
builts. But then again, I might be wrong.

Vertices that are pretransformed (FVF.XYZRHW) are not affected by
transformations. You need to apply your own calculations to them before you
render them. Use FVF.XYZ-vertices if you want to use transformation
matrices. 

However, it is possible to squeese them (XYZ) through shaders to arhieve the
same results as with XYZRHW-vertices.
