1) Yes.

You can directly use the light-normal-index for the predefined array and transform the vertices using the given scaling and translation values.

2) Sorry, don''t reminder that, but you should be able to find out by testing.

3) Because one has to convert the values to the coordinate-system used in your application. I have seen this way of conversion in GL apps before, for a D3D8 reference have a look at the samples provided by NVidia ( http://developer.nvidia.com ).

Bye
