Direct3D transformations that works best is :
ScreenCoord = ProjectionMat * ViewMat * WorldMat * ObjectCoord
As OpenGL uses only two matrices, I combined PROJECTION and VIEW into
OpenGL's GL_PROJECTION matrix and the WORLD into GL_MODELVIEW.
If anyone has a good explanation of the three different matrices in
the SDK online documentation, feel free to point it to me. For example,
which matrices transform lights ? In OpenGL only the PROJECTION matrix
transform the lights, not the MODELVIEW. Using the matrix names, I
supposed that PROJECTION and VIEW (all 'camera' related names) do
transform lights, but WORLD do not. It may be wrong though... */
/* After reading through both OpenGL and Direct3D documentations, I
thought that D3D matrices were written in 'line major mode' transposed
from OpenGL's 'column major mode'. But I found out that a simple memcpy
works fine to transfer one matrix format to the other (it did not work
when transposing)....
So :
1) are the documentations wrong
2) does the matrix work even if they are not read correctly
3) is Mesa's implementation of OpenGL not compliant regarding Matrix
loading using glLoadMatrix ?
Anyway, I always use 'conv_mat' to transfer the matrices from one format
to the other so that if I ever find out that I need to transpose them, I
will able to do it quickly, only by changing the macro conv_mat. */
