Hi,

why do you want that matrix?

just in case any of these do:

- You can get the current active modelview matrix by calling glGetFloatv(GL_MODELVIEW_MATRIX, mat);
(for more information, http://linux.die.net/man/3/glgetfloatv)

- For how to generate those matrixes and others you can just google around and get something like this: http://gpwiki.org/index.php/3D:Matrix_Math
