Hello! How do I realize a quite efficient matrix multiplication in a vertex program?

Matrix multiplication is O(n^3) operation. For 3x3 matrix that is 9 DP3 instructions and for 4x4 its 16 DP4. There are a few "hacks" if your matrices are in some special form but you''ll have to profile it if ti''s worth the trouble

You should never let your fears become the boundaries of your dreams.

Thanks a lot.
I''ve just tried it with cg and noticed that their compiler is very cool! :-) I''ve expected a lot more instruction at my first VP!
