OK, This SOUNDS nice, but anyone who knows matrix math KNOWS you can't
multiply
0
1 * 4x4 Matrix
0
1
Now you CAN do
0
1
4x4 Matrix * 0
1
I am assumeing that this wierdness might have something to do with the
fact that performer matrices print out their translation elemnets in the
4th row instead of the 4th column like a NORMAL GL matrix.
Can someone PLEASE explain in what freaking order the DCS(SCS,FCS) in a
scene graph are multiplied in!!!! I would greatly appreceate it if the
word Postmuliply wasn't used at all. Please, Please, Please use normal
MATH notation. (4x4)*(column vector) = (transformed vector)
If am not an idiot, but something about performer math is really
odd........
Please if you can CC a copy to my address as I only get info performer
in digest mode.
Thank you in advance.
