Yair,
Doesn't the dBase process communicate "upstream"? Exactly what does that
mean? What is upstream of dBase?????
Matrices:
I feel for you, I really do. <g>
Remember that performer and OpenGL write their matrices transposed from
each other....
[XYZW]' = [XYZW]*[A]*[B]
where
(A) (DCS or whatnot)
\
\
(B) (next DCS)
note that [XYZW] is a row vector not a column vector....
If you search the archives for last month or the one before it, you will
find a rant by me (I am feeling much better now) and a few helpful
suggestions. If you write down the formula and it is correct then I
suspect that your matrices aren't quite what you think they are.
(perhaps they are being corrupted or something?)
