P(x1,y1,z1,w1)=P(x0,y0,z0,w0)*M ??

x1= _11*x0 + _21*y0+_31*z0+_41*w0
y1= _12*x0 + _22*y0+_32*z0+_42*w0

whether you or me say wrong?
M11,M12,M13 is translation.
M14,you say right,is used for perspective projection.

harrrmm  ...........I think that in Grap API the matrix is hard to understand
But easy to use. Just like <<Hack empire>>...
you say m11 m12 m13 is translation  is very right !!! so am i
(A*B)t  =Bt *At      ( At is invers Matrix of A,etc)
So how you define your matrix,how to understand them how to Apply them in yourself order ,at last you send them to API....
Remember,,there is nothing absolute in matrix algorithm....
