any suggestions???

is there somebody knows about the CEGUI,i tracked the source code,and found this framework use the below model-view matrix through glMatrixMode(GL_MODELVIEW);glLoadMatrixf(mat);and the mat is fixed as below:

2.5147607 0 0 -1287.5575
0 -3.7320509 0 1287.5575
0 0 1.6666667 0
0 0 1 1287.5575

Actually,i want use 3d tools such as 3ds-max to design my-style GUI widgets,but i cant get the camera info through this matrix,so please give me some hints!
It will be thanked!!!

I’m not familiar with CEGUI, but it has its own forums, have you tried asking there?
