Help about TGEA projectmatrix

Hi all:
I have a opengl-style projectmatrix that get from other program, I want to convert it TGEA-style projectmatrix, I have some confuse about TGEA render system, TGEA render via DirectX but using TGE-style matrix. I have read the GFXDevice::setFrustum function, but still can't get the correct project matrix. so my question is how to convert a exsit opengl-style projectmatrix to TGEA-style?


thanks a lot.
