I've been playing around with Direct3D IM for a while now (about 2 weeks) and i've been doing fine except for a little problem I've noticed: The persective projection matrixes i'm using seem a bit off.

What I'm using is from the Direct3D IM Tutorial 1, which is this:

D3DMATRIX matProj = mat;
matProj._11 = 2.0f;
matProj._22 = 2.0f;
matProj._34 = 1.0f;
matProj._43 = -1.0f;
matProj._44 = 0.0f;

Im pretty sure this isn't the correct way to make a projection matrix, but then again, I really don't know what i'm doingn . So my question: Whats the correct way to make the perspective projection matrix? Sample code would be greatly apprectiated, although any answer is welcome!

Hi,
have a look at the "d3d_util.cpp" and the samples, try out the projection matrices used there and have a look at the sources.
