Is it posible to set up a projection matrix that gives a vanishing point centered to the 2d, x + (width/2) and y + (height/2) of a quad? This is a bit like the ortho projection, but gives some depth when doing rotations. [Edited by - darrenmarklines on May 24, 2006 5:26:42 AM]

You can probably do it using D3DXMatrixPerspectiveOffCenterLH (where the off-center is the key to moving the vanishing point). Sorry, I can't give you more detailed information -- I've never tried it.

Thanks John, I've started looking into that, but I have to say the SDK documentation on it is crap.
