hi! How do you switch between parallelprojection and centralprojection in DX? That seems extremely hard to do!.. But then again, I''m new at this

If it''s to hard to do, do you have a link to a demo? thanx "No lies of sugar can sweeten the sournes of reality" }+TITANIUM+{ A.K.A. DXnewbie[onMIRC]

Have a look at the D3DXMatrixPerspective* and D3DXMatrixOrtho* functions, from the SDK docs. The LH (left hand) ones are with the z-axis into the screen, and the RH ones (right hand) are with the z-axis out of the screen, like the OpenGL coord system.
