Anyone who has a decent handle on directx and direct3d programming, I have been programming in directx for maybe three weeks now, and I have come up with a couple of questions that no body seems to be able to answer. I was thinking maybe someone could help me out: 1) I want to set an orthographic projection matrix in my viewport. How do I do this? 2) I know hot to turn line patterns on, but there isn''t a very extensive explanation as to how to use the D3DLINEPATTERN type in the documentation. Anyone know how to set the data into that type? 3) Along the same lines of the question above, does anyone know how I am actually supposed to set the line pattern? I know these questions could easily sound stupid or odd, but I''m new to this and any help I can get would be appreciated. ozone_blue
