I''m a newbie at 3D graphics, But have been programming for years. I''m learning DirectX 8 and have a question on the 3D coordinate system it uses.
I know the center of the world is coordinate 0,0,0. Which is fine, But I''m used to 2D coordinate in the Windows GDI system, And having a negitive coordinate is confusing to me. Can I just offset the camera and use postive coordinates only? In other words, 0 X, 0 Y would be the upper left hand corner of my game world. 0 Z would be the closest point to the camera.
Would this work? Or should I just give up and let the 3D system with negitive coordinate ware onto me until I get it?
