Hi,

It's difficult to say without seeing what you're seeing, but it sounds pretty normal for when you're getting started with 3D.

I recommend getting to grips with the near and far plane distances, and the field of view. If the near plane is too close to the camera, you can get some wierd stuff. As a point gets to the plane the camera is on, the screen positions shoot up to +ve infinity.

Try out some different values. Preferably binding keys to the values so you can tweak them in real time.

Doing this, and drawing lots of diagrams on paper should help you find something which works.

Mark.
