JPCT - 3D to 2D (flat perspective)

Question

I'm using JPCT to create 3D modelling software. The center of the program has a big view of the model. There are xy, xz and yz views at the side to see each side of the model in detail.

The Problem I have is that I can not remove the "perspective" on the side views. I want a "flat top down" view. A point far in the distance should not be any closer to the center than a close point if they have the same xy position (in the xy view). In other words: "Placing the camera in infinity and then zooming in" is what I want.

I tried fiddling around with the BillBoard Matrix, but no success (I don't even know if this is the right thing to look at). Unfortunately the documentation/examples for JPCT are sparse.

Answer 1

It would appear as of late 2010 ortho is unsupported:

1. Is there a way to set an orthographic camera projection? There doesn't seem to be a way to specify the projection that the camera uses, other than setting the FOV. Perspective seems to be implied. How do I set it to ortho?

Nope, orthographic mode isn't supported, i'm sorry.
