Transform3D ortho method

[endolf]

I saw the ortho method on the Transform in Agency9 and I figured I'd re-examine my Java3D HUD.

If I attach a transform group to the viewing paltform geometry node, and call orth on it, with 0,canvas width, 0, canvas height, -1, 1 I'm thinking that any geometry under it, can be specified in essentially pixel positions.

Am I right?

Does anyone have any examples?

Cause it doesn't seem to work in my tests.
