See the demo swf at bottom of the post.
V, F and N to control camera internals (+shift/+control to decrease values). Hit any key to ‘fire’ your ray

thanks for the discussion on twitter, I figured we could follow here to have more space.
I see what you mean about having to unproject twice to get the ray because of the way the rays are based on camera position.
It seems just a little bit more abstract than I can wrap my mind around.
Im curious as to what advantages ortho mode has for the camera or view cone.
I think the “or…” sparked some curiosity as to what uses this might have. Thanks again for the discussion and for your work for the engine.
