The aspect ratio shouldn’t make enough of a difference to put the camera
out of the ship. It should only change the cropping. If you have the same
aspect ratio, you should should get nearly pixel-perfect alignment of all
polygons that don’t involve reflection or refraction. I’m not sure if this
is a Mac-specific bug, or if you did something that I haven’t done in my
testing on Windows.

You’re right - it does work. I retried it with L3P output and the view is
positioned correctly. My previous effort used POV-Ray code from Anton’s
converter. That’s not necessarily the reason it didn’t work before, though:
it was late and I was tired. At any rate, LDView is certainly exonerated
(not that it was accused).

I think Anton’s library isn’t in LDraw units. Since the camera placement is
in LDraw units, it won’t work right. If you know the conversion factor, you
can probably multiply the camera location by that and have it work.

Ah, that’s a logical explanation. I just looked in the manual.txt that came with
Anton’s part library and it does state that it considers a POV-Ray unit 1
millimeter. If one LDraw
unit is equal to 0.4 mm, then the conversion probably is straightforward (I
haven’t tried it). I hate to provoke feature creep, but maybe LDView could
select which units to output the camera in?
