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?

In the Converter I divide every coordinate the LDraw model has by 2.5 and
then I end up with the millimeter system I digitized everything with. I have
(since I started to build my Library starting in 1992) always used
millimeters when measuring every single brick.

Hi, Anton! Thanks for the explanation. That is a straightforward conversion. I
divided LDView’s reported camera location and look_at coordinates by 2.5,
reversed the sign of the y coordinates, used the default right vector
(positive x), and it came out right:
Relatively speaking, of course. The scene itself needs work.
I am pleased to discover your library and how to use it, thanks in large part to
James Reynolds’ recent video.
Thanks,
Jim

| (...) Jim, You're welcome! What you could do with the scene is put a hundreds of thousands unit tall white box (not an infinitive plane, they'll add up to your rendering times!) behind the camera, it'll give you some indirectional lighting like I (...)
