(...) Jim, 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 (...) (18 years ago, 19-Mar-07, to lugnet.cad.ray, FTX)

(...) 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 (URL) LDraw unit> is equal to 0.4 mm, then the conversion probably is (...) (18 years ago, 19-Mar-07, to lugnet.cad.ray, FTX)

(...) Hmmm. It would appear that using the Potrace API and the Triangle API would do almost all the difficult work for software of this sort. I might look into restarting the project although I'm not sure how far I could get with it. Of course if (...) (18 years ago, 19-Mar-07, to lugnet.cad, FTX)

--snip-- (...) Unfortunately I got too busy with other things and kind of let is slide. With a rewrite in a compiled language and using a decent triangulation (such as the one Ross uses) and vectorisation algorithm I suspect it could be made to work (...)

(Moved to lugnet.cad.ray.) (...) 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 (...) (18 years ago, 19-Mar-07, to lugnet.cad.ray, FTX)

(...) Thanks for the tip, Tim! The point about LDraw (and POV-Ray) objectives being comprised of surfaces rather than solids is worth keeping in mind, too. After re-rendering the little test scene with maxtracelevel set to 8, I realized that the (...) (18 years ago, 19-Mar-07, to lugnet.cad, lugnet.cad.dev, lugnet.cad.dev.mac, FTX)

--snip-- (...) Hi Jim, The second error there is certainly to blame for the opacity. You need to add a line globalsettings maxtracelevel N where N is high enough (probably 8 will do). Partially this is because LDraw parts are constructed of surfaces (...) (18 years ago, 19-Mar-07, to lugnet.cad, lugnet.cad.dev, lugnet.cad.dev.mac, FTX)

(...) 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 (...) (18 years ago, 19-Mar-07, to lugnet.cad, lugnet.cad.dev, lugnet.cad.dev.mac, FTX)

(...) 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 (...)
