    Re: Fun with LDView Fly Through (A Minifig's Eye View) —Travis Cobbs
   (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)
   
        Re: Fun with LDView Fly Through (A Minifig's Eye View) —Jim DeVona
   (...) 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)

   (...) Hi, Anton! Thanks for the explanation. That is a straightforward conversion. I divided LDView's reported camera location and lookat coordinates by 2.5, reversed the sign of the y coordinates, used the default right vector (positive x), and it (...)

   (...) 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 (...)
