I was envisioning how an LDraw renderer would be implemented if it were done with OpenGL, and I've arrived at some questions that I can't answer for myself. I'm particularly wondering about line type #5, the optional line. According to the LDraw (...) (20 years ago, 24-Jan-05, to lugnet.cad.dev)

(...) Yes,I am very well aware of the multitude of camera settings POV offers, and I haven't yet decided which way to go. The fastest way may be to run my own race using my own META statements: 0 LDA CAMERA.POSITION x y z 0 LDA CAMERA.LOOKAT x y z 0 (...) (20 years ago, 24-Jan-05, to lugnet.cad.dev, lugnet.cad.ray)

Personally I don't think using GTK under Windows is a good idea. I've worked with it before and even released an application that used it and you won't believe the amount of people that have trouble using a Windows application with controls that (...)

(...) POV-Ray cameras can do alot. Besides just having a location and direction, you can have a zoom, focus, you can specify the direction in the form of "look at", and more. If you are going to have a camera.dat, you might consider having it be (...) (20 years ago, 24-Jan-05, to lugnet.cad.dev)

(...) I'm sorry if I was unclear. Earlier in the thread I put forward Bens wheels as an example and continued that example here. I realise they would not be eligible for inclusion in the official Ldraw library, and would not submit them. This thread (...) (20 years ago, 23-Jan-05, to lugnet.cad.dev)

(...) Maybe I'm missing the point here, but if this whole discussion is about Ben's excellent independently produced wheels, then whether or not they are modelled appropriately for inclusion in the official LDraw library is academic. The official (...) (20 years ago, 23-Jan-05, to lugnet.cad.dev)

(...) No DAT part can provide a perfect render without using some substitutions - flat polygons just can't do perfect curved surfaces. But that's another issue. I have recently finished re-authoring Ben's wheels (URL) (waiting for his OK before I (...) (20 years ago, 22-Jan-05, to lugnet.cad.dev)
