Yep, that was EXACTLY what I was thinking of. The convertor should create the needed views (all the rotations), and if it can handle the scaling too, so much the better. Just scaling bitmaps down in an image editor gives weird artifacts if you're (...) (26 years ago, 16-Feb-99, to lugnet.trains, lugnet.cad.dev)

If we just register the port information for the relevant parts (road plates, track, and monorail track), and inline all sub-files (not including parts) the inlined version of the model will contain indirect (...)

This sounds like an excellent idea, however I'm not sure how to implement it. If it were a built in feature of Track Designer it would require that the entire rendering engine of LDraw be built into TD. A bit daunting! If it were built into LDraw, (...)

(...) Track Designer can already automatically rotate [1] and scale any new bitmap that you give it. I'm not sure why you would want to do this in an image editor? What are the weird artifacts that you are referring to when using magenta as the (...) (26 years ago, 16-Feb-99, to lugnet.trains, lugnet.cad.dev)

(...) A stand-alone utility could call LDraw (or LDLite) to produce the images, but extract the (port) information directly from the .DAT file. Calling into LDraw/LDLite is pretty easy -- both programs are command-line driven. The utility would have (...) (26 years ago, 16-Feb-99, to lugnet.trains, lugnet.cad.dev)

(...) I'm not too familiar with LDraw, can I call it with a design (.DAT file) and a viewpoint and get back a bitmap somehow? Matt (26 years ago, 16-Feb-99, to lugnet.trains, lugnet.cad.dev)

(...) Yep. Pass in a .DAT filename, and include the -MS parameter (for Mode Save). A bitmap will be created in the ldraw\bitmaps directory. It will have the same filename.

(...) But rotations in 22.5 degree increments would be better, of course, and 11.25 might even be best, as we are then at the resolution of a curve segment, no? Since that requires rather complex calculations, it's more natural to have a rendering (...) (26 years ago, 17-Feb-99, to lugnet.trains, lugnet.cad.dev)

(...) No, curves are 22.5 degrees. If you give Track Designer bitmaps at 0, 22.5, 45 and 67.5 degrees it can generate all the other possible rotations. However, the existing registry only has track at all these rotations, road plates, monorail[1] (...) (26 years ago, 17-Feb-99, to lugnet.trains, lugnet.cad.dev)

(...) Duh, yes. 11.25 is just wishful thinking. Never mind. Well one teeny downside to your switch proposal is the new geometries that would result. worth it though, to be free from the tyranny the current geometry imposes. (26 years ago, 17-Feb-99, to lugnet.trains, lugnet.cad.dev)
