 | | Help Needed: Boundary Box Utility [DAT]
|
|
Could somebody please make a utility that calculates and creates a boundary box for a .dat file? I want it to be able to take a DOS command line like "bbox.exe C:\Ldraw\Models.Mymodel.dat" and it should create 'MyModel.box' in the same directory. An (...)

(...) I don't think I can do this right away since I already have 2 actual bug reports and an enhancement request in for ldglite. (I don't get many of these so I like to give them priority). It shouldn't be too hard to do though. Everything you need (...) (23 years ago, 14-Aug-01, to lugnet.cad, lugnet.cad.dev)

Thank you Don. I will give it a try tonight, but I'll probably fail. I'll let you know. I need it for two purposes: 1. Making an overview map of Datsville from the subdivision in town.dat. (Maybe post-editing of the Y and E values by hand). 2. (...) (23 years ago, 14-Aug-01, to lugnet.cad, lugnet.cad.dev)

Thank you very much! I tested it on "my home" in Datsville, and it worked perfectly well, exactly as I want it to. With these two lines and viewed in L3Lab, any flaws would have been discoved: 1 16 0 0 0 1 0 0 0 1 0 0 0 1 ttore.dat 1 47 0 0 0 1 0 0 (...) (23 years ago, 15-Aug-01, to lugnet.cad, lugnet.cad.dev)

That's it for tonight. I bboxed the parts of Datsville and labelled them after their names in town.dat (URL) (19 Kb) Next step: adding *a few* key buildings to help orientation. Tomorrow... /Tore (23 years ago, 15-Aug-01, to lugnet.cad, lugnet.cad.dev)

This is great! An idea: if bitmaps were created of the model from 6 directions (left, right, bottom, top, front, back), you could texture map those to the boundary box (inside, to make sort of a 6 point, 3 plane cross intersecting in the center) and (...)

You could specify (or firmly recommend) in the future that models must posses boundary boxes measured in degrees of tilewidths (or half-tilewidth's). Anything less than that would be considered a prop. Props would then be dealt with seperately, just (...) (23 years ago, 16-Aug-01, to lugnet.cad, lugnet.cad.dev)

Here is another idea for optimizing dat models. It isn't a very good one, but, it just seems more realistic than what I said earlier (writing a utility smart enough to optimize an entire model). One could write a utility that presents each polygon (...) (23 years ago, 16-Aug-01, to lugnet.cad, lugnet.cad.dev)
