  Re: Patterns suck!
 
(...) That's true. Bmp2dat needs some real edge tracking algorithms instead of just runlength encoding. Something like this. (URL) also needs an autorotate function. Just look for the longest straight line near 90 or 0 degrees and rotate it to (...) (21 years ago, 5-May-04, to lugnet.cad.dat.parts)

(...) Or you could search the net for vectorizer programs like this one. (URL) a free vectorizer with source code. (URL) wonder how hard it would be to modify it to handle color and output ldraw format. Enjoy, Don (21 years ago, 5-May-04, to lugnet.cad.dat.parts, lugnet.cad.dev)
 
  Re: Patterns suck!
 
(...) I'm gonna have to look into this again. Vectorizers are cool. Here's some more opensource code (3 URLs) a really nifty description of how to use the potrace vectorizer to generate edges, and the netlib triangulator to create the triangles. (...)

  Patterns, simplified
 
(...) I'm inferring that you are talking about converting a scanned image into a pattered subfile for a part? Then, optimally, the process requires the following discrete phases: 1) Someone[1] scans a patterned part at high resolution into an agreed (...)

  Re: Patterns suck!
 
(...) IMHO a mosaic can't replace true vectors or poligons. regardless of the resolution you will still need an obcene amount of quads to define the shapes. it won't be the giant leap but it would be the small step if the LSC could with a new (...) (21 years ago, 6-May-04, to lugnet.cad.dat.parts)
