I did something similar once, but for a special case of 2D with only a small number of [square]s (up to 8 or so). But the principle I used (or that I would use now, if I were doing it again) is basically: wrap each kind of geo in an abstraction, like [cad_square] instead of using [square], that uses the Gemlist info to work out where it is in space, then send a message with that info (plus what kind of geo it is) to a receiver (which might write it to a textfile or do something else with it). Optionally have a pre-render bang and a post-render bang for any headers/footers that the file format needs, and remember that you might need to get colours / materials too (I guess the GEMglVoodoo will do the trick there). In my case I used pdlua to directly write a graphgrow-engine input file, while using Pd+Gem to generate realtime previews using texture feedback. A blog post about that: http://claudiusmaximus.goto10.org/cm/2008-03-23_graphgrow_realtime_preview.html Some possibly-no-longer-working code: svn export https://code.goto10.org/svn/maximus/2008/gg/ gg > any idea would be aprreciated I think you're on the right track, but I don't know if there's an existing exporter.
