Hello, i was experimenting with gem combining diferent generatives techniques to create 3d iterative complex shapes. I would like to use these structures for architecture and I was wondering if its possible to export the generated structures to other 3d modelling software or maybe to autocad, so the structures generated can be built in the real world. Do anybody have tried something like this?
In processing theres a library that allows to export 3d opengl shapes into dxf format that can be loaded in autocad, how difficult can it making something like this in pd? "http://www.processing.org/reference/libraries/dxf/index.html"
I was thinking that it would be possible to iterate over all the repeated geos in each shape and with gem_listinfo extract the information matrix corresponding to each geo, and then store into a text file , then use that info to rebuild the shapes in other program like autocad.
Do anybody have tried something like this?
any idea would be aprreciated
thanks
pun.

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.h...
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.

hello, i did use the same kind of technic to create .obj file, that i open and convert in blender.
here is an extern i make to speed things up and exemple how to export to a obj file... (works only with cubes)

hi, there was some talk about exporting gem to obj files on the gem-dev list. but afaik nobody got it working. I think the closest was an object by cyrille, which probably never made it into the svn... http://lists.puredata.info/pipermail/gem-dev/2008-02/003303.html there are also some experimental vertex_array objects, that might support this?? marius.
