[PD] working with 3d objecs in GEM

[andreithomaz]

hello list,

I am starting to work with 3d objecs, loaded from .obj files, using Pure 
Data + GEM.

Has anybody experience with this kind of thing? I tried some mazes 
created with blender and exported to .obj with Crossroads, but they were 
not correctly exported... Do the models need to be composed only by 
triangles? To be a mesh only? I will make some tryings now but, if 
somebody has already worked with 3d objects, please, help me :-)

thanks,
andrei
