I just tried to look into an AOI portable.obj model of a laptop --> 580 kB zipped and 2.8 MB expanded. Nice ubunto logo though ;-) Nah, thanks, I think it's a bit too expensive on memory and IMHO vertexes resemble "minced meat" --> try putting it together to get the original cow ;-) I'd rather have 3D primitives like cubes, cylinders, spheres, toroids etc. Kind regards, Bert Timmerman. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
