If the wires of thru hole components are supposed to look vaguely realistic on zoom, at least 20 triangles per cylinder are needed. The 90° bend needs another 40 triangles. Every triangle requires 3 nodes and every node includes three coordinates plus orientation. That way, the stl size of a simple resistor may easily xceed the memory footprint of its footprint by two orders of magnitude.

VRML is very similar to STL in that both are formats to export from 3D CAD applications to rendering software like blender. They both communicate just meshes, no objects. Beause of this, they are they are less useful as imports for 3D editing. From mechanical point of view these mesh formats are one-way roads. ---<)kaimartin(>--- -- Kai-Martin Knaak Öffentlicher PGP-Schlüssel: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x6C0B9F53 _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
