Its not 3D really, its a plane with a painted texture on it. If you wanted tracks with height, extruded from copper, THAT would take serious work ;) Its also rough around the edges.. I need to fix the code which allocates enough memory to render a given size of board. (For playing so far, I just allocated enough memory for the board I was testing with) > The 3d of several planes at heights would be a good 3D model of a > stuffed board...for box planning purposes... I was thinking it would be easy enough to do the layer stackup in GL, assuming we depth-sort them. That is inexpensive for our application... expensive for 3D geometry in a big un-ordered data-set. I do have the urge (but not time) to find some 3D models for components. > So, how fast could you hook pcb to blender? (Just kidding, sort of...) I've not used blender.. doing this properly as a 3D model is going to be a lot more work than a quick trick to use OpenGL for rendering the image of the board. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
