3D data set to stereo lithography input
Mon, 07/16/2012 - 06:24 am
I need to get data describing a 3D surface (from AFM data... it's just z values sampled over a uniform xy grid) to a stereo lithography machine. Has anyone tackled this before?
Apparently, an stl file is a standard input file for these devices. This file describes the surface via a mesh of triangles along with the normal to each triangle. The file then consists of an xyz triplet for each vertex of each triangle along with the normal. I haven't found anything (yet) in Igor to create the mesh. Image transform seems to be the likely suspect, but this hasn't panned out, unless I'm missing something.
I'm hopeful this post will generate some ideas.
