Line 1:		Line 1:
			STL (Stereo Litography) files are intended to represent three-dimensional shapes using information about the surface of a shape. STL files do not store any volumetric information. Surfaces are triangulated, and the triangles that compose a shape are described using Cartesian points.

			Note that STL files do not know anything about scale - all measurements and distances are relative and may be scaled.

	</pre>		</pre>

	~~Quick example of how~~ to ~~use~~ this ~~utility~~:		Here is the javascript file that I used to convert this shapefile to a stl file:

	<pre>		<pre>
			$ cat stlify.js
	var fs = require('fs');		var fs = require('fs');
	var shp2stl = require('shp2stl');		var shp2stl = require('shp2stl');
	var file = '~~SanFranciscoPopulation~~.shp';		var file = 'Elev_Contour.shp';
	shp2stl.shp2stl(file,		shp2stl.shp2stl(file,
	{		{
	width: 100, //in STL arbitrary units, but typically 3D printers use mm		width: 100, //in STL arbitrary units, but typically 3D printers use mm
Line 61:		Line 62:
	},		},
	function(err, stl) {		function(err, stl) {
	fs.writeFileSync('~~SanFranciscoPopulation~~.stl', stl);		fs.writeFileSync('SeattleContours.stl', stl);
	}		}
	);		);
			</pre>

			To run this, just pass it to node:

			<pre>
			$ node stlify.js
			bounds: Infinity Infinity -Infinity -Infinity (spherical)
			pre-quantization: 111.195km (1.00°) 111.195km (1.00°)
			topology: 0 arcs, 0 points
			topojson done
			simplification: effective minimum area 0.00
			simplification: retained 0 / 0 points (NaN%)
			making top planes
			making side planes
			making bottom planes
			done making 3D planes
	</pre>		</pre>
