STL
Stereo Lithography file format parser
Install
npm install stl
Use
Convert binary stl to ascii stl
var stl = require('stl')
var fs = require('fs');
var facets = stl.toObject(fs.readFileSync('/path/to/binary.stl'));
fs.writeFileSync('/path/to/ascii.stl', stl.fromObject(facets));
Convert ascii stl to binary stl
var stl = require('stl')
var fs = require('fs');
var facets = stl.toObject(fs.readFileSync('/path/to/ascii.stl').toString());
fs.writeFileSync('/path/to/binary.stl', stl.fromObject(facets, true));
Object Structure
toObject
and fromObject
use the following array structure
{
description: "abc 123", // (optional)
facets: [
{
normal: [x, y, z],
verts: [
[x, y, z],
[x, y, z],
[x, y, z]
]
// attributeByteCount (optional uint16)
}
// repeats ...
]
}
Streaming
fs.createReadStream('./test/ascii/tri.stl')
.pipe(stl.createParseStream())
.on('data', function(object) {
/* first object will be:
{ description: "BOLLEN"}
*/
/*
second object is a facet which looks like:
{
normal: [ 1, 0.5, 0.25 ],
verts: [ [ 10, 10, 10 ], [ 4, 4, 4 ], [ 5, 5, 5 ] ]
}
