JavaScript stl createParseStream Examples

Example #1

File: test.js Project: Hello1024/mesh-slice-polygon

var testStl = function(file, compare, t) {
  file = path.join(stldir, file);

  var slicer = new MeshSlicePolygon();

  fs.createReadStream(file)
    .pipe(stl.createParseStream())
    .on('data', function(obj) {
      obj && obj.verts && slicer.addTriangle(obj.verts)
    })
    .on('end', function() {
      var bounds = slicer.bounds

      t.equal(slicer.slice(bounds.max[2] + 0.1).length, 0)
      t.equal(slicer.slice(bounds.min[2] - 0.1).length, 0)

      for (var z = bounds.max[2]; z>bounds.min[2]+.1; z-=.1) {
        var res = slicer.slice(z);
        compare(res, z);
      }

      compare(slicer.slice(bounds.min[2]), bounds.min[2]);
      compare(slicer.slice(bounds.max[2]), bounds.max[2]);

      t.end();
    });
};
