obj-mesh

parse an obj file into the object format that mesh-viewer understands

The format that mesh-viewer understands is the same object format that the bunny and stanford-dragon packages use.

example

var xhr = require('xhr');
var objmesh = require('obj-mesh');
var through = require('through2');
var viewer = require('mesh-viewer');
 
var shell = viewer();
var meshes = [];
 
shell.on('gl-init', function () {
    xhr('/teapot.obj', function (err, res, body) {
        var obj = objmesh();
        obj.pipe(through.obj(function (mesh, enc, next) {
            meshes.push(shell.createMesh(mesh));
            next();
        }));
        obj.end(body);
    });
});
 
shell.on('gl-render', function () {
    for (var i = 0; i < meshes.length; i++) {
        meshes[i].draw();
    }
});

methods

var objmesh = require('obj-mesh')

var stream = objmesh()

Return a transform stream that expects to be written obj file contents and outputs an object of the form that mesh-viewer for each object group in the input source file.

Each object has:

• row.positions - an array of [x,y,z] arrays for each point in the mesh
• row.cells - an array of [i,j,k,...] point indexes for each point in row.positions

install

With npm do:

npm install obj-mesh
