Three.js: Accessing Geometry Data from OBJLoader

Created on 17 Dec 2014 · 5Comments · Source: mrdoob/three.js

For some reason, I'm unable to access geometry data (geometry.face, geometry.vertices, etc) using OBJLoader. This data is available using OBJMTLLoader, but when I log the object to the console with OBJLoader, the properties aren't there are on the javascript object.

Alright, I simply had to put "new" in front of "THREE.Geometry()":

var geometry = new THREE.Geometry().fromBufferGeometry( bufferGeometry );

I assume I need to take this to stack overflow, just a heads up

three.js is slowly transitioning from Geometry to BufferGeometry, which is more memory efficient and results in faster load times. Geometries returned by OBJLoader are now of type BufferGeometry.

If you really need Geometry you can do this:

var geometry = new THREE.Geometry().fromBufferGeometry( bufferGeometry );

Thanks gents. Sorry for the false alarm.
