ThreeJS: loading OBJ files keeping quadrilateral faces

Question

Is it possible to load an OBJ file under ThreeJS keeping the quadrilateral faces? Here is an example:

http://www.professores.im-uff.mat.br/hjbortol/disciplinas/2014.2/hwc00001/test/threejs/viewer-04/viewer-04-b.html

Note that each quadrilateral face is rendered as two triangles in wireframe. I would like to keep the original quadrilateral faces, as shown here (in Java):

And what about a general n-polygon face in OBJ files? Is it possible to keep it?

Thanks, Humberto.

Answer 1

Unfortunately everything gets translated to triangles. However, you may be able to achieve the results you are after with this code:

var edges = new THREE.EdgesHelper( mesh );
scene.add( edges );
