Is there a way to get the number of polygons in a scene?

Question

With three.js , is there a way to retrieve the polygon count of a scene? I did a search, but the only results that pop up at related to actual polygons and whether meshes have too many, etc.

Answer 1

I believe renderer.info.render.faces may be what you're after.

Answer 2

[ Update ] On Three.js revision r100 you would get that data through:

renderer = new THREE.WebGLRenderer();
// Code that loads your geometry here
console.log( renderer.info.render.triangles );

This same object has several a lot of data that can give you a hint over your memory leaks, so you might just want to console log the whole renderer object and browse all of its properties!
