I have a function:

```auto
 function removeBySid(sid) {
            scene.traverse(function(node) {
                         if (node instanceof THREE.Mesh) {
                            if (node.geometry) {
                                node.geometry.dispose();
                            }
                            if (node.material) {
                                node.material.dispose(); 
                            }
                         }

                        scene.remove(node);
            });
        };

```

how will i be able to tell if geometries and materials have been disposed? is there a way to check?

Hello s333,

If you are using three.js [webGLRenderer](https://threejs.org/docs/index.html#api/renderers/WebGLRenderer), there is a `.info` property that should give the info you are looking for:

**memory** :

- geometries
- textures

**render** :

- calls
- vertices
- faces
- points

**programs**

I use to integrate `threex.rendererstats` from [learningthreejs.com](http://learningthreejs.com/blog/2013/06/25/monitor-rendering-performance-within-threejs/), which encapsulate the .info details into a little app. Unfortunatly, the app stopped working a few version back. Maybe someone could refresh the code as it gives very usefull details, specially when one starts looking a memory/perf management…

Another option would be to use the shader editor from [firefox dev edition](https://www.mozilla.org/en-US/firefox/developer/) that gives the loaded/unloaded programs.
