<p>This is a demo of real-time <em>face deformation</em> with a parametric model using the javascript library <a href="https://github.com/auduno/clmtrackr"><em>clmtrackr</em></a>. Click start, keep your face still until the facemodel has fitted and try selecting some presets or adjusting the parameters on the right hand side.</p>
<p>Note that this demo works best with good, even lighting. The demo also needs support for WebGL, and works best in Google Chrome.</p>
