Occlusion in Tango AR Camera
<p>I have a simple Tango Unity app which uses the <code>Tango AR Camera</code> prefab to display a 3D object in augmented reality.</p>

<p>Following <a href="https://stackoverflow.com/questions/34957433/occlusion-in-ar/35000356">this question</a>, I wanted to try out the <a href="https://developers.google.com/tango/apis/unity/reference/class/tango-a-r-screen#m_enableocclusion">occlusion feature</a> provided by <code>TangoARScreen</code>. </p>

<p>Therefore I have:</p>

<ul>
<li>checked the "Enable Occlusion" checkbox</li>
<li>enabled depth detection in <code>Tango Manager</code></li>
<li>added a <code>Tango Point Cloud</code> with <a href="https://developers.google.com/tango/apis/unity/reference/class/tango-point-cloud#m_updatepointsmesh">Update points mesh</a> enabled.</li>
</ul>

<p>However the 3D object never gets hidden by foreground real-world objects. What am I missing?</p>

<p>Is there any sample project that demonstrates this "Enable Occlusion" feature?</p>
