问题
I'm trying to walk through these two Project Tango Unity tutorials: https://developers.google.com/project-tango/apis/unity/unity-depth-perception https://developers.google.com/project-tango/apis/unity/unity-motion-tracking
In each of them I get stopped in my tracks by what appears to be a lack of a Unity Plugin (I assume from the Tango SDK .unitypackage). I followed the instructions to import the downloaded Tango SDK .unitypackage but for some reason don't have to option to add a PointCloud component (for the depth tutorial) or a Sample Controller (for the motion tracking tutorial).
I've tried following the tutorial with both Unity 4.6 (as it seems the tutorials were based off of) and the latest version of Unity 5 on a Mac.
Can anyone offer some guidance on what I am overlooking or doing wrong?
