 | ARWorldOriginHelper Class |
A helper script to set the apparent world origin of ARCore through applying an offset to the
ARCoreDevice (and therefore also it's FirstPersonCamera child); this also provides
mechanisms to handle resulting changes to ARCore plane positioning and raycasting.
This class SHOULD be used when doing any ray casting - especially if cloud anchors and world origin is being used
in your app.
