Environment Setup
=================
[ArEnvironment](/argaze/#argaze.ArFeatures.ArEnvironment) setup is loaded from JSON file format.
Each [ArEnvironment](/argaze/#argaze.ArFeatures.ArEnvironment) defines a unique [ArUcoDetector](/argaze/#argaze.ArUcoMarkers.ArUcoDetector.ArUcoDetector) dedicated to detection of markers from a specific [ArUcoMarkersDictionary](/argaze/#argaze.ArUcoMarkers.ArUcoMarkersDictionary) and with a given size. However, it is possible to load multiple [ArScene](/argaze/#argaze.ArFeatures.ArScene) into a same [ArEnvironment](/argaze/#argaze.ArFeatures.ArEnvironment).
Here is JSON environment file example where it is assumed that mentioned .obj files are located relatively to the environment file on disk.
