Events are currently implemented in the display_JSON scene using the DrawParticleSpacePoints.js script. It relies upon a C# script called SimpleJSON which can be found here. The DrawParticleSpacePoints.js script reads in data in the Argo event display format (JSON). The datafile is currently hard coded in.
As a reminder, the MicroBooNE coordinate system is defined as:
The coordinate system that Unity implements is unfortunately left-handed, naturally conflicting with the right-handed system that MicroBooNE uses. To correct this, the x-coordinate values for reconstruction objects are flipped in sign.
The reconstructed objects use cm as units. In the display_JSON scene, the detector has been scaled so that the arbitrary distance units Unity uses are in meters. The reconstructed objects are therefore simply converted in the DrawParticleSpacePoints.js to meters.
The DrawParticleSpacePoints.js script currently draws space points. No UI is currently implemented that will allow a user to change what's drawn.
