Lagrangian Particle Tracking
 

Hello,

I'm working on lagrangian particle tracking and I need to do a few things:

1. Use cloud function "particleTracks" to track a single particle of the cloud.
2. Transform the barycentric coordinates in positions file (of the form: (0.259168 0.186854 0.183562 0.370416) 12162 23944 2 ) to cartesian coordinates, or at least tell me what every component means
   

thank you in advance
