A project back from 2012. My job was: on-set assistance, New York shot (for example at 00:28 or 1:53) - 3d modelling, camera mapping, camera animation, fog (done with Particular in this shot). I also did some simulations and rendering of volumetrics for other shots (FumeFX, 3dsmax).
The amazing detailed matte painting used for projection was created by Przemysław "Traśnik" Czapla. You can find him here:
