Notre Dame Brule

To rebuild Notre Dame de Paris, THE YARD mixed photogrammetry techniques and LIDAR scanning. Thanks to the CNRS, we were able to obtain the point cloud produced by Andrew Tallon, a pioneering art historian who sadly died on November 16, 2018.

All the fires were simulated with SideFX Houdini, using intensively a GPU accelerated sparse fluid solver called Axiom. So, sparse fluid simulations for fire and smoke, then used those to advect some particles for the embers and ashes.
