Behind the Scenes: The Chemical Brothers ‘Wide Open’A survey at the process from The Mill shows how they put together the latest video for the Chemical Brothers directed by Dom&Nic,using 3D scanning and rendering to produce that ‘how the hell did they achieve that convincingly’ transparent one shot effect:… Teaming
up with Efficacy4D, we captured
a LIDAR scan of the set and then used the scan to ensure that we had a very
accurate track. Matching the dancer would’ve been a whole lot harder whether we
couldn’t trust the camera track. We used the scan to project HDRI images
for accurate lighting, or which was also incredibly useful for making clean
plates.… By far the most labour intensive fraction of the project was the 3D tracking (matchmoving). Our team of animators had to position each limb so that it precisely matched Sonoya’s pose on all 6798 frames. This is one of the most complicated things that we achieve in VFX and is a highly intricate and skilled job. How did we overcome this? Patience,lots of patience.
Not only was this the longest shot we enjoy ever tracked, we incorporated a range of new procedural modelling techniques, and human body scanning,lidar scanning, motion capture, and an extremely complex rig,animated lighting, cloth simulation and a huge amount of cleanup work. These combined added up to an extremely complex blend of techniques.
