Title:
- Directable Stadium Crowds from Image Based Modelling for “Bohemian Rhapsody”
Presenter(s)/Author(s):
Abstract:
To deliver photoreal, dynamic and directable rock concert audiences for “Bohemian Rhapsody” to a demanding client brief, lead VFX vendor DNEG developed a novel crowd simulation solution based on multi-view video capture and image based modeling. Over 350 choreographed performances by individual crowd extras, totalling more than 70 hours of footage, was acquired on set using a video camera array. A system was developed to convert the video data to lightweight 3D sprites that could be quickly laid out, synchronised, edited and rendered on a large scale. Efficient artist workflow tools and scalable video processing technology was developed so that crew with little previous experience in crowd simulation could fill a virtual Wembley Stadium with a dancing, cheering crowd responding to Freddie Mercury’s electrifying performance.
