2d3, together with Vicon and Geospatial Vision, is part of the Oxford Metrics Group, which provides computer imaging systems for the entertainment, defence, life science and engineering industries.
The Boujou software, which runs on multiple computer operating systems, automatically captures camera tracking and calibration data for the easy combination of live action with 3D graphics.
The software is also used for games development, architectural visualisation and industrial design projects.
Tim Catchpole of Double Negative said Boujou was used in most sequences of the Stardust film, especially highly detailed shots like the Sky Vessel and Witches Lair sequences.
"When we applied Boujou to a suitable shot, it was frequently a time saver. There is one shot where the Sky Vessel appears to land on water, which can be notoriously difficult to track," said Catchpole.
