Stereo
VFX elements were an important part of the process in converting effects such as holograms and Scarlet Witch’s magic, for which the team used up to 12 layers of elements for each shot. For the transition out of the scene in which a young Tony Stark is seen in a holographic display, the stereo team worked with VFX vendor Animal Logic, creating stereo cameras for the VFX house to allow them to stereo render the hologram layers for the converted scene – a technique that Stereo team developed during its stereo conversion work on ‘Gravity’.
The stereo team delivered stereo conversion for 53 minutes of the runtime. The team used geometry for each of the main characters’ heads from cyber-scans of the actors, or if these weren’t available, creating their own geometry from supplied references. For characters like Black Panther, who has a CG suit, the team was able to take z-depths from the VFX vendors to ensure accuracy and consistency in the stereo.
