Post-production technologies like visual effects (VFX) or digital grading are essential for visual storytelling in today's movie production. Tremendous efforts are made to seamlessly integrate computer generated (CG) elements into live action plates, to refine looks and to provide various delivery formats such as Stereo 3D (S3D). Thus, additional tools to assist and improve element integration, grading and S3D techniques could ease complicated, time consuming, manual and costly processes. Geometric data like depth information is a key for these tasks but a typical main unit camera shoot does not deliver this information.
