Real time Chroma Keying in Stereoscopic 3D:
Here’s the dilemma: Productions are now all going stereoscopic 3D. (the word stereoscopic should suffice, but we add 3D to prevent ambiguity), and there is a need to preview a live chroma or green screen “key” in 3D, because compositing and match moving in S3D is a whole different beast, more challenging than doing the same in 2D.
Simple “foot contact” of actors, with the ground gets even more complicated to composite in S3D than it is in 2D. A bad S3D composite will show up as people floating off the surface of the ground. In 2D, without stereoscopic depth cues such problems are rare and [...]
