3D Movies at Home!
While the previous page covered movie and theatre release considerations, DIGIDIA also touched upon the 3D home move status since HDTV is fast becoming a norm in homes and the next step moving forward is to bring the 3D experience home. The slide below illustrates the technology adopted by major TV and projector manufactures for their current and upcoming line-up of 3D-ready displays.
As you would have noted from the slide, the active electronic shutter glasses based technology is going to be the choice of 3D experience at home just like those used in NVIDIA's own PC-based 3D Vision kit. As we spoke to NVIDIA engineers, they mentioned that while Autostereo 3D TVs and display technology are available which doesn't require the glasses, but the industry is more concerned of the 3D experience which the electronic shutter glasses based technology can provide unrestricted, Full HD video quality experience much better than any other current forms at a reasonable price point. Plus, one has to consider that not all content is in 3D and as such the display has to double as a good 2D display as well - Autostereo 3D displays don't excel at this and are best suited for 3D signage than for the home.
3D displays on the small screen are however easy to implement due to the very small display size and the extremely limited viewing angle. 3D can be implemented by using a 'Parallax Barrier' method where each eye sees only a certain view and the combined view as processed by our brain will perceive it to be a 3D display with depth.
The biggest problem in 3D for the home is that display sizes can vary by a great degree and accommodating content for a 20-inch multimedia screen all the way up to a 103-inch plasma monster is no joke; without proper compensation, the 3D effect may not be effective, thus spoiling the fun altogether. This screen size differential would mean adjustments to the interocular distance (the stereo spatial distance between both eyes) would have to be compensated for and here again the GPU can play a role to perform real-time adjustments with regards to screen and room size.
