3D, 3D Tech

Hmmm … its a 2D Arri Alexa camera with two small 2K cameras, one on either side of the main camera. Does it shoot 3D? Not exactly. The two extra cameras are used to capture depth information for later post processing and conversion of the original 2D video into a converted 3D representation.

The advantage of doing 3D this way – versus shooting true 3D to start with – is that in post production you can create some 3D depth perspectives that are difficult to do in true stereoscopic 3D shooting. As I mentioned previously, the 3D conversion of Top Gun had a few scenes featuring good 3D depth from near to quite distant – which is difficult to do with a paired camera. (The lens spacing needs to be narrow for close in shots, but narrow spacing reduces the depth effect as you move further away from the camera).

Speaking at TV Connect in London, [HBO CTO] Zitter claimed that 3D TV that used glasses is dead and admitted that he is very sceptical over whether consumers will ever buy 4K televisions.

A multi-directional wide-angle 3D display system

A multi-directional backlight for a wide-angle, glasses-free three-dimensional display : Nature : Nature Publishing Group.

When I was at CES, I suggested to someone that I cannot name the idea that perhaps it would be possible to create multiple steerable viewports from a display. How that would be done is way past me but the idea is similar to the original idea for Vivato Wireless’ flat panel Wi-Fi antenna. That antenna concept, in its original incarnation, could steer multiple Wi-Fi beams simultaneously from one antenna. The flat panel used an electronically steerable phased-array concept to create several directional beams. Suppose there were 3 users out in a field – the antenna could create a directional beam independently yet simultaneously to each of the 3 users.

If we can do this at radio frequencies, I thought, perhaps there is a way to do this at optical frequencies.

The description of this HP invention sounds similar (but could also be completely different). Their invention demonstrates glasses free, full color 3D displays.
