More 3D Displays to Come 122

Posted by michael from the invest-in-dramamine dept.
Anonymous Writer writes "The first laptop using an autostereo display to show images in 3D without special glasses was the Sharp Mebius PC-RD3D in Japan, later released in the US as the Sharp Actius RD3D. NEC has a line of computers with autostereo displays as well. They are the NEC Valuestar T VT900/8D desktop, the LaVie S LS900/9E laptop, and LaVie RX LR700/8E laptop. The line uses NEC's SoundVu technology that uses the display as a speaker! Autostereo displays are becoming more popular according to Martyn Williams and Tom Krazit from the IDG News Service. In their article in PC World, they claim laptops are just the start of it. A new satellite service by Mobile Broadcasting will be broadcasting 3D content to handheld devices in Japan some time soon. Another player in this market is Dynamic Digital Depth (mentioned in a previous post of mine), whose content services convert 2D video to 3D for display in this medium. Sanyo may be releasing 50-inch Plasma Displays that can display 3D. MIT's Media Laboratory is developing a more advanced 3D display, calling it a full resolution autostereoscopic display, that would allow a viewer to walk around and not lose the 3D effect, which current autostereo displays can't do."

It renders two frames, one intended for each, and somehow informs the goggles which one to show to which eye.

      Figured since I'm a 3D artist, you wouldn't mind if I chimed in. Would a stereoscopic display help me? If the display is convincing enough, yes! Right now, while I'm modelling, I'm constantly rotating the model around, sometimes just slightly, just to get a sense of the parallax. This gives me a clue as to what vertices are where. A stereo display could potentially relieve me from needing to rotate it as much. If that's true, I could get more detail on the screen without worrying about the vid card not being powerful enough for what I'm doing.

    I'm trying to wrap my mind around what exactly that convoluted mess of an MIT press release [mit.edu] is trying to say. If I understand correctly, and someone please correct me if I'm wrong, the system tracks the heads of the people surrounding the display, then projects left-eye right-eye information through an adjustable polarized filter and lense system so that the viewable angle only includes the intended eye.

    I imagine that the effective viewing angle on these planar 3D displays is very restrictive; move a couple inches to either side and all you'll end up seeing is the half-resolution image meant for one eye.

    The "3D displays to come" that hold the most promise, however, will require that you wear (non-dorky) viewing glasses. These normal looking glasses will use a safe Retinal Scanning [mvis.com] laser to directly overlay 3D imagery onto your field of view. Of course, we won't see this tech in BestBuy until the Law of Accelerating Returns [kurzweilai.net] has run the course of a few more years.

      CAD usually end up hitting system resources much harder than games, since games are designed to only render datasets that will provide acceptable performance on the target hardware, while CAD programs, by their very nature, can attempt to render models of arbitrary complexity. Furthermore, with an arbitrary CAD model, you can't get performance boosts from precalculated optimizations like BSP trees.

      Also, speaking as someone who spends much of the workday turning 2D CAD files into 3D models, I don't think a 3D display would really be that useful in CAD, except maybe for client presentations. For starters, leveraging a 3D display to full usefulness would require a good 3D input device, and those just haven't arrived.

      Furthermore, given the limited number of scanlines, It would seem you'd be restricted to a fairly low number of pixels (depth-xels?) of Z resolution, which could quickly become a problem with fine detail.
