NVIDIA Accelerates the Search For a Cure

Back in August of last year, at the NVISION visual computing conference in San Jose, NVIDIA publicly demonstrated some new stereoscopic 3D technology. While stereoscopic 3D in and of itself is not new, the devices on display at NVISION were, and featured new hardware, monitors, wireless glasses, and software. At the event, the technology was demoed on a Mitsubishi 73-inch 3D Ready 1080p-capable DLP television and new ViewSonic 120Hz LCD monitors using a number of popular games. We got the chance to play a few games ourselves back then and watched some others play as well, and thought the effect was excellent.

Fast forward to today, and NVIDIA is ready to officially take the wraps off of their stereoscopic 3D technology, which is now known as GeForce 3D Vision. NVIDIA's GeForce 3D Vision product consists of a pair of wireless, rechargeable glasses, a base station / IR transmitter, and the necessary software and cables to connect the device to a PC. However, it needs some other specific hardware to function properly as well--namely a compatible monitor and graphics card.

The specifications and main features of NVIDIA's new GeForce 3D Vision glasses are posted below, but we've got many more details on the pages ahead. Take a look...

As you can see, the system requirements for GeForce 3D Vision are not very high--a modern dual-core processor, 1GB of RAM, and Windows Vista are necessary, along with a compatible GeForce graphics card in the GeForce 8- 9- or GTX200-series. Finding a compatible monitor is a different story though. Any CRT capable of a 100Hz refresh rate (or higher) will work, as will a number of 3D capable HD televisions and projector. As for LCD monitors, only certain, true 120Hz capable displays will work.

>> "taking the wraps off of their stereoscopic 3D technology"

So, the patent on the Sega Master System 3D Glasses must have finally expired, eh?

Nope. nVidia had 3D glasses available at the time of the very first GeForce branded cards. The chief complaint about them was always that they cut the screen refresh rate in half. These do the exact same thing, but nVidia danced around it by only making it work with monitors with rather obscene refresh rates.

The old glasses worked off the Z-buffer and thus required minimal extra processing, I'm sure the new process is quite similar though I have yet to see specifics. I think the pricing and the fact that it works with very few monitors will conspire to make this a pretty low seller.

I was jokingly pointing out that this "new immersive technology from NVIDIA" i.e. "_their_ stereoscopic 3D technology" had been in use for 20+ years.

The z-buffer doesn't really have anything to do with the 3D effect. The z-buffer is used to determine if new pixels will be drawn or if they're behind objects already in a scene. nVidia's technique probably requires 2 of them, since they're duplicating every rendering surface created by the application. The 3D effect is entirely the result of rendering the object from two slightly different camera positions.

There's beauty in the way they did this in the driver to offset the D3D camera position left and right of where the game/software says it should be on every other render, but it hardly seems like a technological breakthrough.

I'll bet if you don't get perfect framerates, the visuals go to hell with tearing super-quick. They probably have the software flip to the other view whether the current one has been completely drawn or not.

A minimum forced framerate? That'd be kinda cute, actually. It's interestig to note as well that the problem I noted with lower refresh rate monitors was always that the imaged "flickered" when using the glass since 60 mHz refresh turned into 30 with the glasses on. I wonder if it does anything to the perception of frame rates. Normally you need around 40-50fps for it to appear really smooth, would it need to be higher with the glasses?

My point with the z-buffer comment was that determining depth isn't really difficult since the video card does it anyway. Switching the perspective back and forth shouldn't result in a large amount of overhead, so there shouldn't be much of any performance hit. Certainly not the likes of enabling AA or AF anyway.

The Elsa 3D glasses were a shade over $100 back in the day IIRC. If these come down to the same price point I might have to check them out.

i have Samsung LCD but its not 3D monitor, but i ll converted it with my Geforce graphis card,now i m using Discover glasses for 3d , but i wish 2 use these nvidia 3d goggle with IR Emmiter, & my graphics card shw setting for that too....., can i used my LCD moniter for 3D ( Samsung 18.5' inch, SyncMaster B1930) ..because my LCD monitor have only 2 slot, 1 for power supply & other for connection with cpu........please tell me ,hw can i use NVidia 3D vision glasses
