ATI Has Announced Its Open Stereo 3D Initiative at GDC 2010

March 11th, 2010 · 15 Comments · General 3D News


More interesting news coming from GDC 2010 in San Francisco, this time from ATI announcing their Open Stereo 3D Initiative in trying to work with more partners to ensure support for multiple different stereoscopic 3D solutions (learning that thanks to MTBS3D, not from ATI!). The idea of the open initiative is to offer consumers additional choices when selecting an S3D solution, more innovations and of course help in lowering the costs for the hardware and software making it easier for wider adoption. ATI (AMD) and its partners will supposedly soon announce a lineup of 3D products, including a 3D-enabled ATI Eyefinity technology (to counter Nvidia’s 3D Vision Surround), 120Hz 3D-ready displays and notebooks, active shutter glasses and passive polarized ones (have you heard of passive shutter glasses!?), S3D support for DirectX 9, 10 and 11, Quad Buffered OpenGL, Blu-ray 3D support. As you can see from the presentation slide above the 3D-gaming middleware partners are DDD and iZ3D, and for Blu-ray 3D support ArcSoft and CyberLink. ATI is also going to try to work on establishing standards that will help in having compatibility and much wider choices when building your computer and stereo 3D setup if they are adopted by others. The only thing that still remains to be seen is how soon we are going to see actual products on the market as ATI has been talking about S3D support for quite some time, but still no dates when to expect it are available… although we have multiple hints about summer availability. But being so open I still don’t see ATI joining the S-3D Gaming Alliance like two of their major partners that will make stereo 3D gaming possible on ATI GPUs (iZ3D and DDD) or any other association that is trying to openly promote stereoscopic 3D technologies?! But for that matter Nvidia is also not a member of S3DGA or any other similar independent organizations, as far as I know…

ATI’s Stereoscopic 3D Plans Will Start With Catalyst 10.3

February 23rd, 2010 · 4 Comments · General 3D News


The above slide is from recent AMD/ATI presentation regarding their upcoming Stereoscopic 3D support for 120Hz displays and the new Catalyst 10.3 drivers due to be released in March. The slide mentions only iZ3D as a middleware partner by name, but suggests that others will also be supported (DDD for example), but don’t get your hopes too high yet. The Bit Cauldron shutter glasses, the ones that are supposed to go along with this solution, should be available around the summer and iZ3D haven’t released a new beta of the driver for quite some time. So things are slowly moving for ATI and the reason for that is that they decided to go for more open solution, but they have more external factors to take into account partnering with other companies to provide the complete solution. iZ3D’s driver currently can work on both Nvidia and ATI hardware, but their shutter glasses support is still in beta and is not problem free – looses sync when the framerate drops below the refresh rate. So with a new version of the driver and all other pieces in place, with Catalys 10.3 or newer being part of all that, we can hope to have an alternative solution that will support ATI’s GPUs for stereoscopic 3D gaming, photos and videos on a 120Hz LCD display in a few months. And as for 120Hz displays there are already quite a few with more expected to be available by the summer and we all expect to have 120Hz capable HDTVs from most major consumer electronics players by that time too. So things will definitely be very HOT this summer regarding S3D and not only…

22-inch iZ3D Stereoscopic 3D Monitor is Now Available for Testing

22-inch-iz3d-s3d-setup


I’ve been planning to get one of the iZ3D 3D Displays for quite some time now, but it turned to be quite a problem to actually purchase one and get it delivered from Europe and not USA. Anyway, the good news is that thanks to iZ3D now I have a 22-inch iZ3D Stereoscopic 3D Monitor available for reviewing games and testing, so expect to see more about it on the blog it very soon. You can also expect more game reviews, profiles, tweaks, guides and so on not only for 3D Vision, but for iZ3D too… that is provided if I manage to get enough time dedicated to doing all of these. But let me tell you about the iZ3D monitor a bit more and why it is so interesting compared to other solutions already available.

iZ3D has a different approach than what other passive polarized solutions offer at the moment and this has its own advantages and disadvantages. One of the most important advantages of the two LCD panels approach of iZ3D is the fact that you get full resolution image as opposed to just half horizontal resolution with the other passive products. Instead of having one panel and passive polarization filter in front of it to separate the screen in even and odd lines horizontally with different polarization, the iZ3D solution uses two separate LCD panels. The back LCD panel sets the brightness of the pixel and the front ones sets the right polarization. Then, based on the different polarization the 3D glasses route part of the light to the left eye and the remaining light goes to the right eye, so that you get full resolution stereoscopic 3D image. The disadvantage of that approach is that there might be more ghosting, but then again the amount of ghosting can be influenced by different factors and iZ3D is constantly trying to improve things. A recent example for that was the release of updated passive polarized glasses that do improve the results quite a bit compared to the first generation of glasses.

Of course I should also mention that the iZ3D driver has support for both Nvidia and ATI-based video cards, so you should be able to play in stereoscopic 3D no matter what your GPU is based on, provided that it is not too old or is too slow in terms of performance to handle S3D gaming.
