Bit Cauldron to Offer Alternative to Nvidia’s 3D Vision Shutter Glasses

January 7th, 2010 · 14 Comments · Other S3D Tech


I’m sure you probably haven’t heard about the company Bit Cauldron, I sure haven’t up until recently. It is a relatively new company that is just starting to be mentioned regarding the exponentially increasing interest around Stereoscopic 3D everything. Bit Cauldron was formed in November 2008 to focus purely on enabling a world-class 3D experience at home by addressing multiple critical gaps in the 3D ecosystem. The three founders of the company are quite interesting with Sam Caldwell, VP of Engineering at Bit Cauldron that is also founder of a ZigBee RF/ID company, with ZigBee being the wireless radio communication technology that is being used by Bit Cauldron’s products. Bit Cauldron has an advisory board, also made up of quite interesting people, including guys like Geoff Phillips, ATI Vice President and General Manager of the Digital Television Business Unit. I’m mentioning ATI as it seems that Bit Cauldron and their first product in the form of active shutter glasses for stereoscopic 3D support will be used by ATI for providing a complete Sterescopic 3D solution to be used with ATI cards. This will however require you to have a high refresh rate display – one of the new 120Hz LCDs for instance, along with additional software that will be able to provide the stereoscopic 3D content to the display such as iZ3D’s driver.


Currently there are two types of shutter glasses being listed on the company’s website and these are: BC3000 DLP Link 3D Glasses and BC5000 Radio Frequency 3D Glasses. The first one – BC3000 is designed to be used with 3D HDTVs or 3D-ready projectors that utilize DLP Link technology with the glasses having a built in DLP Link receiver. The second product – BC5000 is designed to be used with 3D-Ready computer displays, these glasses incorporate an IEEE 802.15.4-2003 (ZigBee radio) transceiver for communicating with the computer (using USB connector) or again with a 3D HDTV incorporating a VESA 1997.11 standard stereoscopic connector. One thing to note regarding the BC5000 glasses is that they seem to be designed for usage with ATI GPUs as the official website mentions on the product page that there are: Transmitters available for 3D-Ready TVs and PCs with AMD GPUs. So this might as well be what ATI has been referring to Stereoscopic 3D support available for their current line of Radeon HD 5xxx series GPUs.

A USB transmitter can attach the BC5000 shutter glasses to an Advanced Micro Devices’ GPU to create the word’s best 3D experience for 3D Blu-ray movie viewing and Gaming.

The BC5000 3D Glasses achieve their 3D Synchronization using Radio Frequency Technology (the ZigBee radio) which is claimed to offer: no line-of-sight interferences, no infra-red remote control interference, no florescent light and sunlight interference – things that might sometimes create problems to solutions that use IR (infrared) transmitter for synchronization like 3D Vision for example. Bit Cauldron’s synchronization technology is also claimed to eliminate ghosting with multi-microsecond accuracy, offer adjustable duty cycle for multiple display types and provide glass lenses that have clearer and brighter picture. The lenses of the glasses should offer multi-frequency 50/100Hz, 60/120Hz, 84 Hz operation and be even 240 Hz display ready, which is something that still needs to be verified when the true high Hz TV sets hit the market later this year (3D Vision glasses should also be compatible with these). The battery inside the BC5000 3D Glasses is a rechargeable Lithium Polymer one that can be recharged over a micro USB connector up to 500 times with each full charge providing at up to 60 hours of use.


Bit Cauldron states that their shutter glasses are available only under private labels and to OEM’s, meaning that you won’t be able to get it directly from them, but buy it with your video card for instance or branded with another name. Most likely ATI will offer these as a kit with a suitable display to complement a stereoscopic 3D solution that will work on PCs with ATI video cards, but we’ll have to wait and see along with checking of the shutter glasses are as good as Bit Cauldron claims they are. Also these shutter glasses are expected to be more affordable than other alternatives, but there is still no word on what the prices will be. Another thing to not is the fact that if they will rely on iZ3D’s Driver is the fact that the latest software still has only beta shutter support that is having issues with syncing the signal, so we’ll also need new driver. So don’t wait to see these right away available on the market, but I’ll try to keep you updated as I’m quite interested in how will things develop…

Using Acer Aspire 3D Laptop with iZ3D Driver Instead of TriDef Ignition

January 3rd, 2010 · No Comments · Other S3D Tech


If you are an owner of Acer Aspire 3D AS-5738DG laptop you should know that this mobile computer uses DDD’s TriDef software to provide Stereoscopic 3D support for pictures, video and games, but since it is using a Horizontal Interlaced mode to create the stereoscopic 3D effect you can also use other software. This made me try the Aspire 3D laptop with iZ3D’s driver instead of the bundled TriDef software just to be sure and to check if there will be any significant difference when using one or the other software. You should know that both TriDef Igniton and iZ3D Driver still do not support DirectX 10, although both are working on adding this support and we should have it pretty soon, and as for DX11 it is still too early.


When you install the iZ3D driver you need to setup it to use Interlaced, Horizontal (optimized) mode in order to have it working as it should with the Aspire 3D laptop. You can as well use the normal Horizontal mode, but the Optimized version is supposed to provide a little bit of improvement by doing some minimal vertical anti-aliasing as opposed to just skipping the unneeded lines in normal mode, although the difference it is hardly visible and there seems not to be any significant difference in terms of performance.

The next step was to try a game that is not completely problem free when played in stereoscopic 3D mode and to measure the performance difference by using both programs to see if any of them is better. The game I choose was X-Blades, because it looks quite good in S3D mode and is not too heavy so the Radeon 4570 video card in the Acer laptop could handle it. But at the same time X-Blades also has an issue when HDR is enabled and you try to play in stereoscopic 3D mode that becomes apparent when you move the camera with the mouse around your character. It turned out that the weird “wash out” effect is present with HDR enabled on both iZ3D and TriDef Ignition and then again the performance I got from both solutions was pretty close to each other. When playing X-Blades in normal mode, at maximum details, with no AA at 1368×768 resolution I get average of about 40 fps, but when switching to stereoscopic 3D mode with the help of iZ3D or TriDef Ignition the framerate on both goes to an average of 24 frames per second. There is just a slight difference if you turn the Autofocus function of the iZ3D driver On, resulting in about 2-3 fps drop. Have in mind that these results were achieved with PowerPlay disabled for getting the top performance from the laptop as I described here Optimizing your Aspire 3D Laptop for Best Performance in S3D Mode. The end result from the comparison between the programs that allow you to turn a normal 3D game into a stereoscopic 3D game is that they perform pretty much on par with each other in terms of quality, performance and even features. Of course each of these solutions has its own small advantages, but if you’ve bought an Acer Aspire 3D laptop there is no reason for you to additionally buy a license for iZ3D Driver as you won’t get a significant improvement at this moment. When iZ3D Driver version 2.0 comes out things might get improved, but also don’t forget that DDD’s TriDef is also being updated quite frequently and you can upgrade your Acer Aspire 3D laptop with latest TriDef software for free.

About the HDMI 1.4 Standard and the Stereoscopic 3D Support

December 29th, 2009 · 3 Comments · Other S3D Tech


The HDMI 1.4 specifications were introduced earlier this year, but we are yet to see devices using the new standard and taking advantage of the new features that were introduced, one of which is the official stereoscopic 3D support. Aside from that HDMI 1.4 increases the maximum supported resolution to 4K (4096×2160 pixels), new HDMI Ethernet Channel with speed of up to 100 Mbps, Audio Return Channel, new Micro HDMI Connector, expanded support for different color spaces and an Automotive Connection System.

Of course the thing you are probably most interested in is the stereoscopic 3D support that is expected to be the key factor into making the 3D support widely available on TV sets and other consumer electronic devices, including game consoles. The HDMI 1.4 specifications support wide range of 3D display formats at up to 1080p resolution, including: frame, line, or field alternative methods; side by side methods (full and half) and 2D plus depth methods. And as 3D video requires substantial data throughput, you’ll have to use a High Speed HDMI cable that can be even an HDMI 1.3 compatible, although with such you’ll not be able to use the new Ethernet Connection feature.

Here comes an interesting question that is related to PlayStation 3 – how will Sony add stereoscopic 3D support for the console that only supports HDMI 1.3? The truth is that even HDMI 1.3 is capable to provide enough bandwidth for 120Hz video output even at 1080p resolution, but the actual problem might be in the console not being capable to support 120 frames per second in Full HD resolution. So it is most likely that stereoscopic 3D gaming on PS3 will start of at 720p resolution, especially if Sony will want their consoles to be able to work on 200/240Hz displays providing enough fps for good experience. Anyway these are still some thoughts about the issue and are not based on official information coming from Sony, so we should still wait a bit more to see what will actually happen. It is also quite possible that the firmware update fore the PS3 that will add the S3D support won’t add support for gaming in stereoscopic 3D for all the already released games and we’ll have to wait for new titles. Another thing that is also still not quite clear regarding the PlayStation 3 is the support for the recently finalized Blu-ray 3D specifications and the upcoming Full HD movies on Blu-ray next year. The PS3 should also be able to play 1080p videos in 3D, but we are yet to see how thing will turn out…
