A 3D Production Guide for 3D Television Production by 3net

February 18th, 2012 · 1 Comment · Shooting in 3D


The 3D television production studio and 3D TV channel 3net along with its partners Discovery, Sony and IMAX have released a comprehensive manual for stereoscopic 3D pre-production, 3D workflows, 3D post-processing and delivery of high-quality 3D television programs. The 3D Production Guide features stereoscopic expertise from the top producers and technical advisors from the channel and its partners and the good thing is that it has been made freely available for everyone interested in it in the form of a PDF file. The 50-page illustrated manual includes detailed information garnered from the combined 50 years of experience in the area of 3D from those who contributed to its creation. The guide outlines in detail all of the facets involved in creating top-quality 3D content for television, from initial workflow planning, to production, post production, stereographic correction and final delivery.

The 3D Production Guide is a document outlining current best practices in the area of 3D production for television. It is the result of extensive contributions from the 3D experts of 3net’s partner companies Discovery Communications, Sony Corporation and IMAX Corporation. The guide was authored by Bert Collins, Josh Derby, Bruce Dorbin, Don Ecklund, Buzz Hays, Jim Houston, George Joblove and Spencer Stephens, with Bert Collins and Josh Derby serving as editors. It will be constantly updated and amended as the dynamics of 3D television production continue to evolve. And while this manual has been developed for 3D TV production most of the things found in it can be helpful and useful for any stereoscopic 3D enthusiast or professional, so it is something definitely worth reading.

3D Vision Best Practices Guide by Nvidia for Software Developers

October 17th, 2010 · No Comments · GeForce 3D Vision


Nvidia has released a best practices guide for software developers that is intended to help them deliver the best possible stereoscopic 3D experience to their users. The guide contains an overview of how the automatic 3D Vision technology fits into existing technology stacks, common problems that arise when using the solution for automatically providing stereoscopic 3D mode in games, and most importantly how to easily work around those issues. It is not that hard to make sure that the software you are working on, being a game or other 3D application, is going to be rendered correctly when displayed on a 2D surface such as a computer screen or projector or being shown on a stereo 3D capable display. And why not to devote some attention to the most common issues that people that already play games in stereo 3D mode on their PC do hate to see in new titles and this is making them not want to buy a game, just because it is not working well in stereoscopic 3D mode. Of course Nvidia is not the only player in the stereo 3D market for PCs, but their 3D Vision technology is still the most popular one and quite a lot of their recommendations to avoid certain potential problems do apply for other solutions as well.

Game developers are already starting to see the potential that stereo 3D gaming can bring and are slowly going in that direction, but besides titles that are specially worked on to ensure good 3D compatibility or to provide native stereo 3D support, still for most other games there is no attention whatsoever dedicated to ensuring that they can be comfortably played in stereo 3D mode. Nobody is talking to have them completely issue free as this also may require additional testing and development meaning more time to market, but by following some basic principles and not going through the “shortcuts” in making things faster or easier, just because nobody will notice in 2D does not mean that it will be the same when you play the game in stereo 3D mode… or at least when you try to. So if you take care of the basic stuff to ensure lets say good compatibility with the automatic stereo 3D solutions for PC gaming, then later on you can release patches to improve things for the constantly growing stereo 3D community by also getting feedback from them. This process of learning on the go from each other may help a lot in speeding and widening the adoption of 3D technology as well as getting more and better 3D content, so does it sound like a win-win situation to you? And as it is said “Content is King”, however 3D content is still lacking behind the big amounts of different 3D-capable hardware base that is constantly increasing and things should go hand in hand. But enough rambling on that, if you are interested in what tips Nvidia has for the developers wanting to ensure compatibility with 3D Vision you can check the guide in PDF format. You can also take a look at another new guide, also intended for developers, that is covering some specifics regarding the more recent Nvidia Surround technology that users three monitor or projectors in 2D or stereo 3D mode to provide bigger visual workspace which can lead to better productivity or more imemersive gaming.

Using Anaglyph Glasses with 3D Vision Driver

June 22nd, 2009 · 29 Comments · Anaglyph Glasses

cp-enable-stereoscopic-3d


With the 3D Vision drivers you get a nice bonus, or at least you may call it like that, because apart you’ll also get free support for anaglyph 3D stereo mode. Or said with simpler words you’ll be able to play with a depth perception using your normal computer system and a pair of anaglyph (those plain old red/cyan paper or plastic) glasses. Of course using the anaglyph mode will not provide the same impressive and great looking depth perception in games and 3D applications, but will give you a nice upgrade when gaming, because you’ll be able to at least have some 3D effect. The requirements that the anaglyph mode has to you is to own a pair of anaglyph glasses and it seems Nvidia will start offering some of these very soon, but you can also get them from other places pretty cheap. The only other thing you’ll need is an Nvidia-based videocard, preferably a faster one that can provide enough frames for comfortable playing. There is no limit to the supported GPUs as when using the 3D Vision shutter glasses, and also there is no need to have a special 120Hz display, because anaglyph mode can work just fine with your normal CRT or LCD monitor. Just have in mind that the 3D Vision drivers require you to be using Windows Vista or Windows 7 in order to function, because they are not available for Windows XP! So why don’t you install the latest video drivers version 186.18 and the 3D Vision drivers included in the package and try the anaglyph 3D mode…

Here is a quick setup guide:
1. Open “Nvidia Control Panel” in Standard or Advanced mode.
2. Select “Stereoscopic 3D” and choose “Set up stereoscopic 3D”.
3. Click on the checkbox called “Enable stereoscopic 3D” in the main panel.
4. A new window will open, where you need to click on the button labeled Next.
5. Put a tick in the checkbox celled “Enable 3D Vision Discover” and click on the Next.
6. You’ll see a message saying no compatible 3D display is found, again click on Next.
7. Now you have to put on your anaglyph glasses and pass the test you’ll be provided with.
8. A new test is being displayed to verify if you are actually seeing depth on a special image.
9. Finally you can see some 3D stereo demo images if everything is fine, but you can as well skip this step.
10. If you’ve passed the two tests everything is ok and you can start playing games in 3D Stereo using your anaglyph glasses.

By default you have set a depth value of 15% which should be Ok for a start, but you’ll probably want to be able to adjust it during gameplay to achieve the best possible perception of depth. If you’ve had GeForce 3D Vision there is a hardware button to easily change the depth percentage, but here you’ll have to do it with a key combination. Another thing that you should know is how to activate and deactivate the anaglyph 3D mode with a key combination, because by default when you run a 3D application it will be automatically activated. If you don’t want that check the Hide stereoscopic 3D effects when game stars in drivers’ control panel. Then when you want the 3D mode turned on you need to just press CTRL + T and then a second time to disable the anaglyph mode so your game will be back to normal. The other useful key combinations are CTRL + F3 to decrease level of depth and CTRL + F4 to increase it, of course there are more kay combinations, but I’ll discuss them later on in a separate topic. This should be just enough to get you started in playing games with anaglyph glasses with a pretty nice 3D effect, although you’ll notice that you have some problems with color reproduction, but that is normal when using anaglyph glasses so don’t worry…

Aside from the color reproduction and perception you might notice one other thing that is also completely normal after using anaglyph glasses so don’t freak out if/when that happens. If you haven’t used anaglyph glasses up until now when you wear them for some time and take them off your vision will be a bit strange for a while. And if you close one of your eyes you’ll either see a hotter image (more reddish) or a colder one (more bluish)… as I told you it is normal and a few minutes later everything will be back to normal. This happens because your eyes adjust with the different color filters the anaglyph glasses use and even when you take them off there is some time needed for them to revert to normal. ;)
