How to take in-game 3D Stereo screenshots in JPS format

June 20th, 2009 · 3 Comments · GeForce 3D Vision

While you are playing a game or using a 3D program compatible with GeForce 3D Vision you can take screenshots in JPS format that can be viewed later on in a 3D form instead of the normal “flat” 2D screenshots that can be saved on JPEG format. If you press the Print Screen button or use a program like FRAPS to take in-game screenshots when using GeForce 3D Vision you’ll notice that only normal (single frame) images are being saved. But if you press ALT + F1 instead while in the game you can save a JPS screenshot that actually contains 2 images – one for the left eye and one for the right, thus allowing you to see the image in 3D Stereo mode with a compatible viewer. The 3D screenshots are being saved in a folder called NVStereoscopic3D.IMG in your current user’s My Documents folder. The only drawback when taking 3D Stereo screenshots is that it takes some time, when you press the key combination to save a JPS file you may have to wait for a second until it is ready…


By default when you install the GeForce 3D Vision drivers you also get the Nvidia 3D Vision Photo Viewer that is needed in order for you to be able to open JPS files and view them in 3D Stereo mode. When you open an image in full screen it is shown in 3D mode, and when you exit the full screen mode it gets in a side by side view of the two frames (the ones for the left and for the right eye). You should have in mind that when viewing the 3D stereo images you cannot change their level of depth like you can in a normal 3D application… when making the screenshots they are being saved in the depth level you were using in the actual game or other 3D application.

How to Watch 3D Stereo Movies with GeForce 3D Vision

June 20th, 2009 · 12 Comments · 3D Movies & Videos, GeForce 3D Vision


You should know that GeForce 3D Vision is not only intended to be used just for gaming, but also for watching 3D Stereo digital images and even for 3D movies. But in order to use the shutter glasses for watching moves you should first get a special player that can play 3D stereo movies the right way and they you should get movies that are supported. Nvidia provides a free Stereoscopic 3D Video Player that should be more than enough to get you started in the world of 3D movies, but there are also some other solutions that I’m going to talk about some other time. Nivida’s Stereoscopic 3D Video Player has built in support for playing back 3D Stereo videos in the following file formats: AVI, AVIS, WMV, WMVS, ASF, MPG, MPGS, MPEG, M1V, MP2, M2TS, VOB, MP4, SVI and SPP. There is also support for playing 3D Stereo movies in DVD Video format if you own any of these of course and they are in the right format. And by the right format I mean movies that are not encoded for anaglyph viewing, but provide a video with two full separate frames for each eye. You should know that most of the DVD video 3D movies are designed for paper anaglyph glasses and these will not work with the shutter glasses form the GeForce 3D Vision kit!


To get you started there are some short videos in 3D Stereo that are looking quite well when played with the Stereoscopic 3D Video Player and the GeForce 3D Vision kit. There are 6 short movies, two of which are animated and the other 4 are of different real world scenes and places so you can actually see the difference. You can also look around over the net for more compatible videos, these should be quite a few more that will look and work great with the added depth perception. Have in mind that all those videos can be viewed in normal 2D mode on a normal or 3D-compatible monitor and in 3D Stereo only on a compatible display. When you run the player and a movie on a Samsung 2233RZ for instance when you switch to full screen the movies automatically goes in 3D mode, otherwise when it is being displayed in a small window it is in 2D mode by default.

Cooliris with Official 3D Vision Support

June 20th, 2009 · 1 Comment · GeForce 3D Vision


Cooliris is an interesting plugin that transforms your browser (Internet Explorer, Firefox or Safari) into a lightning fast, cinematic way to enjoy photos and videos from the Web or stored on your computer in a cool new way. The program allows you to view 2D images and videos only (so far) with an intuitive and very cool looking 3D interface, and now you can turn the browsing experience into an even more fun experience with the perception of real depth with the help of nVidia’s GeForce 3D Vision kit. There is already a profile in the latest driver version 186.18 that provides pretty good results in Cooliris, but not perfect. The program also has support for viewing JPS and PNS format 3D stereo images, but 3D videos support will be even more impressive and that may be possible in a later version, but who knows. Anyway nVidia rates Cooliris’ 3D Stereo results as good with a notice that some objects render at wrong depth, but overall the results you’ll get are very satisfying and it is a good improvement especially if you are a frequent Cooliris user. Have in mind that Cooliris 1.10 might not work if using older 3D Vision drivers, I haven’t tried that, because I’ve read that the latest drivers are required and I’m using them. ;)

Download Cooliris version 1.10 with 3D Vision support…
