Dr. Andrew Hogue Explains the BF3 3D Research Tournament

August 30th, 2012 · No Comments · General 3D News


Dr. Andrew Hogue is an assistant Professor at the University of Ontario Institute of Technology as well as a Project Director in the iGo3D initiative. In the interview above he explains what iGO3D initiative is as well as talks about what the Battlefield 3 3D research tournament they’ve held at the Fan Expo 2012 a few days ago. Dr. Andrew Hogue also shares some other interesting things about stereoscopic 3D technology, so do take a few minutes to watch the full interview and I cannot wait to see what interesting findings and conclusions will be reached as a result of the BF3 3D research that was done by iGO3D at Fan Expo 2012…

What Gamers at Fan Expo 2012 Think About Stereo 3D Gaming

August 27th, 2012 · No Comments · General 3D News


The Fan Expo in Canada is now over and it is time to see some interesting coverage from it in 3D along with what gamers actually think about gaming in stereo 3D and especially playing Battlefield 3 in 3D. Neil Shneider from MTBS3D has some interesting interviews to share and the first one you can see embedded above with more to come in the next few days. The Battlefield 3 competition organized at the iGO3D booth, partly intended for research purposes, and of course to have some fun and give the ability to gamers to experience stereoscopic 3D gaming apparently was also a big success, and hopefully the results from the survey of gamers about their experiences playing the game in 3D would also be interesting. Now the interesting question is why we are not seeing more such researches being made at big events such as trade shows and conventions, giving people the ability to experience stereo 3D content and then providing a short survey where they can share their feedback. Such things can help a lot companies that are already providing some kind of stereoscopic 3D capable products or are interested in that segment, companies such as game developers, hardware manufacturers etc. can really benefit from that…

Console Commands For 3D Convergence Adjustment in Battlefield 3

December 8th, 2011 · 11 Comments · Stereo 3D Games


The latest patch for the game Battlefield 3 apparently has some interesting new extras regarding the stereoscopic 3D support in the game, including new console commands allowing the users to finally tweak the convergence level. Thanks to the users Chiz and GordyMeow over at the Nvidia forums who reported the following console commands and have verified that they are working…

The console commands are:

renderdevice.stereoconvergencescale <float32>: this controls normal convergence settings (default is 1), the higher your depth setting, the lower you’ll be able to set this before things start splitting in the near field, like your gun. Small value increments go a long way here, I could set this to about 2 at max depth before my gun started splitting too far.
renderdevice.stereosoldierzoomconvergencescale <float32>: this controls how much convergence for your gun and crosshairs while in ADS only. I set this value to 0 (default is 1) and RDS/Holo was accurate even for distant objects with Convergence set from 2-3 and set to MAX depth.

just hit the tilde key ` next to 1 on your keyboard and start typing “render” and the console has a predictive input system that narrows down the cvars for you. Correct syntax is: renderdevice.stereoconvergencescale 2.4345

Once you find settings you like and want to keep, you’ll want to create a cfg file so your settings are loaded automatically.

– Go to your BF3.exe directory, probably something like %\\Origin Games\Battlefield 3
– Right-click, New > Text document. Name it User.cfg
– Open it up with notepad, add the two command line settings below and save:

renderdevice.stereoconvergencescale 1.6 <----- change that value to whatever you like and remove this comment in your file. renderdevice.stereosoldierzoomconvergencescale 0

You are welcome to try their findings and report what values for the two console commands for convergence adjustment work best for you. Just don’t forget that you need the latest Battlefield 3 patch installed for these to work, the one released on 6/12…
