Subject: | RE: ARtoolkit stereo viewing ? | ||
Hi Chris and Daniel, Thanks for you replies, we will give it a try, and see, I guess..... I will post our experiences later about the XP64 platform. Next question is: How to get a real stereo view, we would like to set-up two cameras, both registering the view of each eye, and use both of them keeping track of the markers ? We then send the views to a 3D HMD, one for each eye. We are wondering if we could do the tracking with just one camera? Or is it easier to let them both track ? Is this the way to do it ? Are there any other things to consider? We don't want to re-invent,so please feel free to share your experience with us ! Bye for now, Jackie -----Original Message----- From: Daniel Wagner [mailto:daniel@i ...............] Sent: Tuesday, June 20, 2006 11:38 AM To: Jackie Schooleman Subject: Re: ARtoolkit (plus) and Windows XP 64 ?

We just tested ARToolKitPlus 2.1.0 under Suse Linux 10.0 64-bit. Running the simple example that comes with ARToolKitPlus returned correct results for the pose matrix. While this is only a very minimal test i'd say it is good to give it a try... bye, Daniel |

We have successfully run ARTK on 64 bit linux (PowerPC and i386), and I can't see any reason why it wouldn't work on 64 bit Windows. However, I haven't compiled DSVideoLib on 64 bit XP, and that may be a roadblock. The VideoLinuxV4L driver includes some i386 assembly, but this can be turned off in favour of vanilla C if necessary. Stereo support is rudimentary in ARToolKit v2, and as Daniel has suggested, it is simpler to treat the two eyes as two separate views at first. You can quite readily adapt the twoView sample code in ARToolKit to this purpose. Should anyone really crave it, much more complete stereo support, including reduced error in pose estimation from combining the poses from both views, is provided in the commercially licensed ARToolKit v4.
