Well, I guess I want them, so it makes sense to share. Anyway: panda3d_1.5.1-ubuntugutsy_x86_64.deb (http://www.thaines.net/content/panda3d/panda3d_1.5.1-ubuntugutsy_x86_64.deb) (Note: I've now tested the above under Hardy Heron - it works fine.) Be warned that no sound or video playback (ffmpeg) support is available, as these have yet to be ported to 64 bit.

First there was the thing alluded to in the last post, then I broke my arm (Badly, like multiple fractures and a whole load of metal badly.) and now I'm in the last year of my PhD, which makes time something of a commodity. This weekend has proved free however and I thought I'd spend some of it polishing Cyclops just enough to do another release.

I had to do a poster session, so I've also put up the poster; this is mainly because unlike the actual paper I had space for a diagram showing data flow, which makes things marginally easier to understand. As a quick summary the paper is dealing with the combining of stereopsis and shape from shading, using Gaussian belief propagation for the core component. Its rather esoteric, and the approach as a whole is not exactly simple. But the core algorithm and ideas are not that hard really - I don't think a simpler working approach to this problem is that likely. Of course, the usefulness is rather limited as its constrained by the limitations of both approaches, but it is (I hope) a small but valid step to something actually useful. Integrating Stereo with Shape-from-Shading derived Orientation Information (http://www.thaines.net/content/research/2007_BMVC.pdf) [PDF]. Poster of above (http://www.thaines.net/content/research/2007_BMVC_Poster.pdf) [PDF]. It may be found in the British Machine Vision Conference 2007, Vol. 2, pp 910-919. The BMVC website will also have a copy, incase there is a problem with my website.

This time the changes should make it into the cvs repository, so in the future 64 bit users should be able to compile it themselves. I might continue to provide .deb files if the panda site does not however. Panda 3D (http://www.panda3d.org) is a rather nice game making tool I use, mostly for messing around. Problem is there is no 64 bit version, nor has anyone converted it. (There about half way between being an open source project and a closed source one. Its a bit strange, source is available, but under a silly license. More critically they don't have the OS development spirit - there might as well be a wall between the community and the developers. Still a dam good piece of software, just needs to have its wings fully unpinned.) Programming - Panda 3D Wed, 18 Jul 2007 15:06:07 +0100 http://thaines.net/content/view/60/15/ I was trying to explain the above data structure to my brother, after concluding that instant messaging is not the best communication medium I gave up and drew a diagram instead. I have no idea if it has actually helped his brain get a handle on it, but as it could be of some use to someone else I though I'ld stick it up.
