Well, another 6 month gap, but a lot of new features. My focus right now is entirely on my PhD - nearly every new feature here has been added on its account. Ignoring bug fixes, of which there have been a fair few, the new features, that I can think of, are:

Note: You can now get 64 bit versions from the panda 3d website - starting from 1.5.3. Saves me the effort of compiling them:-)
Not sure how this happened but I seem to be doing 64 bit versions of Panda 3D. Well, I guess I want them, so it makes sense to share. Anyway:
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.

Well, its been over six months since the last update. 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've finally had a paper published, so thought I better put it up. 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 [PDF].
Poster of above [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.

Note: Since this post I've done the same thing to panda 1.5.0, the deb for gutsy gibbon of which may be found here. 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 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.)

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 thought I'ld stick it up.
