Re: [osg-users] Kinect(OpenNI) / Blender - Character / Animation
Hi Cedric,
by the version 2.59 it doesn't work. I install the the script and see the
entry, but I can not enable the addon.

(http://www.pic-upload.de/view-12504262/blender2_59.png.html)
By the Version 2.60a it works good.
Thanks.

Now I have two skeletons (blender, kinect) with different size.
How can I match this?
Or is it enough to copy the Rotation from the Bones?
In a simple test I create a funktion like this.
update(XnSkeletonJointTransformation jointT)
{
//fill Matrix with the value from jointT
::osg::Matrix mat(values);
Bone-setMatrix(mat);
}
Thank you!
Cheers,
Benjamin

[osg-users] Kinect(OpenNI) / Blender - Character / Animation
Hi at all and a happy new year. I want to animate a character in OSG with the Kinect(OpenNI). My idear was to create an character in Blender(2.59 / 2.6...) with a skeleton. But I am not sure how can I export this. I cant install the osgexporter. In an other topic from me (Problems with setInfluenceMap to RigGeometry) I used a little python script. This writes bonename, pointinex and weight in an txt file. Then I export the mesh as an OBJ-File. But I think this isn't a good way. Have anybody a better idear? Thank you!

Re: [osg-users] Kinect(OpenNI) / Blender - Character / Animation
Hi, The best would be to improve the osgexporter to support skinning correctly for blender 2.60.

Hi, maybe not a straightaway solution - but consider to reconstruct geometry from point cloud. there is one example code: http://tetgen.berlios.de/features.html http://www.cs.ubc.ca/labs/imager/tr/2009/eltopo/eltopo.html( see also links below ) this way you would be able to compute error metric from model to pixels and decide accordingly links: http://www.cs.ubc.ca/labs/imager/tr/2009/eltopo/eltopo.html http://www.cs.jhu.edu/~misha/Code/PoissonRecon/ - code (osg Based ) and paper http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Surface_reconstruction_points_3/Chapter_main.html ( http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Point_set_processing_3/Chapter_main.html#Section_56.7 http://www.cgal.org/Manual/latest/doc_html/cgal_manual/packages.html#Pkg:Triangulation3 http://www.cgal.org/Manual/latest/doc_html/cgal_manual/packages.html#Pkg:Triangulation3 http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Surface_mesher/Chapter_main.html ) papers http://www.geometry.caltech.edu/pubs/MDDCA10.pdf http://www.cs.jhu.edu/~bolitho/Research/PoissonSurfaceReconstruction/PoissonRecon.pdf the parallel variant http://www.cs.jhu.edu/~misha/MyPapers/ISVC09.pdf http://www.cs.jhu.edu/~misha/Fall05/Papers/ohtake03B.pdf http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.25.2726rep=rep1type=pdf additionaly • *GTSLibrary –* The GNU Triangulated Surface Library. http://gts.sourceforge.net/index.html • *VTK:* http://www.vtk.org/. • *Volume and Surface Meshing –* http://www.cse.ohio-state.edu/~tamaldey/mesh.htm. • *Poly2Tri:* An open source CDT library http://code.google.com/p/poly2tri/. • *Jonathan Shewchuk* - http://www.cs.berkeley.edu/~jrs/ http://www.cs.cmu.edu/~quake/robust.html Regards Sergey ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Yes, it's quite a poor test. I was actually only seeking to quantify the low end of the error, which is plainly visible as the thick band down in the 5 region. My code averages errors out down in this range, and throws errors out that are outside this range. There's a lot more work and testing that could be done in this space, but my client's application didn't really call for anything further. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

I would simplify the scene substantially; why not take a flat surface (a piece of foam board with know dimensions) and place it in an open space at a few known distances from the sensor? You can then also rotate the image plane about a couple estimated angles. Then plot errors perhaps as a function of distance vs. sqrt( angle_x^2 + angle_y^2), as a start. I would recommend that you take a look at a paper: Anderson, D., Herman, H., Kelly A., Experimental Characterization of Commercial Flash Ladar Devices, International Conference On Sensing, 2005. Yes, it is different technology but the error analysis used there I think would be relevant. cheers, t On Fri, Mar 4, 2011 at 12:03 PM, Chris 'Xenon' Hanson xe...@alphapixel.comwrote: I recently published some info I've learned about Kinect on my web page. http://xenon.arcticus.com/kinect-z-buffer-noise-and-audio-beam-steering-precision I'd like to talk to other OSG people who are using, or plan to use Kinect, and see what you're up to. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

Re: [osg-users] Kinect
Hi Chris, At present I'm working on an open source project named osgXI (http://osgxi.svn.sourceforge.net) with another Chinese engineer. He has already made some progress on the kinect support and upload some code to the osgInput namespace. The implementation initially depended on libUSB and then changed to openNI as far as I know. I myself have no idea of the kinect part (I worked out the Cg, CgFX and post-processing functionalities), but can act as a go-between if you have inerests and questions about the project and his work. Believe or not, he can speak or write too little English by himself. :-) Cheers, Wang Rui 2011/3/5 Chris 'Xenon' Hanson xe...@alphapixel.com: I recently published some info I've learned about Kinect on my web page. http://xenon.arcticus.com/kinect-z-buffer-noise-and-audio-beam-steering-precision I'd like to talk to other OSG people who are using, or plan to use Kinect, and see what you're up to. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
