Re: [osg-users] COLLADA animation can't be resaved as .OSG
Hi Chris, Your first assumption is not true, if the loader colllada or another loader use custom UpdateCallback (from the their loader) and those UpdateCallback do not define code to save/load, then if you save it it will skip the custom update callback from the loader. It could why it does not work as you expect. But if you are saving to osgb and it works when you reload it, I would bet that some .osg code is not up to date to save stuff loaded by the collada, It would need more investigation to tell what's happen. I hope it gives you some idea where to look.

I'm curious, if we are able to load an animated model from a COLLADA .DAE and have it display ok in osganimate, then we SHOULD be able to resave and re-load that via .OSG format and have it still animate, correct? We're seeing it fail to animate, but saving to .osgb seems to work better. Is this how it is supposed to be?

Re: [osg-users] COLLADA animation in OSG file not animating in osganimationviewer
Hi, Chris try converting to osgb (i've had similar issue when converting fbx models), also you can try to set OSG_OPTIMIZER="OFF" just in case.Cheers28.04.2012, 01:43, "Chris Hanson" xe...@alphapixel.com: OSG 3.x, Windows, 32-bit. A COLLADA format model loads and animates fine in osganimationviewer.exe. However, when converted to .OSG format using osgconv, it no longer seems to animate, though it seems to contain objects pertaining to animation. Any ideas what we did wrong?

Re: [osg-users] Collada Animation
Hello, The Web3D consortium has resurrected it's H-Anim working group. So, OSG powers that be, might want to keep tabs on that working group. This would possibly prevent many different skeletal standards among the Web3D / Collada / Scenegraph community. John F.

Not by OSG. The problem with COLLADA animations (which is actually a good thing in most respects), is that you can really animate *anything* in COLLADA (from transforms to material/shader parameters), so it's quite a bit of work to get animation working in a complete way. The other constructs not supported by the OSG loader are controllers, such as skins and morph targets. If your file contains these, you won't see them either. Most of the time geometry is attached to one or more skin controllers. The bones of the skin controller are then transformed, and the transforms are animated. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] collada animation?
Hi Abe and Robert, I asked this question earlier but somehow it got off topic to discussing osgCAL. With the osg exporter from blender ( http://projects.blender.org/projects/osgexport/) we were able to do simple animations(the kind you are describing I think) directly. For our testing, we exported a spinning cube that also took a helix type path through the scene and it came through in osg without any problems. My question though, as sounds like is yours, was if I used the collada exporter, would this same type of simple animation example come through? This would be much better since our in-house modeler use packages like maya and 3ds. On 10/1/07, Abe Stephens [EMAIL PROTECTED] wrote: Hi Robert, Right now I'm interested in rigid body animation along pre-predefined paths or based on constraints defined within the modeling tool. For example: A vehicle animated along a path such that its wheels rotate and steerable wheels turn. In blender this type of animation would consist of both IPO curves and animation constraints. Blender isn't a requirement, I'm just curious what the best tool chain ending in OSG would be.
