Re: [osg-users] KdTree issue...
HI Shayne, The stack trace suggests an allocation issue when building a KdTree leaf. Any chance you are running out of memory? As a general comment I would suggest that you try OSG-3.0.1 rather than a old 2.9.x developer release as there is chance that bug fixes will have fixed bugs that are relevant to you. If moving to OSG-3.0.1 doesn't fix the issue then I would work on isolate which tile causes the KdTree builder to crash, to do this I'd write out each tile to a .osg(t) file prior to doing the KdTree build so if it crashes you have a record of the problem tile and can then test it stand alone.

The only catch is that DTED uses an EGM96 vertical datum. osgEarth supports this, but cannot automatically read that information from the GDAL driver; so, you have to manually tell osgEarth about it by overriding the profile for your elevation layer like so: ... http://forum.osgearth.org/ Good luck!

Re: [osg-users] OSG Serialization - changes on custom Classes
Hi Peter, I've just submitted a patch which adds user version to the serializers. Could you please have a look at it in the osg-submissions archive and test if it could work for your cases?

Re: [osg-users] [ANN] osgRecipes: Integrate OSG with almost everything, the second wave
Thanks Michael, As the libRocket integration is already implemented in the dtEntity project (code.google.com/p/dtentity), I'd love to make use of the existing one and avoid re-inviting wheels unless I myself just have different demands of the same library. So that's why I exclude libRocket from my TODO list, neither do Cairo, Pango, OpenAL, etc. Maybe you could have a look at dtEntity's implementation first and see if it could satisfy you and others. :-) Thank you, Wang Rui 2012/8/24 michael kapelko > Good work! > I'm not sure if I voted for libRocket, so here it is. > ___ > osg-users mailing list > osg-users@lists.openscenegraph.org > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Thanks Frank. I'm downloading the new SDKs now, and will have a look at them as soon as possible. Wang Rui 2012/8/24 Frank Kane > Happy to see our stuff on the list!

Re: [osg-users] Possibility of an OSG bot
I don't understand what I'm doing wrong. Here's what my Infovisitor outputs: osg:Node:Group osg:Node:Group db osg:Node:OcclusionQueryNode OQNode_0 osg:Node:Group TableChairs osg:MatrixTransform:MatrixTransform osg:Node:ProxyNode osg:Node:Group db osg:Node:Group Chair1_84 osg:Geode:Geode p3004 osg:Drawable:Geometry osg:Drawable:Geometry osg:Geode:Geode p1077 osg:Drawable:Geometry osg:MatrixTrnasform:Matrixtransform osg:Node:ProxyNode osg:Node:Group db osg:Node:Group Chair1_84 osg:Geode:Geode p3004 osg:Drawable:Geometry osg:Drawable:Geometry osg:Geode:Geode p1077 osg:Drawable:Geometry ...another 2 times, for a total of 4 Chair1_84s. using the polytope intersector, I collect the hits into a group but use grp->containsNode(hit) to avoid the ~5000+ hits because all I'm interested is how many (logical) objects there are visible in the scene. I thought I might be able to store the matrixtransform in the group node, getting 4 different matrixtransforms but that's not the case. I see 4 chairs on my screen, but can only find one distinct node. Why? How can all 4 chairs I see on the screen all reference the same matrixtransform?

hi! yes, i have managed to build the examples that come with it, and other people managed to do so too. you shouldn't need to change anything in the example source code, in fact if you follow my tutorial to the dot then you should be able to have it working in 1/2 to 1h. i'm sorry to say that i don't know a solution to the error you're getting. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49539#49539 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
