Re: [osg-users] Improving this scene frame rate
Can anyone help me? If I'm using hardware instancing to use the same geometry in different nodes with the same skeleton too, what is the correct method to call computeMatrixPaletteUniform function? Because geom.getMatrixFromSkeletonToGeometry() is giving me identity matrix all the time...

Re: [osg-users] Camera default stateset ???
Hi Nick, osg::Camera is just an Node so to set the state that you want to get inherited to everything below it you simple do: osg::StateSet* ss = camera-getOrCreateStateSet(); ss-set*(); Robert.

Re: [osg-users] Lagging between main camera MV and prerender camera
Hi all I solved the problem! Actually the mistake I made is that the uniform holding the texture-matrix was added to the stateset of the root node. Instead I had to dive into the ShadowedScene, find the stateset of the shadow receiving scene part and add the matrix (and the prerendered texture) there. Now everything is working fine...

Re: [osg-users] Any way to optimize the performance of massive osg::Text?
Hi Lv, To scale to 100 of thousands of text labels you'd need to come up with a custom implementation. osgText was never written to scale to that level, and to do so in a general purpose class is not viable. It's not in any way possible to actually read that many text labels so one has to ask at what point do you plan of simplifying it so the user can actually read what is going on screen. For you application I believe you should work out exactly what high level behaviour you want for your text labels - how they are aligned, blended with the terrain, how they interact with each other, now they get LOD'd out and in, how you might page the data if required, how many labels you'd want on screen at one time. Once you have all this behaviour set then you start designing an approach that can meet all of these requirements. Robert.

Re: [osg-users] Any way to optimize the performance of massive osg::Text?
I was having mainly memory issues when I created lots of text objects. I did not run into such bad performance issues. Are you sure you're testing a release build and not a debug binary? Suggestion: Only create these text objects when these enter the viewing frustrum, and destroy these again when they leave it.

[osg-users] CPPDepend free license for OpenSource Projects
Hi Folks Robert, I've just found this interesting offer: http://www.cppdepend.com/CppDependfoross.aspx They claim, that an open source project such as OSG could get a free pro-license after application. Maybe it is of interest for OSG sihce it might improve stability among other things.
