Re: [osg-users] why transform nodes give a big impact to cull time??
Matrix-matrix concatenation, probably. And if you're changing them dynamically, then bounding box recalculation also.

Re: [osg-users] blender exporter question
Hi Simone, The best way should be to update osgART component to work with the last version of osg. I remember that a version of the exporter worked with osg-2.8 but the code (in exporter and osgAnimation contains bugs). I remember that some patch related to osgAnimation have been backported to the last release of osg-2.8.2 so I think you could have a try with this version and try if osgART works with it. In this case you could use the last exporter I think. If you want to try different version of osgexport You can install mercurial get the repository with a specific revision. I dont have time to check with more details right now. Have a try with osg-2.8.2 and tell me if it works for you Cheers, Cedric On Fri, 2010-08-13 at 10:51 +0200, Simone Mangano wrote: > Hi Cedric, > I have a question about your blender exporter to osg format. > I'm developing an augmented reality application and want to display > some animated models that uses bones animations like for example > avatar.osg example in the osg data folder. > I exported succesfully an example that works with osganimationviewer > in osg 2.9.8 but unfortunately with this version of osg I'm having > problems with the osgART library I'm using to connect with artoolkit. > > By the way I can use 2.8 version of the openscenegraph lib but the > models I'm exporting seems not to work, some models results not > coplete and some others doesn't display nothing, I imagine that the > current version of exporter uses an osg format that don't work with > 2.8. > > Is there a way to download an old version of the exportar to use for > the 2.8 version? > > thanks a lot > Simone Mangano > -- Provide OpenGL, WebGL and OpenSceneGraph services +33 659 598 614 Cedric Pinson mailto:cedric.pin...@plopbyte.net http://www.plopbyte.net signature.asc Description: This is a digitally signed message part ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [ANN] osgPango / osgCairo
Hi Jeremy, Thanks you and your donator for this work, we're also planning to mostly use osgPango instead of osgText in our company, so I'll probably make you some feedback as soon as I have time to take a look to this new version.

Re: [osg-users] [vpb] Height retrieval from dted file
Hi,
This is regarding my earlier post.
The file that generated is geo-referenced.Using osgpick, i could see the
lat,lon and some z value.
for ex.:
(76.3396,32.292,0.0260343) using osgpick.
i have used ConvertXYZtolatlonheight, but i get some values, which is
incorrect. The code is
.
osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode;
csn->setEllipsoidModel(new osg::EllipsoidModel());
csn->addChild(myModel); //this is pointing to .ive file
os<<" local coords vertex("<< hitr->getLocalIntersectPoint()<<")"getEllipsoidModel()->convertXYZToLatLongHeight(point.x(),point.y(),point.z(),latitude,longitude,height);
latitude = osg::RadiansToDegrees(latitude);
longitude = osg::RadiansToDegrees(longitude);
os<<" lat,long,height("<< latitude << "," << longitude << "," << height << ")"
