VirtualPlanetBuilder does the equivalent as an offline build. Neither projects handles add 3D models, and certainly not forests. At present I don't know of any 3rd party open source forest NodeKits. This may happen in the future but there is no near term prospect I'm aware of. There are commercial solutions for rendering of forests though which you could look into.

Re: [osg-users] dynamic QuadTree on spherical terrain
Torben, The next version of osgEarth will have a new Features framework that supports the creation of 3D geometry from vector/GIS data. This includes draping vector data (already in svn head); extruding vector footprints, placing external models, flat road integration, and point-model substitution (placing a model at the location of each point in a vector file). Forests would fall into the last category.

Re: [osg-users] dynamic QuadTree on spherical terrain
Hi Art and Jason, Thanks for your answers, very interesting paper, and Jason you're absolutly right, osgEarth is the answer :) Eric -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16735#16735 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] dynamic QuadTree on spherical terrain
Hi all, I used a lot databases made with osgdem on spherical terrain. I'm wondering if there is something existing in osgTerrain to manage dynamic quadtree on such databases (I'm talking about geometry only) ? It could be a very good starting point to implement GPU CLOD texture algorithms to improve terrain rendering, avoiding huge geometry data on disk when working with elevations... Does anybody heard about such a project ?

Re: [osg-users] dynamic QuadTree on spherical terrain
Hi Eric, there is a fresh paper about that, what you want to do: http://wwwcg.in.tum.de/Research/Publications/TerrainRayCasting Oh at least, I think this is what you want to do?

Re: [osg-users] dynamic QuadTree on spherical terrain
Hi Eric, Are you talking about being able to generate the quadtree on the fly rather than preprocessing it? If so, then check out osgEarth ( http://www.osgearth.org), that's what it was made for :) Thanks, Jason On Tue, Aug 25, 2009 at 12:55 PM, Art Tevs arti_t...@yahoo.de wrote: Hi Eric, there is a fresh paper about that, what you want to do: http://wwwcg.in.tum.de/Research/Publications/TerrainRayCasting Oh at least, I think this is what you want to do?
