Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

As I try more cases I'll be able to get a better sense of the speed differences and if I do any systematic tests I'll report back. My main concern at this point is whether I'll be able to use my existing nodevisitors on objects such as trees that are clamped onto osgEarth. My existing code is

Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

Ethan, The answer to that question (accessing the tree node) depends on how you're getting it into the scene (there are several ways). If you are using marker-substitution with clustering on, your tree model will be deconstructed and optimized -- you won't be able to get to individual tree nodes

[osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

I had been building terrain complexes using osgdem using both the -d and -t flags to combine elevation and textures. This works great when I have relatively low resolution. I am now running into scenarios where I am using 1 meter lidar elevation data and want the maximum number of levels.

Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

Thanks Chris, I actually compile osgEarth and osgGIS last week and played around with them a bit thinking I may go in that direction. I was having trouble getting the vpb driver to work properly and the osgEarth vpb driver page even says: If at all possible, you should run osgEarth against the

Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

I think the best thing then is for me to get my scenarios up and running with osgEarth and see just how much a speed hit I'd take using it vs VPB. Plus the project I'm working on may ultimately be better served by hosting the data on a server and creating a web interface for the user, and
