Ethan, VPB is typically used for creating statically built pre-runtime databases. osgEarth is more of a dynamic model and paradigm. I would use either one or the other depending upon your needs. Based on what you want to do, I agree with Chris that osgEarth would probably be the better fit.

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 original source data instead of using this driver. You will get better performance with suffer fewer headaches. " Are you suggesting replacing VPB with osgEarth entirely for my needs vs generating a VPB terrain file and combining it with osgEarth?

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. This takes hours to generate, but I may be looking at the same area over and over. However, the texture that I wrap onto that same are will be changing. Do I need to run osgdem for each texture? As far as I can see in the documentation there isn't any way to add texture to an existing osgdem-generated terrain complex; am I wrong? I know that for each level, osgdem is breaking up the original texture and doing level of detail wrappings for it, so maybe it is impossible. I may end up digging into the source code for osgdem to see what can be done but wanted to pose this question to the forum to see if anyone has any ideas about whether this can be done already or how feasible it is > > > to > > > do this by changing the existing source code.
