[osg-users] WGS-84 osgTerrain

Hello again, and a good day to you.

We use a lo-fi earth model generated by osgdem. When we do a terrain
intersection, then convert to a 0-altitude coordinate, the location we
get is inaccurate due to the fact that the model's geometry is an
approximation of the shape of the earth. Is there a way to use
osgTerrain to find the intersection of a vector with a WGS-84 earth?

Thanks,
John
