Hi Skylark, I have the 3d model of the object I want to place on the terrain and yes I'm also using VPB for creating 3D terrain. So my problem was mainly about placing the model on the tarrain so that it sits on the surface and not half over and half under.
So I looked at the osgIntersection in the examples that come with the source. But I found it awfully confusing and had a lot of code that I couldn't connect with the intersection part of the problem dealing with here. In terms of steps to follow for placing a model on a 3d terrain, I thought it would be something like: 1) Get intersector for the 3d model (model->getIntersector) 2) Use this intersector to check with the 3d surface (not sure which function here) 3) Get the osg::Vec3d of the intersection point. Use that vec3d in the PAT for the 3d model. Is this a logical track?
