My thesis was Dynamic Terrain (DT) some 15 years ago at Central Florida. I was a GRA at The Institute for Simulation and Training (IST). We were under contract to STRICOM to prototype a system for corps engineers to train on berms and crater soil management. We used a spline surface server to manage the terrain. Our underlying soil model picked up and processed DIS terrain packets and updated the spline server. The visuals subscribed to the spline server for modified areas (axially aligned) then re-tesselated in real-time. This was in the days of Performer before flux buffers (i.e., frame-to-frame data propogation). The internal scenegraph was static in topology, but the underlying geometry actually triple buffered and numericlly moved as it was retesselated. This allowed for DT as well as Continuous Level of Detail (CTLOD). Unfortunately, I ran out of time to do some form of smoothing. Hence, the crater and soil settling visually popped from one state to the next as new data was processed. I believe Jenny Zhao had subsequently developed a form of DT in Performer. This would be good to look at.
