Hi Paul, Thanks for the info.
The reason I ask is because my company is investigating doing snow plowing. So we are wondering if dynamically deleting and adding vertices is possible in real-time, or do we choose switch nodes, or dynamic texturing. Is Phase III a possibility to this SBIR? Thanks.

Hi Zach -- Phase II of this SBIR is near completion; the last deliverable is the OSG Quick Start Guide documentation that I'm feverishly trying to wrap up. All the software is complete at this time. We call this software "real-time" because it deforms the terrain during load from disk. There is of course some non-zero cost associated with this deformation, but since most terrain databases load terrain tiles in a background thread (like the OSG database pager) the extra cost to modify the terrain isn't noticeable. If you were to use this software for something like snow plowing, the deformation cost might be more noticeable. I imagine there might be some "low-hanging fruit" optimizations that would help. Another issue is that the software is currently implemented as an OSG plugin, obtaining input as unprocessed terrain from disk. For the use cases you mentioned, the software would need to be modified to reprocess an existing scene graph, accumulating multiple deformations. This would be a minor change. As currently implemented, the software uses a Gaussian blur as the deformation filter to create "hills" or "valleys" as needed to fit the elevations of target models. The filter could be changed so that the deformation takes the form of a crater, as long as you can express that deformation procedurally. If you have other questions regarding this project, don't hesitate to ask.
