The scripts that were used in the exploding wall video are now available at our gitHub repo (link below). I invite you to download and test them on your servers. If you see ways to optimize or better leverage the existing physics capabilities of open sim, please feel free to submit updates or discuss code changes.

We are a methodical group and a couple months ago I asked one of our interns to work with the developers to create a series of baseline physics behavior case studies. The first case study is a destructible wall caused by an explosive charge. This wall is composed of blocks that are tested at a high density and a low density to simulate different destruction effects. The goal here is to eventually have all of the prims in the sim loaded with the scripts needed to react to any type of random explosive charge set by the participants in the training scenario. The video can be found below: https://youtu.be/jSofWcwWi7g Your feedback is welcome. Observations: 1) Current limitations of the open simulator prevent us from expanding the tests beyond a simple wall. 2) The scripts exercise the engine well and expose limitations between the sim frame rate and the physics frame rate. 3) It is easy to crash the sim with this demonstration, especially if more than a handful of people are present (more than 3-4 client connections).
