One thing I don’t understand with this. Why 2 scripts in each and
every brick? Why not simply make the bricks physical and apply an
external force from the explosion. Script overhead in opensim is
rather high and this approach introduces a fair bit of script
overhead in addition to running the physics simulation itself.<br>

<p>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. </p>

<p>Good Morning, as you all know the MOSES
developers are working on PhysX integration
into the Open Simulator to support
functionality currently not possible in the
platform. 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. </p>
<p> </p>
<p>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.</p>
<p> </p>
<p>The video can be found below:</p>

<p><a moz-do-not-send="true"
href="https://youtu.be/jSofWcwWi7g"
target="_blank">https://youtu.be/jSofWcwWi7g</a></p>
<p> </p>
<p>Your feedback is welcome.</p>
<p> </p>
<p>Observations:</p>
<p>1) Current limitations of the open simulator
prevent us from expanding the tests beyond a
simple wall.</p>
<p>2) The scripts exercise the engine well and
expose limitations between the sim frame rate
and the physics frame rate.</p>
<p>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).</p>
