I think loading meshes for use as physical proxies would be possible if it were a simple format, such as ".obj". There would need to be some kind of constraints on the mesh such as limits to the features that the file formats can use, and limits to the number of vertices and triangles so as to not use too much server memory or collision calculation time. Another issue is the storage and retrieval of mesh assets. I dont think we have a simple way for the sim to retrieve mesh assets with the current asset databases that are implemented.<div>

This is just a "me too" message with regard to Hypergrid and ODE, and a<br>
general mesh question in part (3).<br>
<br>
(1) Hypergrid<br>
<br>
I've been experimenting around with Hypergrid, and this has a real<br>
potential for laying<br>
the virtual groundwork for world cross-linkage and small community<br>
building -- something missing. The problem of<br>
<a href="https://jira.secondlife.com/browse/SVC-2941" target="_blank">https://jira.secondlife.com/browse/SVC-2941</a> is<br>
significant since one has to know, ahead of time, where grids locate themselves,<br>
but hopefully that will be fixed. In the mean time, having this part<br>
of the release<br>
seems really good. In a release incorporating the hypergrid, would there be<br>
an opensim.ini (rather than the current approach using a command line option)?<br>
<br>
(2) ODE<br>
<br>
We have done some small robot work here using OpenGL, OGRE, and ODE so<br>
having this capability in OpenSim seems to make a lot of sense. I<br>
suppose there is<br>
always the issue of server load (where ODE is running) but that can be<br>
at the discretion<br>
of the server admin.<br>
<br>
(3) Mesh Loads<br>
<br>
Do you think it possible to employ an osl function for loading an arbitrary mesh<br>
(similar to what is attempting to be done in RealXtend) ? I've looked<br>
through some<br>
of the code in meshmerizer, and while this was a cursory inspection,<br>
all of the prims<br>
seem to be already based on meshes, suggesting that to allow arbitrary<br>
mesh loads<br>
could be straightforward. Thoughts?<br>
