I wanted to add a multiuser mode oriented to allow competitions. Searching around I have found OpenSim.<br>
<br>I have being asking about this in the chat channel and basically OpenSim lacks and needs to accommodate this kind of simulator at least the following:<br><br>- realistic physic simulation (IMHO <a href="http://www.adrianboeing.com/pal/index.html" target="_blank">http://www.adrianboeing.com/pal/index.html</a> is the way to go)</blockquote>
<div><br>we have the ODE as one of the physics engines. I guess one could implement more engines, but I personally think that a greater stability with a few is better than "somewhat working" but too many. <br> </div>

I think we were not focusing on that so far, but a good thought on that area would be useful, imho.<br>

<div><br>I think all of these could be implemented as modules - so you do not affect the "general population" if the functionality is of limited use to all. On the other hand, you expose the potential of your technology to a potentially large base.<br>

Also, it seems that OpenViewer is in an early stage of development. Some of those changes would need support from the client. </blockquote><div><br>Speaking of the animating the avatar - I was thinking that since the animations are quite small in nature, it might be possible to have a "continuous stream of small animations" to allow the precise control over the movement of the avatar in-world. <br>
