Open Simulator with Physics Engine

Has anybody looked at this for the XO? http://opensimulator.org/wiki/PhysicsEngines The physics is not very realistic yet. Presumably we could manage simple statics and dynamics, with graphs of position, velocity, and acceleration. I would like to have a simulation engine available for integrati

I have played with PyODE, but not on the XO. http:// pyode.sourceforge.net/ I suspect that the XO would not be able to handle a realistic 3D simulation with a large number of objects. This is partially due to the lack of GL for rendering. Simpler things, like wireframe rendering, 2D simula

Hi I saw this some time ago: http://www.youtube.com/watch?v=d7eGypGOlOc It's called Physics Illustrator. I know, it is developed by Microsoft but still it's really cool. Source code is available at: http://research.microsoft.com/research/downloads/Details/aeee3085-a219-47d6-88fc-a2501f00800d/Det

Hi, Just wanted to chip in with a thought of a simpler activity sim type that could be a low hanging fruit to port or code for the XO. I do love the idea of 'crayon physics' and all the other physics sim spinoffs that are all the fashion just now, but a lot of fun/ exploration can be had wi

It is not something done with a physics engine, but there are a few particle systems written in Etoys. For example, if you launch Etoys, click on "Gallery of Projects", and click on the thumbnail third from the left in the bottom row. It is an ideal gas simulation (in 2D). You can modify the
