[ODE] Simulating Magnetism...

Just use forces and collision. The magnet would draw other objects towards the center, somewhat proportional to the magnetic mass of the target object and the strength of the magnetism, and inversely proportional to the square of the distance between magnet and object center.

If, once the objects get glued together, you want to make simulation more efficient, and making it stick, you would remove the target body, and add its geom (using a geomtransform) to the list of geoms used by the big accumulating ball.

Subject: [ODE] Simulating Magnetism...

Has anyone here played the game Katamari Damacy ( 
http://www.namco.com/games/katamari_damacy/ ). Anyway basically I was 
wondering if it would be possible to use ODE to simulate a large 
spherical magnet.

How would others suggest I attach other objects to this magnet at 
runtime. Would creating a certain type of joint for each new object, be 
the way to go?
