[ODE] mass ratio idea

[Jon Watte]

You can implement this in your nearcallback just fine. 
It works reasonably well, although you need to make sure 
that if the heavy object has high velocity, you add extra 
force to the baseball ball so it exits the collision with 
at least a velocity equal to the velocity of the train in 
the direction of the collision normal.

Cheers,

Subject: [ODE] mass ratio idea


Here's an idea for dealing with the problem of having
two objects collide with a huge mass ratio:

Whenever two objects (both with bodies) collide,
calculate the ratio of the larger mass to the smaller
mass.  If the ratio is above some threshold (e.g. the
large mass is a train car and the small mass is a
baseball), ignore one side of the collision.  In other
words, temporarily treat the train car as a static
object (with no body).

Any thoughts?
