Is there any way to get stable contact points of objects?

Post by keeeeeeep »

I' making hybrid control test program using bullet physics.
I want to get contact points between two objects , and I made program using tick callback along following URL.
http://bulletphysics.org/mediawiki-1.5. ... _Callbacks

I could get contact points , but the contact points are unstable.
For instance ,when I press dynamic box to static wall, they repeat collision between On and Off like chattering.
I want to stable contact points. Is there any way to get stable contact points of objects?

I thought the collision threshold is the key , so I changed margin by colShape->setMargin function , but nothing changed.
And I tried to use setContactProcessingThreshold function. When I set minus value , contact points became a little stable, but I can't understand the reason,
and that isn't sufficient.

Best regards .

I would like to know the answer to this also having observed the same: that setContactProcessingThreshold makes very little difference.
