How do I remove air resistance?

I have a space simulation, so obviously I don't want gravity or air resistance. Gravity was straight forward to turn off, but I can't find the equivalent for air resistance. I presume it's going to be on a body-by-body basis rather than a world wide setting like gravity.

Indeed I see on btSoftBody that there are values for medium density like air_density but I am using btRigidBody.

Solution

  • There is no air resistance in bullet physics but there is damping

    For every body you create you should set damping calling 

    body->setDamping(linear, angular);

    set linear to be 0
