Hi,
I’m afraid I cannot connect to that website, there is some problem with certificates, or unsafe Java, or something.
From the User Guide:
Force Reporting
The joint may be configured to report each frame the force that was required to hold it together. To enable this behavior, set the joint’s reporting flag. The force may then be retrieved after simulation with a call to getForce():
joint->setConstraintFlag(PxConstraintFlag::eREPORTING)
…
scene->fetchResults(…)
joint->getgetConstraint().getForce(force, torque);
The force is resolved at the origin of actor1’s joint frame.
Note that this force is only updated while the joint’s actors are awake.
