class PxSphericalJoint : public PxJoint
A joint which behaves in a similar way to a ball and socket.
A spherical joint removes all linear degrees of freedom from two objects.
The position of the joint on each actor is specified by the origin of the body’s joint frame.
A spherical joint may have a cone limit, to restrict the motion to within a certain range. In addition, the bodies may be projected together if the distance between them exceeds a given threshold.
Projection, drive and limits are activated by setting the appropriate flags on the joint.

Public Functions
-
virtual PxJointLimitCone getLimitCone() const = 0
Set the limit cone.
If enabled, the limit cone will constrain the angular movement of the joint to lie within an elliptical cone.
See also
PxJointLimitCone setLimit()
- Returns
the limit cone
-
virtual void setLimitCone(const PxJointLimitCone &limit) = 0
Get the limit cone.
See also
PxJointLimitCone getLimit()
- Parameters
limit – [in] the limit cone
-
virtual void setSphericalJointFlags(PxSphericalJointFlags flags) = 0
Set the flags specific to the Spherical Joint.
Default PxSphericalJointFlags(0)

PxSphericalJointFlag setFlag() getFlags()
- Parameters
flags – [in] The joint flags.
-
virtual void setSphericalJointFlag(PxSphericalJointFlag::Enum flag, bool value) = 0
Set a single flag specific to a Spherical Joint to true or false.
See also
PxSphericalJointFlag, getFlags() setFlags()
- Parameters
flag – [in] The flag to set or clear.
value – [in] the value to which to set the flag
-
virtual PxSphericalJointFlags getSphericalJointFlags() const = 0
Get the flags specific to the Spherical Joint.
See also
PxSphericalJoint::flags, PxSphericalJointFlag setFlag() setFlags()
- Returns
the joint flags
-
virtual void setProjectionLinearTolerance(PxReal tolerance) = 0
Set the linear tolerance threshold for projection.
Projection is enabled if PxConstraintFlag::ePROJECTION is set for the joint.
If the joint separates by more than this distance along its locked degrees of freedom, the solver will move the bodies to close the distance.
Setting a very small tolerance may result in simulation jitter or other artifacts.
Sometimes it is not possible to project (for example when the joints form a cycle).
