class PxSimulationStatistics
Class used to retrieve statistics for a simulation step.

Public Types
-
enum RbPairStatsType
Different types of rigid body collision pair statistics.
See also
Values:
-
enumerator eDISCRETE_CONTACT_PAIRS
Shape pairs processed as discrete contact pairs for the current simulation step.
-
enumerator eCCD_PAIRS
Shape pairs processed as swept integration pairs for the current simulation step.
See also
Note
Counts the pairs for which special CCD (continuous collision detection) work was actually done and NOT the number of pairs which were configured for CCD. Furthermore, there can be multiple CCD passes and all processed pairs of all passes are summed up, hence the number can be larger than the amount of pairs which have been configured for CCD.
-
enumerator eMODIFIED_CONTACT_PAIRS
Shape pairs processed with user contact modification enabled for the current simulation step.

-
enumerator eTRIGGER_PAIRS
Trigger shape pairs processed for the current simulation step.

-
enumerator eDISCRETE_CONTACT_PAIRS
Public Functions
-
inline PxU32 getNbBroadPhaseAdds() const
Get number of broadphase volumes added for the current simulation step.
- Returns
Number of broadphase volumes added.
-
inline PxU32 getNbBroadPhaseRemoves() const
Get number of broadphase volumes removed for the current simulation step.
- Returns
Number of broadphase volumes removed.
-
inline PxU32 getRbPairStats(RbPairStatsType pairType, PxGeometryType::Enum g0, PxGeometryType::Enum g1) const
Get number of shape collision pairs of a certain type processed for the current simulation step.
There is an entry for each geometry pair type.
Note
entry[i][j] = entry[j][i], hence, if you want the sum of all pair types, you need to discard the symmetric entries
- Parameters
pairType – [in] The type of pair for which to get information
g0 – [in] The geometry type of one pair object
g1 – [in] The geometry type of the other pair object
- Returns
Number of processed pairs of the specified geometry types.

Public Members
-
PxU32 nbActiveConstraints
Number of active PxConstraint objects (joints etc.) for the current simulation step.
-
PxU32 nbActiveDynamicBodies
Number of active dynamic bodies for the current simulation step.
Note
Does not include active kinematic bodies
-
PxU32 nbActiveKinematicBodies
Number of active kinematic bodies for the current simulation step.
Note
Kinematic deactivation occurs at the end of the frame after the last call to PxRigidDynamic::setKinematicTarget() was called so kinematics that are deactivated in a given frame will be included by this counter.
-
PxU32 nbDynamicBodies
Number of dynamic bodies for the current simulation step.
Note
Includes inactive bodies and articulation links
Note
Does not include kinematic bodies
-
PxU32 nbKinematicBodies
Number of kinematic bodies for the current simulation step.
Note
Includes inactive bodies
-
PxU32 nbShapes[PxGeometryType::eGEOMETRY_COUNT]
Number of shapes of each geometry type.
-
PxU32 nbAxisSolverConstraints
The number of 1D axis constraints(joints+contact) present in the current simulation step.
-
PxU32 compressedContactSize
The size (in bytes) of the compressed contact stream in the current simulation step.
-
PxU32 requiredContactConstraintMemory
The total required size (in bytes) of the contact constraints in the current simulation step.
-
PxU32 peakConstraintMemory
The peak amount of memory (in bytes) that was allocated for constraints (this includes joints) in the current simulation step.
-
PxU32 nbDiscreteContactPairsWithCacheHits
Total number of (non CCD) pairs for which contacts are successfully cached (<=nbDiscreteContactPairsTotal)
Note
This includes pairs for which no contacts are generated, it still counts as a cache hit.
-
PxU32 nbDiscreteContactPairsWithContacts
Total number of (non CCD) pairs for which at least 1 contact was generated (<=nbDiscreteContactPairsTotal)
