PxSimulationStatistics

Defined in include/PxSimulationStatistics.h

class PxSimulationStatistics

Class used to retrieve statistics for a simulation step.

See also

PxScene::getSimulationStatistics()

Public Types

enum RbPairStatsType

Different types of rigid body collision pair statistics.

See also

getRbPairStats

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

PxPairFlag::eDETECT_CCD_CONTACT,

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.

See also

PxContactModifyCallback

enumerator eTRIGGER_PAIRS

Trigger shape pairs processed for the current simulation step.

See also

PxShapeFlag::eTRIGGER_SHAPE

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 nbStaticBodies

Number of static bodies for the current simulation step.

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 nbAggregates

Number of aggregates in the scene.

PxU32 nbArticulations
