Public Members

PxU8 *frictionPtr#: InOut: Friction patch correlation data. Set each frame by solver. Can be retained for improved behavior or discarded each frame.

const PxContactPoint *contacts#: The start of the contacts for this pair.

PxU32 numContacts#: The total number of contacts this pair references.

PxU8 frictionCount#: The total number of friction patches in this pair.

bool hasMaxImpulse#: Defines whether this pairs has maxImpulses clamping enabled.

bool disableStrongFriction#: Defines whether this pair disables strong friction (sticky friction correlation)

bool hasForceThresholds#: Defines whether this pair requires force thresholds.

PxReal restDistance#: A distance at which the solver should aim to hold the bodies separated. Default is 0.

PxReal maxCCDSeparation#: A distance used to configure speculative CCD behavior. Default is PX_MAX_F32. Set internally in PhysX for bodies with eENABLE_SPECULATIVE_CCD on. Do not set directly!

PxReal *contactForces#: Out: A buffer for the solver to write applied contact forces to.

PxU32 startFrictionPatchIndex#: Start index of friction patch in the correlation buffer. Set by friction correlation.

PxU32 numFrictionPatches#: Total number of friction patches in this pair. Set by friction correlation.

PxU32 startContactPatchIndex#: The start index of this pair’s contact patches in the correlation buffer. For internal use only.

PxU16 numContactPatches#: Total number of contact patches.

PxU16 axisConstraintCount#: Axis constraint count. Defines how many constraint rows this pair has produced. Useful for statistical purposes.

PxReal maxImpulse#: The maximum impulse the solver is allowed to introduce for this pair of bodies.

PxReal torsionalPatchRadius#: This defines the radius of the contact patch used to apply torsional friction.

PxReal minTorsionalPatchRadius#: This defines the minimum radius of the contact patch used to apply torsional friction.

PxReal offsetSlop#: Slop value used to snap contact line of action back in-line with the COM.

PxConstraintInvMassScale invMassScales#: In: The local mass scaling for this pair.

PxSolverConstraintDesc *desc#: Output: The PxSolverConstraintDesc filled in by contact prep.

const PxTGSSolverBodyVel *body0#: In: The first body. Stores velocity information. Unused unless contact involves articulations.

const PxTGSSolverBodyVel *body1#: In: The second body. Stores velocity information. Unused unless contact involves articulations.

const PxTGSSolverBodyTxInertia *body0TxI#: In: The first PxTGSSolverBodyTxInertia. Stores the delta body to world transform and sqrtInvInertia for first body.

const PxTGSSolverBodyTxInertia *body1TxI#: In: The second PxTGSSolverBodyTxInertia. Stores the delta body to world transform and sqrtInvInertia for second body.

const PxTGSSolverBodyData *bodyData0#: In: The first PxTGSSolverBodyData. Stores mass and miscellaneous information for the first body.

const PxTGSSolverBodyData *bodyData1#: In: The second PxTGSSolverBodyData. Stores mass and miscellaneous information for the second body.

PxTransform bodyFrame0#: In: The world-space transform of the first body.

PxTransform bodyFrame1#: In: The world-space transform of the second body.

PxSolverContactDesc::BodyState bodyState0#: In: Defines what kind of actor the first body is.

PxSolverContactDesc::BodyState bodyState1#: In: Defines what kind of actor the second body is.

void *writeback#: Pointer to constraint writeback structure. Reports back joint breaking. If not required, set to NULL.

void *shapeInteraction#: Pointer to shape interaction. Used for force threshold reports in solver. Set to NULL if using immediate mode.
