PxPruningStructure

Defined in include/PxPruningStructure.h

class PxPruningStructure : public PxBase

A precomputed pruning structure to accelerate scene queries against newly added actors.

The pruning structure can be provided to PxScene:: addActors() in which case it will get merged directly into the scene query optimization AABB tree, thus leading to improved performance when doing queries against the newly added actors. This applies to both static and dynamic actors.

See also

PxScene::addActors PxCollection

Note

PxPruningStructure objects can be added to a collection and get serialized.

Note

Adding a PxPruningStructure object to a collection will also add the actors that were used to build the pruning structure.

Note

PxPruningStructure must be released before its rigid actors.

Note

PxRigidBody objects can be in one PxPruningStructure only.

Note

Changing the bounds of PxRigidBody objects assigned to a pruning structure that has not been added to a scene yet will invalidate the pruning structure. Same happens if shape scene query flags change or shape gets removed from an actor.

Public Functions

virtual void release() = 0

Release this object.

virtual PxU32 getRigidActors(PxRigidActor **userBuffer, PxU32 bufferSize, PxU32 startIndex = 0) const = 0

Retrieve rigid actors in the pruning structure.

You can retrieve the number of rigid actor pointers by calling getNbRigidActors()

See also

PxRigidActor

Parameters
  • userBuffer[out] The buffer to store the actor pointers.

  • bufferSize[in] Size of provided user buffer.

  • startIndex[in] Index of first actor pointer to be retrieved

Returns

Number of rigid actor pointers written to the buffer.

virtual PxU32 getNbRigidActors() const = 0

Returns the number of rigid actors in the pruning structure.

You can use getRigidActors() to retrieve the rigid actor pointers.

PxRigidActor

Returns

Number of rigid actors in the pruning structure.

virtual const void *getStaticMergeData() const = 0

Gets the merge data for static actors.

This is mainly called by the PxSceneQuerySystem::merge() function to merge a PxPruningStructure with the internal data-structures of the scene-query system.

See also

PxSceneQuerySystem::merge()

Returns

Implementation-dependent merge data for static actors.

virtual const void *getDynamicMergeData() const = 0

Gets the merge data for dynamic actors.

This is mainly called by the PxSceneQuerySystem::merge() function to merge a PxPruningStructure with the internal data-structures of the scene-query system.

See also

PxSceneQuerySystem::merge()

Returns

Implementation-dependent merge data for dynamic actors.

inline virtual const char *getConcreteTypeName() const

Returns string name of dynamic type.

Returns

Class name of most derived type of this object.

template<class T>
inline T *is()
template<class T>
inline const T *is() const
inline PxType getConcreteType() const

Returns concrete type of object.

PxConcreteType

Returns

PxConcreteType::Enum of serialized object

inline void setBaseFlag(PxBaseFlag::Enum flag, bool value)

Set PxBaseFlag

Parameters
  • flag[in] The flag to be set

  • value[in] The flags new value

inline void setBaseFlags(PxBaseFlags inFlags)

Set PxBaseFlags

PxBaseFlags

Parameters

inFlags[in] The flags to be set

inline PxBaseFlags getBaseFlags() const

Returns PxBaseFlags.

Returns

PxBaseFlags

inline virtual bool isReleasable() const

Whether the object is subordinate.

A class is subordinate, if it can only be instantiated in the context of another class.

PxSerialization::isSerializable

Returns

Whether the class is subordinate

inline virtual ~PxPruningStructure()
inline virtual bool isKindOf(const char *name) const

Returns whether a given type name matches with the type of this instance.
