Detailed Description

Class to aggregate actors into a single broad-phase entry.

A PxAggregate object is a collection of PxActors, which will exist as a single entry in the broad-phase structures. This has 3 main benefits:

1) it reduces "broad phase pollution" by allowing a collection of spatially coherent broad-phase entries to be replaced by a single aggregated entry (e.g. a ragdoll or a single actor with a large number of attached shapes).

2) it reduces broad-phase memory usage

3) filtering can be optimized a lot if self-collisions within an aggregate are not needed. For example if you don't need collisions between ragdoll bones, it's faster to simply disable filtering once and for all, for the aggregate containing the ragdoll, rather than filtering out each bone-bone collision in the filter shader.

Member Function Documentation

◆ addActor()

virtual bool PxAggregate::addActor	(	PxActor &	actor,
		const PxBVHStructure *	bvhStructure = `NULL`
	)

pure virtual

Adds an actor to the aggregate object.

A warning is output if the total number of actors is reached, or if the incoming actor already belongs to an aggregate.

If the aggregate belongs to a scene, adding an actor to the aggregate also adds the actor to that scene.

If the actor already belongs to a scene, a warning is output and the call is ignored. You need to remove the actor from the scene first, before adding it to the aggregate.

Note: When BVHStructure is provided the actor shapes are grouped together. The scene query pruning structure inside PhysX SDK will store/update one bound per actor. The scene queries against such an actor will query actor bounds and then make a local space query against the provided BVH structure, which is in actor's local space.

Parameters

[in]	actor	The actor that should be added to the aggregate
[in]	bvhStructure	BVHStructure for actor shapes. return true if success

◆ addArticulation()

virtual bool PxAggregate::addArticulation ( PxArticulationBase & articulation )

pure virtual

Adds an articulation to the aggregate object.

A warning is output if the total number of actors is reached (every articulation link counts as an actor), or if the incoming articulation already belongs to an aggregate.

If the aggregate belongs to a scene, adding an articulation to the aggregate also adds the articulation to that scene.

If the articulation already belongs to a scene, a warning is output and the call is ignored. You need to remove the articulation from the scene first, before adding it to the aggregate.

Parameters

[in] articulation The articulation that should be added to the aggregate return true if success

◆ getActors()

virtual PxU32 PxAggregate::getActors	(	PxActor **	userBuffer,
		PxU32	bufferSize,
		PxU32	startIndex = `0`
	)		const

pure virtual

Retrieve all actors contained in the aggregate.

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

Parameters

[out]	userBuffer	The buffer to store the actor pointers.
[in]	bufferSize	Size of provided user buffer.
[in]	startIndex	Index of first actor pointer to be retrieved

Returns: Number of actor pointers written to the buffer.

See also: PxShape getNbShapes()

◆ getConcreteTypeName()

virtual const char* PxAggregate::getConcreteTypeName ( ) const

inlinevirtual

Returns string name of dynamic type.

Returns: Class name of most derived type of this object.

Implements PxBase.

◆ getMaxNbActors()

virtual PxU32 PxAggregate::getMaxNbActors ( ) const

pure virtual

Retrieves max amount of actors that can be contained in the aggregate.

Returns: Max aggregate size.

See also: PxPhysics::createAggregate()

◆ getNbActors()

virtual PxU32 PxAggregate::getNbActors ( ) const

pure virtual

Returns the number of actors contained in the aggregate.

You can use getActors() to retrieve the actor pointers.

Returns: Number of actors contained in the aggregate.

See also: PxActor getActors()

◆ getScene()

virtual PxScene* PxAggregate::getScene ( )

pure virtual

Retrieves the scene which this aggregate belongs to.

Returns: Owner Scene. NULL if not part of a scene.

See also: PxScene

◆ getSelfCollision()

virtual bool PxAggregate::getSelfCollision ( ) const

pure virtual

Retrieves aggregate's self-collision flag.

Returns: self-collision flag

◆ isKindOf()

virtual bool PxAggregate::isKindOf ( const char * superClass ) const

inlineprotectedvirtual

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

Reimplemented from PxBase.

References PxBase::isKindOf().

◆ release()

virtual void PxAggregate::release ( )

pure virtual

Deletes the aggregate object.

Deleting the PxAggregate object does not delete the aggregated actors. If the PxAggregate object belongs to a scene, the aggregated actors are automatically re-inserted in that scene. If you intend to delete both the PxAggregate and its actors, it is best to release the actors first, then release the PxAggregate when it is empty.

Implements PxBase.

◆ removeActor()

virtual bool PxAggregate::removeActor ( PxActor & actor )

pure virtual

Removes an actor from the aggregate object.

A warning is output if the incoming actor does not belong to the aggregate. Otherwise the actor is removed from the aggregate. If the aggregate belongs to a scene, the actor is reinserted in that scene. If you intend to delete the actor, it is best to call PxActor::release() directly. That way the actor will be automatically removed from its aggregate (if any) and not reinserted in a scene.

Parameters

[in] actor The actor that should be removed from the aggregate return true if success

◆ removeArticulation()

virtual bool PxAggregate::removeArticulation ( PxArticulationBase & articulation )

pure virtual

Removes an articulation from the aggregate object.

A warning is output if the incoming articulation does not belong to the aggregate. Otherwise the articulation is removed from the aggregate. If the aggregate belongs to a scene, the articulation is reinserted in that scene. If you intend to delete the articulation, it is best to call PxArticulation::release() directly. That way the articulation will be automatically removed from its aggregate (if any) and not reinserted in a scene.

Parameters

[in] articulation The articulation that should be removed from the aggregate return true if success
