Member Function Documentation

static PxCollection* PxCollectionExt::createCollection ( PxScene scene  )  [static]

Collects all objects from a PxScene.

This function creates a new collection from all objects that where added to the specified PxScene. Instances of the following types are included: PxActor, PxAggregate, PxArticulation and PxJoint (other PxConstraint types are not included).

This is a helper function to ease the creation of collections for serialization. The function PxSerialization.complete() can be used to complete the collection with required objects prior to serialization.

Parameters:
[in] scene The PxScene instance from which objects are collected. See PxScene
Returns:
Collection to which objects are added. See PxCollection
See also:
PxCollection, PxScene, PxSerialization.complete()

static PxCollection* PxCollectionExt::createCollection ( PxPhysics physics  )  [static]

Collects all objects in PxPhysics that are shareable across multiple scenes.

This function creates a new collection from all objects that are shareable across multiple scenes. Instances of the following types are included: PxConvexMesh, PxTriangleMesh, PxHeightField, PxShape, PxMaterial and PxClothFabric.

This is a helper function to ease the creation of collections for serialization.

Parameters:
[in] physics The physics SDK instance from which objects are collected. See PxPhysics
Returns:
Collection to which objects are added. See PxCollection
See also:
PxCollection, PxPhysics

static void PxCollectionExt::releaseObjects ( PxCollection collection,
bool  releaseExclusiveShapes = true 
) [static]

Removes and releases all object from a collection.

The Collection itself is not released.

If the releaseExclusiveShapes flag is not set to true, release() will not be called on exclusive shapes.

It is assumed that the application holds a reference to each of the objects in the collection, with the exception of objects that are not releasable (PxBase::isReleasable()). In general, objects that violate this assumption need to be removed from the collection prior to calling releaseObjects.

Note:
when a shape is created with PxRigidActor::createShape() or PxRigidActorExt::createExclusiveShape(), the only counted reference is held by the actor. If such a shape and its actor are present in the collection, the reference count will be decremented once when the actor is released, and once when the shape is released, resulting in undefined behavior. Shape reference counts can be incremented with PxShape::acquireReference().
Parameters:
[in] collection to remove and release all object from.
[in] releaseExclusiveShapes if this parameter is set to false, release() will not be called on exclusive shapes.

static void PxCollectionExt::remove ( PxCollection collection,
PxType  concreteType,
PxCollection to = NULL 
) [static]

Removes objects of a given type from a collection, potentially adding them to another collection.

Parameters:
[in,out] collection Collection from which objects are removed
[in] concreteType PxConcreteType of sdk objects that should be removed
[in,out] to Optional collection to which the removed objects are added
