Adds to a collection all objects such that it can be successfully serialized.

A collection C is complete relative to an other collection D if every object required by C is either in C or D. This function adds objects to a collection, such that it becomes complete with respect to the exceptFor collection. Completeness is needed for serialization. See PxSerialization::serializeCollectionToBinary, PxSerialization::serializeCollectionToXml.

Sdk objects require other sdk object according to the following rules:

• joints require their actors and constraint
• rigid actors require their shapes
• shapes require their material(s) and mesh (triangle mesh, convex mesh or height field), if any
• articulations require their links and joints
• aggregates require their actors
• cloth actors require their cloth fabric

If followJoints is specified another rule is added:

• actors require their joints

Specifying followJoints will make whole jointed actor chains being added to the collection. Following chains is interrupted whenever a object in exceptFor is encountered.

Parameters:

[in,out]	collection	Collection which is completed
[in]	sr	PxSerializationRegistry instance with information about registered classes.
[in]	exceptFor	Optional exemption collection
[in]	followJoints	Specifies whether joints should be added for jointed actors

Creates binary converter for re-targeting binary-serialized data.

Returns:

Binary converter instance.

Deserializes a PxCollection from memory.

Creates a collection from memory. If the collection has external dependencies another collection can be provided to resolve these.

The memory block provided has to be 128 bytes aligned and contain a contiguous serialized collection as written by PxSerialization::serializeCollectionToBinary. The contained binary data needs to be compatible with the current binary format version which is defined by "PX_PHYSICS_VERSION_MAJOR.PX_PHYSICS_VERSION_MINOR.PX_PHYSICS_VERSION_BUGFIX-PX_BINARY_SERIAL_VERSION". For a list of compatible sdk releases refer to the documentation of PX_BINARY_SERIAL_VERSION.

Parameters:

[in]	memBlock	Pointer to memory block containing the serialized collection
[in]	sr	PxSerializationRegistry instance with information about registered classes.
[in]	externalRefs	Collection to resolve external dependencies

Creates a PxCollection from XML data.

Parameters:

	inputData	The input data containing the XML collection.
	cooking	PxCooking instance used for sdk object instantiation.
	sr	PxSerializationRegistry instance with information about registered classes.
	externalRefs	PxCollection used to resolve external references.
	stringTable	PxStringTable instance used for storing object names.
	outArgs	Optional parameters of physics and scene deserialized from XML. See PxSerialization::PxXmlMiscParameter

Returns:

a pointer to a PxCollection if successful or NULL if it failed.

PxCollection, PxSerializationRegistry, PxInputData, PxStringTable, PxCooking, PxSerialization::PxXmlMiscParameter

Creates an application managed registry for serialization.

Parameters:

[in]

physics

Physics SDK to generate create serialization registry

Returns:

PxSerializationRegistry instance.

PxSerializationRegistry

Creates PxSerialObjectId values for unnamed objects in a collection.

Creates PxSerialObjectId names for unnamed objects in a collection starting at a base value and incrementing, skipping values that are already assigned to objects in the collection.

Parameters:

[in,out]	collection	Collection for which names are created
[in]	base	Start address for PxSerialObjectId names

PxCollection

Dumps the binary meta-data to a stream.

A meta-data file contains information about the SDK's internal classes and about custom user types ready for serialization. Such a file is needed to convert binary-serialized data from one platform to another (re-targeting). The converter needs meta-data files for the source and target platforms to perform conversions.

Custom user types can be supported with PxSerializationRegistry::registerBinaryMetaDataCallback (see the guide for more information).

Parameters:

[out]	outputStream	Stream to write meta data to
[in]	sr	PxSerializationRegistry instance with information about registered classes used for conversion.

PxOutputStream, PxSerializationRegistry

Returns whether the collection is serializable with the externalReferences collection.

Some definitions to explain whether a collection can be serialized or not:

For definitions of requires and complete see PxSerialization::complete

A serializable object is subordinate if it cannot be serialized on it's own The following objects are subordinate:

• articulation links
• articulation joints
• joints

A collection C can be serialized with external references collection D iff

• C is complete relative to D (no dangling references)
• Every object in D required by an object in C has a valid ID (no unnamed references)
• Every subordinate object in C is required by another object in C (no orphans)

Parameters:

[in]	collection	Collection to be checked
[in]	sr	PxSerializationRegistry instance with information about registered classes.
[in]	externalReferences	the external References collection

Returns:

Whether the collection is serializable

PxSerialization::complete, PxSerialization::serializeCollectionToBinary, PxSerialization::serializeCollectionToXml, PxSerializationRegistry

Serializes a collection to a binary stream.

Serializes a collection to a stream. In order to resolve external dependencies the externalReferences collection has to be provided. Optionally names of objects that where set for example with PxActor::setName are serialized along with the objects.

The collection can be successfully serialized if isSerializable(collection) returns true. See isSerializable.

The implementation of the output stream needs to fulfill the requirements on the memory block input taken by PxSerialization::createCollectionFromBinary.

Note:

Serialization of objects in a scene that is simultaneously being simulated is not supported and leads to undefined behavior.

Parameters:

[out]	outputStream	into which the collection is serialized
[in]	collection	Collection to be serialized
[in]	sr	PxSerializationRegistry instance with information about registered classes.
[in]	externalRefs	Collection used to resolve external dependencies
[in]	exportNames	Specifies whether object names are serialized

Returns:

Whether serialization was successful

Serializes a physics collection to an XML output stream.

The collection to be serialized needs to be complete

See also:

PxSerialization.complete. Optionally the XML may contain meshes in binary cooked format for fast loading. It does this when providing a valid non-null PxCooking pointer.

Note:

Serialization of objects in a scene that is simultaneously being simulated is not supported and leads to undefined behavior.

Parameters:

	outputStream	Stream to save collection to.
	collection	PxCollection instance which is serialized. The collection needs to be complete with respect to the externalRefs collection.
	sr	PxSerializationRegistry instance with information about registered classes.
	cooking	Optional pointer to cooking instance. If provided, cooked mesh data is cached for fast loading.
	externalRefs	Collection containing external references.
	inArgs	Optional parameters of physics and scene serialized to XML along with the collection. See PxSerialization::PxXmlMiscParameter

Returns:

true if the collection is successfully serialized.
