Migrating From PhysX SDK 5.5 to 5.6#

  • This guide highlights all significant parts of the API that have changed in the last release. An application with a working integration of the older version of PhysX should be able to easily migrate to the newer version by following these pointers.

Development with GPU Accelerated Simulation#

  • With this release, we make the complete GPU source code available and no longer provide binaries for GPU acceleration. Users have to build the GPU binaries from source; in order to do so, please note the additional build instructions in the platform readmes.

Simulation#

  • PxFrictionType::eONE_DIRECTIONAL and ::eTWO_DIRECTIONAL were deprecated and have been removed. Please use PxFrictionType::ePATCH instead (or rather avoid setting the friction type altogether since PxFrictionType::ePATCH is the only supported type left).

Serialization#

Binary platform conversion has been removed and with it support for deterministic binary serialization. Determinism might be recovered for the regular binary serialization if the need arises in the future.

The following APIs have been removed without replacement:

  • PxBinaryConverter

  • PxConverterReportMode

  • PxGetPhysicsBinaryMetaData()

  • PxSerialization::serializeCollectionToBinaryDeterministic()

  • PxSerialization::dumpBinaryMetaData()

  • PxSerialization::createBinaryConverter()

  • PxBinaryMetaDataCallback

  • PxSerializationRegistry::registerBinaryMetaDataCallback()
