Typedef Documentation

using UsdPhysicsReportFn = std::function<void(UsdPhysicsObjectType type, TfSpan<const SdfPath> primPaths, TfSpan<const UsdPhysicsObjectDesc> objectDescs, const VtValue& userData)>

UsdPhysicsReportFn - report function that reports parsed data in a batched manner. This function is called after all the parsing is done and all the physics descriptors are constructed.

Parameters

[in]	type	Type of the parsed physics objects
[in]	primPaths	Span of prim paths of the reported type
[in]	objectDescs	Corresponding span of object descriptors of the reported type
[in]	userData	User data provided to the called parsing function

Function Documentation

USDPHYSICS_API bool LoadUsdPhysicsFromRange	(	const UsdStageWeakPtr	stage,
		const std::vector< SdfPath > &	includePaths,
		UsdPhysicsReportFn	reportFn,
		const VtValue &	userData,
		const std::vector< SdfPath > *	excludePaths = nullptr,
		const CustomUsdPhysicsTokens *	customPhysicsTokens = nullptr,
		const std::vector< SdfPath > *	simulationOwners = nullptr
	)

Load USD physics from a given list of paths. This helper function traverses the provided USD stage by constructing UsdPrimRanges from given include paths (subhierarchies can be prunes through exclude paths) and returns parsed physics objects through the report function.

See the parsing utils documentation for more details.

Parameters

[in]	stage	Stage to be traversed and parsed.
[in]	includePaths	The vector of SdfPaths that are used to construct UsdPrimRange for traversals. For each path a UsdPrim is found on the stage and UsdRange traversal is constructed from it. All the traversed UsdPrims are parsed and physics descriptors are constructed and reported through the report function.
[in]	reportFn	Report function that gets parsed USD physics data see

UsdPhysicsReportFn

Parameters

[in]	userData	User data passed to report function, this can be arbitrary data structure, user data acts as a bridge between reportFn and the data structures understood by the Simulator. Implementer of reportFn can use the parsed "objectDesc" to populate these simulator-compatible data structures, which are passed as userData here.
[in]	excludePaths	The vector of SdfPaths that are used to prune UsdPrims from the parsing UsdPrimRange traversals constructed from the include paths.
[in]	customPhysicsTokens	Custom tokens to be reported by the parsing see

Parameters

[in]

simulationOwners

List of simulation owners that should be parsed, adding SdfPath() indicates that objects without a simulation owner should be parsed too.

Returns

True if load was successful
