Public Functions

inline explicit PhysxSchemaPhysxPhysicsJointInstancer( const UsdPrim &prim = UsdPrim(), )#: Construct a PhysxSchemaPhysxPhysicsJointInstancer on UsdPrim prim. Equivalent to PhysxSchemaPhysxPhysicsJointInstancer::Get(prim.GetStage(), prim.GetPath()) for a valid prim , but will not immediately throw an error for an invalid prim.

inline explicit PhysxSchemaPhysxPhysicsJointInstancer( const UsdSchemaBase &schemaObj, )#: Construct a PhysxSchemaPhysxPhysicsJointInstancer on the prim held by schemaObj . Should be preferred over PhysxSchemaPhysxPhysicsJointInstancer(schemaObj.GetPrim()), as it preserves SchemaBase state.

inline virtual ~PhysxSchemaPhysxPhysicsJointInstancer()#: Destructor.

inline UsdRelationship GetPhysicsBody0sRel() const#: Required property. The rel must contain either exactly one UsdGeomPointInstancer that instances rigid bodies; or one or more rigid-body prims in the stage. If the rel is to a point instancer, the body0Indices must be specified.

inline UsdRelationship CreatePhysicsBody0sRel() const#: See GetPhysicsBody0sRel(), and also Create vs Get Property Methods for when to use Get vs Create.

inline UsdAttribute GetPhysicsProtoIndicesAttr() const#

Required property. Per-instance index into prototypes relationship that identifies what physics prims are instanced. Topology attribute - can be animated, but at a potential performance impact for streaming.


Declaration	`int[] physics:protoIndices`
C++ Type	VtArray<int>
Usd Type	SdfValueTypeNames->IntArray

inline UsdAttribute CreatePhysicsProtoIndicesAttr() const#: See GetPhysicsProtoIndicesAttr(), and also Create vs Get Property Methods for when to use Get vs Create.

inline UsdRelationship GetPhysicsPrototypesRel() const#: Required property. Orders and targets the prototype root prims, which can be located anywhere in the scenegraph that is convenient, although we promote organizing prototypes as children of the PhysxPhysicsInstancer. The position of a prototype in this relationship defines the value an instance would specify in the protoIndices attribute to instance that prototype. Since relationships are uniform, this property cannot be animated.

inline UsdRelationship CreatePhysicsPrototypesRel() const#: See GetPhysicsPrototypesRel(), and also Create vs Get Property Methods for when to use Get vs Create.

inline UsdAttribute GetVisibilityAttr() const#

Visibility is meant to be the simplest form of “pruning” visibility that is supported by most DCC apps. Visibility is animatable, allowing a sub-tree of geometry to be present for some segment of a shot, and absent from others; unlike the action of deactivating geometry prims, invisible geometry is still available for inspection, for positioning, for defining volumes, etc.


Declaration	`token visibility = "inherited"`
C++ Type	TfToken
Usd Type	SdfValueTypeNames->Token
Allowed Values	inherited, invisible

inline UsdAttribute CreateVisibilityAttr() const#: See GetVisibilityAttr(), and also Create vs Get Property Methods for when to use Get vs Create. If specified, author defaultValue as the attribute’s default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

inline UsdAttribute GetPurposeAttr() const#

Purpose is a classification of geometry into categories that can each be independently included or excluded from traversals of prims on a stage, such as rendering or bounding-box computation traversals.

See UsdGeom_ImageablePurpose for more detail about how purpose is computed and used.


Declaration	`uniform token purpose = "default"`
C++ Type	TfToken
Usd Type	SdfValueTypeNames->Token
Variability	SdfVariabilityUniform
Allowed Values	default, render, proxy, guide

inline UsdAttribute CreatePurposeAttr() const#: See GetPurposeAttr(), and also Create vs Get Property Methods for when to use Get vs Create. If specified, author defaultValue as the attribute’s default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

inline UsdRelationship GetProxyPrimRel() const#

The proxyPrim relationship allows us to link a prim whose purpose is “render” to its (single target) purpose=”proxy” prim. This is entirely optional, but can be useful in several scenarios:

In a pipeline that does pruning (for complexity management) by deactivating prims composed from asset references, when we deactivate a purpose=”render” prim, we will be able to discover and additionally deactivate its associated purpose=”proxy” prim, so that preview renders reflect the pruning accurately.

DCC importers may be able to make more aggressive optimizations for interactive processing and display if they can discover the proxy for a given render prim.

With a little more work, a Hydra-based application will be able to map a picked proxy prim back to its render geometry for selection.

Note

It is only valid to author the proxyPrim relationship on prims whose purpose is “render”.

inline UsdRelationship CreateProxyPrimRel() const#: See GetProxyPrimRel(), and also Create vs Get Property Methods for when to use Get vs Create.

UsdPrim GetPrim() const#: Return this schema object’s held prim.

SdfPath GetPath() const#: Return the SdfPath to this schema object’s held prim.

inline explicit operator bool() const#

Check if this schema object is compatible with it’s held prim and that the prim is valid.

A typed schema object is compatible if the held prim’s type is or is a subtype of the schema’s type. Based on prim.IsA().

An API schema object is compatible if the API is of type SingleApplyAPI or UsdSchemaType::MultipleApplyAPI, and the schema has been applied to the prim. Based on prim.HasAPI.

This method invokes polymorphic behaviour.
