Detailed Description

Applied to a Physics Joint that must be part of an articulation.

Supported joint types are: PhysicsRevoluteJoint (with a limit set), PhysicsPrismaticJoint as well as the more generic PhysicsJoint if all linear degrees of freedom are locked.

This schema allows to interconnect the degrees of freedom of two joints according to the relationship: jointPosition + (gearing * referenceJointPosition) + offset = 0. This can be used to have, for example, one joint mimic the motion of another joint. The term "position" does not necessarily mean a translational unit, in the case of an angular degree of freedom it is an angle. The mimic joint operates on a single degree of freedom which is specified through the instance name of this multiple apply schema. The allowed instance name tokens are "rotX", "rotY" and "rotZ". See the documentation of the attribute referenceJointAxis for more info related to specifying the degree of freedom to operate on. Notes: 1) the two joints have to be part of the same articulation. 2) once the simulation has started, a significant performance penalty will be incurred if a mimic joint is added or removed, if the referenceJoint relationship is changed or if the referenceJointAxis attributes is modified. 3) the mimic joint relationship is interpreted as a two-way interaction and an impulse will get applied to the reference joint as well.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in PhysxSchemaTokens. So to set an attribute to the value "rightHanded", use PhysxSchemaTokens->rightHanded as the value.

PhysxSchemaPhysxMimicJointAPI	(	const UsdPrim &	prim = `UsdPrim()`,
		const TfToken &	name = `TfToken()`
	)

inlineexplicit

Construct a PhysxSchemaPhysxMimicJointAPI on UsdPrim prim with name name .

Equivalent to PhysxSchemaPhysxMimicJointAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( "physxMimicJoint:name"));

for a valid prim, but will not immediately throw an error for an invalid prim

		const TfToken &	name
	)

inlineexplicit

Construct a PhysxSchemaPhysxMimicJointAPI on the prim held by schemaObj with name name.

Should be preferred over PhysxSchemaPhysxMimicJointAPI(schemaObj.GetPrim(), name), as it preserves SchemaBase state.

Member Function Documentation

PHYSXSCHEMA_API UsdSchemaKind _GetSchemaKind ( ) const

overrideprotected

Returns the kind of schema this class belongs to.

See Also: UsdSchemaKind

static PHYSXSCHEMA_API PhysxSchemaPhysxMimicJointAPI Apply	(	const UsdPrim &	prim,
		const TfToken &	name
	)

static

Applies this multiple-apply API schema to the given prim along with the given instance name, name.

This information is stored by adding "PhysxMimicJointAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is 'instance1', the token 'PhysxMimicJointAPI:instance1' is added to 'apiSchemas'.

Returns: A valid PhysxSchemaPhysxMimicJointAPI object is returned upon success. An invalid (or empty) PhysxSchemaPhysxMimicJointAPI object is returned upon failure. See UsdPrim::ApplyAPI() for conditions resulting in failure.

static PHYSXSCHEMA_API bool CanApply	(	const UsdPrim &	prim,
		const TfToken &	name,
		std::string *	whyNot = `nullptr`
	)

static

Returns true if this multiple-apply API schema can be applied, with the given instance name, name, to the given prim.

If this schema can not be a applied the prim, this returns false and, if provided, populates whyNot with the reason it can not be applied.

Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.

See GetGearingAttr(), and also Usd_Create_Or_Get_Property 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.

static PHYSXSCHEMA_API PhysxSchemaPhysxMimicJointAPI Get	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Return a PhysxSchemaPhysxMimicJointAPI holding the prim adhering to this schema at path on stage.

If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. path must be of the format <path>.physxMimicJoint:name .

This is shorthand for the following:

*  TfToken name = SdfPath::StripNamespace(path.GetToken());
*  PhysxSchemaPhysxMimicJointAPI(
*      stage->GetPrimAtPath(path.GetPrimPath()), name);
*  

static PHYSXSCHEMA_API PhysxSchemaPhysxMimicJointAPI Get	(	const UsdPrim &	prim,
		const TfToken &	name
	)

static

Return a PhysxSchemaPhysxMimicJointAPI with name name holding the prim prim.

Shorthand for PhysxSchemaPhysxMimicJointAPI(prim, name);

static PHYSXSCHEMA_API std::vector<PhysxSchemaPhysxMimicJointAPI> GetAll ( const UsdPrim & prim )

static

Return a vector of all named instances of PhysxSchemaPhysxMimicJointAPI on the given prim.

PHYSXSCHEMA_API UsdAttribute GetGearingAttr ( ) const

Declaration	`float offset = 0`
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetReferenceJointAxisAttr ( ) const

The axis that marks the degree of freedom of the reference joint to mimic.

Has to be a valid degree of freedom on the reference joint. For joint types with a single degree of freedom (like PhysicsRevoluteJoint or PhysicsPrismaticJoint), this attribute will be ignored since the axis is defined implicitly. The mimic joint connects <targetJoint, targetJointAxis> to <referenceJoint, referenceJointAxis> with targetJoint being the prim that has PhysxMimicJointAPI applied and targetJointAxis being defined through the instance name token of PhysxMimicJointAPI.
