Detailed Description

Applies physics body attributes to any UsdGeomXformable prim and marks that prim to be driven by a simulation. If a simulation is running it will update this prim's pose. All prims in the hierarchy below this prim should move accordingly.

typedef MassInformation UsdPhysicsRigidBodyAPI::MassInformationFnSig(const UsdPrim &)

Mass information function signature, for given UsdPrim gather MassInformation.

Constructor & Destructor Documentation

UsdPhysicsRigidBodyAPI::UsdPhysicsRigidBodyAPI ( const UsdPrim prim = UsdPrim())
inlineexplicit

Construct a UsdPhysicsRigidBodyAPI on UsdPrim prim . Equivalent to UsdPhysicsRigidBodyAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 75 of file rigidBodyAPI.h.

UsdPhysicsRigidBodyAPI::UsdPhysicsRigidBodyAPI ( const UsdSchemaBase schemaObj)
inlineexplicit

Construct a UsdPhysicsRigidBodyAPI on the prim held by schemaObj . Should be preferred over UsdPhysicsRigidBodyAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 83 of file rigidBodyAPI.h.

virtual USDPHYSICS_API UsdPhysicsRigidBodyAPI::~UsdPhysicsRigidBodyAPI ( )

Destructor.

Member Function Documentation

USDPHYSICS_API UsdSchemaKind UsdPhysicsRigidBodyAPI::_GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind

Reimplemented from UsdAPISchemaBase.

static USDPHYSICS_API UsdPhysicsRigidBodyAPI UsdPhysicsRigidBodyAPI::Apply ( const UsdPrim prim)
static

Applies this single-apply API schema to the given prim. This information is stored by adding "PhysicsRigidBodyAPI" to the token-valued, listOp metadata apiSchemas on the prim.

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

UsdPrim::RemoveAPI()
static USDPHYSICS_API bool UsdPhysicsRigidBodyAPI::CanApply ( const UsdPrim prim,
std::string whyNot = nullptr 
)
static

Returns true if this single-apply API schema can be applied to the given prim. If this schema can not be a applied to 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.

USDPHYSICS_API float UsdPhysicsRigidBodyAPI::ComputeMassProperties ( GfVec3f diagonalInertia,

) const

Compute mass properties of the rigid body diagonalInertia Computed diagonal of the inertial tensor for the rigid body. com Computed center of mass for the rigid body. principalAxes Inertia tensor's principal axes orienttion for the rigid body. massInfoFn Callback function to get collision mass information.

Returns
Computed mass of the rigid body
USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::CreateAngularVelocityAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetAngularVelocityAttr(), 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.

USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::CreateKinematicEnabledAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetKinematicEnabledAttr(), 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.

USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::CreateRigidBodyEnabledAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetRigidBodyEnabledAttr(), 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.

USDPHYSICS_API UsdRelationship UsdPhysicsRigidBodyAPI::CreateSimulationOwnerRel ( ) const

See GetSimulationOwnerRel(), and also Usd_Create_Or_Get_Property for when to use Get vs Create

USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::CreateStartsAsleepAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetStartsAsleepAttr(), 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.

bool  writeSparsely = false 
) const

See GetVelocityAttr(), 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 USDPHYSICS_API UsdPhysicsRigidBodyAPI UsdPhysicsRigidBodyAPI::Get ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Return a UsdPhysicsRigidBodyAPI 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. This is shorthand for the following:

UsdPhysicsRigidBodyAPI(stage->GetPrimAtPath(path));
USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::GetAngularVelocityAttr ( ) const

Angular velocity in the same space as the node's xform. Units: degrees/second.

C++ Type GfVec3f
Usd Type SdfValueTypeNames->Vector3f
USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::GetKinematicEnabledAttr ( ) const

Determines whether the body is kinematic or not. A kinematic body is a body that is moved through animated poses or through user defined poses. The simulation derives velocities for the kinematic body based on the external motion. When a continuous motion is not desired, this kinematic flag should be set to false.

Declaration bool physics:kinematicEnabled = 0
C++ Type bool
Usd Type SdfValueTypeNames->Bool
USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::GetRigidBodyEnabledAttr ( ) const

Determines if this PhysicsRigidBodyAPI is enabled.

Declaration bool physics:rigidBodyEnabled = 1
C++ Type bool
Usd Type SdfValueTypeNames->Bool
static USDPHYSICS_API const TfTokenVector& UsdPhysicsRigidBodyAPI::GetSchemaAttributeNames ( bool  includeInherited = true)
static

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.

USDPHYSICS_API UsdRelationship UsdPhysicsRigidBodyAPI::GetSimulationOwnerRel ( ) const

Single PhysicsScene that will simulate this body. By default this is the first PhysicsScene found in the stage using UsdStage::Traverse().

USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::GetStartsAsleepAttr ( ) const

Determines if the body is asleep when the simulation starts.

Declaration uniform bool physics:startsAsleep = 0
C++ Type bool
Usd Type SdfValueTypeNames->Bool
Variability SdfVariabilityUniform
USDPHYSICS_API UsdAttribute UsdPhysicsRigidBodyAPI::GetVelocityAttr ( ) const

Linear velocity in the same space as the node's xform. Units: distance/second.
