Detailed Description

Adds simulation material properties to a Material. All collisions that have a relationship to this material will have their collision response defined through this material.

Constructor & Destructor Documentation

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

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

Definition at line 71 of file materialAPI.h.

UsdPhysicsMaterialAPI::UsdPhysicsMaterialAPI ( const UsdSchemaBase schemaObj)
inlineexplicit

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

Definition at line 79 of file materialAPI.h.

virtual USDPHYSICS_API UsdPhysicsMaterialAPI::~UsdPhysicsMaterialAPI ( )
virtual

Destructor.

Member Function Documentation

USDPHYSICS_API UsdSchemaKind UsdPhysicsMaterialAPI::_GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind

Reimplemented from UsdAPISchemaBase.

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

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

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

UsdPrim::HasAPI()

UsdPrim::RemoveAPI()
static USDPHYSICS_API bool UsdPhysicsMaterialAPI::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 UsdAttribute UsdPhysicsMaterialAPI::CreateDensityAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetDensityAttr(), 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 UsdPhysicsMaterialAPI::CreateDynamicFrictionAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetDynamicFrictionAttr(), 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 UsdPhysicsMaterialAPI::CreateRestitutionAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetRestitutionAttr(), 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 UsdPhysicsMaterialAPI::CreateStaticFrictionAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetStaticFrictionAttr(), 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 UsdPhysicsMaterialAPI UsdPhysicsMaterialAPI::Get ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Return a UsdPhysicsMaterialAPI 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:

UsdPhysicsMaterialAPI(stage->GetPrimAtPath(path));
USDPHYSICS_API UsdAttribute UsdPhysicsMaterialAPI::GetDensityAttr ( ) const

If non-zero, defines the density of the material. This can be used for body mass computation, see PhysicsMassAPI. Note that if the density is 0.0 it is ignored. Units: mass/distance/distance/distance.

Dynamic friction coefficient. Unitless.

static USDPHYSICS_API const TfTokenVector& UsdPhysicsMaterialAPI::GetSchemaAttributeNames ( bool  includeInherited = true)

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 UsdAttribute UsdPhysicsMaterialAPI::GetStaticFrictionAttr ( ) const

Static friction coefficient. Unitless.
