Functions

Variables

class UsdPhysicsRevoluteJoint : public usdrt::UsdPhysicsJoint

Predefined revolute joint type (rotation along revolute joint axis is permitted.) For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdPhysicsTokens. So to set an attribute to the value “rightHanded”, use UsdPhysicsTokens->rightHanded as the value.

Public Functions

inline explicit UsdPhysicsRevoluteJoint(const UsdPrim &prim = UsdPrim())

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

inline explicit UsdPhysicsRevoluteJoint(const UsdSchemaBase &schemaObj)

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

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"

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

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.
