class UsdPhysicsPrismaticJoint : public usdrt::UsdPhysicsJoint#
Predefined prismatic joint type (translation along prismatic 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 UsdPhysicsPrismaticJoint( )#
Construct a UsdPhysicsPrismaticJoint on UsdPrim
prim
. Equivalent to UsdPhysicsPrismaticJoint::Get(prim.GetStage(), prim.GetPath()) for a validprim
, but will not immediately throw an error for an invalidprim
.
- inline explicit UsdPhysicsPrismaticJoint(
- const UsdSchemaBase &schemaObj,
Construct a UsdPhysicsPrismaticJoint on the prim held by
schemaObj
. Should be preferred over UsdPhysicsPrismaticJoint(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.

token visibility = "inherited"

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.

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 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.

- Returns:
True if the help prim is valid, and the schema object is compatible with its held prim.
Public Static Functions
- static inline UsdPhysicsPrismaticJoint Define(
- const UsdStageRefPtr &stage,
- const SdfPath &path,
Attempt to ensure a UsdPrim adhering to this schema at
path
is defined (according to UsdPrim::IsDefined()) on this stage.

Protected Functions
-
inline virtual bool _IsCompatible() const#
Helper for subclasses to do specific compatibility checking with the given prim. Subclassess may override
_isCompatible
to for example check type compatibility or value compatibility on the prim.Overrides exist for UsdTyped and UsdAPISchemaBase.
This check is called when clients invoke the bool operator.
- Returns:
True if the schema object is compatible with its held prim.
