usdrt::UsdShadeNodeGraph

Defined in usdrt/scenegraph/usd/usdShade/nodeGraph.h

Functions

usdrt::UsdShadeNodeGraph::Define: Attempt to ensure a UsdPrim adhering to this schema at path is defined (according to UsdPrim::IsDefined()) on this stage.
usdrt::DestructionSchemaDestructibleBaseAPI::GetPath: Return the SdfPath to this schema object's held prim.
usdrt::DestructionSchemaDestructibleBaseAPI::GetPrim: Return this schema object's held prim.
usdrt::UsdShadeNodeGraph::UsdShadeNodeGraph: Construct a UsdShadeNodeGraph on UsdPrim prim . Equivalent to UsdShadeNodeGraph::Get(prim.GetStage(), prim.GetPath()) for a valid prim , but will not immediately throw an error for an invalid prim .
usdrt::UsdShadeNodeGraph::UsdShadeNodeGraph: Construct a UsdShadeNodeGraph on the prim held by schemaObj . Should be preferred over UsdShadeNodeGraph (schemaObj.GetPrim()), as it preserves SchemaBase state.
usdrt::UsdShadeNodeGraph::operator bool: Boolean operator.
usdrt::UsdShadeNodeGraph::~UsdShadeNodeGraph: Destructor.

Variables

usdrt::UsdShadeNodeGraph::schemaType: Compile time constant representing what kind of schema this class is.

class UsdShadeNodeGraph : public usdrt::UsdTyped 

A node-graph is a container for shading nodes, as well as other node-graphs. It has a public input interface and provides a list of public outputs.

Node Graph Interfaces

One of the most important functions of a node-graph is to host the “interface” with which clients of already-built shading networks will interact. Please see Interface Inputs for a detailed explanation of what the interface provides, and how to construct and use it, to effectively share/instance shader networks.

Node Graph Outputs

These behave like outputs on a shader and are typically connected to an output on a shader inside the node-graph.

Public Functions

inline explicit UsdShadeNodeGraph(const UsdPrim &prim = UsdPrim()): Construct a UsdShadeNodeGraph on UsdPrim prim. Equivalent to UsdShadeNodeGraph::Get(prim.GetStage(), prim.GetPath()) for a valid prim , but will not immediately throw an error for an invalid prim.

inline explicit UsdShadeNodeGraph(const UsdSchemaBase &schemaObj): Construct a UsdShadeNodeGraph on the prim held by schemaObj . Should be preferred over UsdShadeNodeGraph(schemaObj.GetPrim()), as it preserves SchemaBase state.

inline virtual ~UsdShadeNodeGraph(): Destructor.

inline operator bool() const

Boolean operator.

Returns: Return true if the contained prim is an instance of this schema using IsA, and false otherwise.

UsdPrim GetPrim() const: Return this schema object’s held prim.

SdfPath GetPath() const: Return the SdfPath to this schema object’s held prim.

Public Static Functions
