Detailed Description

Abstract interface for querying and mutating a material network.

This is useful for implementing matfilt functions which can be reused by future scene index implementations.

NOTE: Subclasses make no guarantee of thread-safety even for the const accessors as they might make use of internal caching for optimization. Should you want to read from a material from multiple threads, create a thread-specific interface instance. The non-const methods should never be considered thread-safe from multiple interface instances backed from the same concrete data.

Member Function Documentation

◆ GetNodeTypeInfoKeys()

virtual TfTokenVector GetNodeTypeInfoKeys ( const TfToken &  nodeName) const
pure virtual

Node type info is a collection of data related to the node type, often used to determine the node type.

For now, we only have getters for this, as we aren't really intending on mutating this in any filter.

Implemented in HdDataSourceMaterialNetworkInterface, and HdMaterialNetwork2Interface.

◆ GetTerminalNames()

virtual TfTokenVector GetTerminalNames ( ) const
pure virtual

Terminal query & mutation

Implemented in HdDataSourceMaterialNetworkInterface, and HdMaterialNetwork2Interface.
