Detailed Description

a collection of materials for ANARI-based rendering

A singleton instance of this class manages a collection of materials for use with the ANARI renderer. The materials can be read in from disk or created programmatically.

This class extends vtkRenderMaterialLibrary with ANARI-specific material type validation and the ANARI material parameter dictionary. It accepts material files with the "ANARI" family designation.
