Tutorial #10: ASAM OpenMATERIAL 3D Material Mapping

In this video, Clemens, CTO of Persival, demonstrates how to map physical material properties to 3D geometries using the ASAM OpenMATERIAL 3D standard. Building on the previous tutorial about defining materials, Clemens shows how to link those definitions to actual 3D models, enabling realistic, sensor-ready simulation environments.

Key Topics Covered

• Asset and Mapping Files Explained: Learn how .xoma (asset) and .xomm (material mapping) files connect 3D model materials to physical property definitions in .xomp files.

• Material Name Matching: See how material names like “paint red” or “rubber black” in 3D models (e.g., glTF files) are used to map to standardized material definitions, ensuring consistency across simulation assets.

• Visualizing Material IDs in Simspector: Explore how Persival’s Simspector tool highlights and identifies materials in a scene using UUIDs, allowing users to inspect and verify material mappings interactively.

• Flexible Yet Consistent Mapping: Understand how different naming conventions across assets can still be unified through mapping files and why consistent naming improves efficiency.

• Trace-Driven Integration: Discover how a single OSI trace file can reference all necessary components, geometry, asset metadata, material mappings, and physical properties, creating a fully integrated simulation pipeline.
