Web3D technologies provide interactive ways to present scientific data, including 3D models from archaeometric surveys, and offer new possibilities for accessing and examining artwork. We will present aWeb3D/WebXR tool for inspecting multi-layered 3D assets, enabling interactive discovery, semantic enrichment, and efficient spatial queries. The tool also integrates AI-generated material assets into the web3D technology stack, enhancing applications and enabling immersive material reconstructions for cultural heritage experts and researchers.enBranche: Cultural and Creative EconomyResearch Line: Computer graphics (CG)Research Line: Computer vision (CV)Research Line: Human computer interaction (HCI)Research Line: Machine learning (ML)LTA: Generation, capture, processing, and output of images and 3D models3D Reconstruction3D RenderingAppearance estimationSegmentationSemantic shadingpaper
