Kintsugi 3D: emerging software for realistic specular photogrammetry

Kintsugi 3D Builder is an emerging open-source tool that produces realistic specularity maps from photogrammetry, leveraging camera-mounted flash lighting. Although specularity can be manually added to the textures produced by conventional photogrammetry, this empirically based approach is unique in that it offers a solution for producing a complete material model derived entirely from photographs. Kintsugi 3D Builder works by reconstructing color in terms of physical light reflectance, rather than merely stitching together photographs, which mitigates issues that would otherwise occur with the camera-mounted flash workflow such as baked in shadows or highlights.Kintsugi 3D Builder is primarily used right now in the cultural heritage sector and is currently in use at several significant museums around the country including the Minneapolis Institute of Art. However, we also believe it has untapped potential for game development workflows to produce more realistic photogrammetric materials in less time.

Kaelie Tetzlaff is an Associate Professor of Computer Science at the University of Wisconsin – Stout with seven years of experience teaching game design courses at the undergraduate level. Tetzlaff received a B.S. in Computer Science from Bethel University in St. Paul, and a M.S. and Ph.D. in Computer Science from the University of Minnesota. She is the development lead for Kintsugi 3D, an open-source software project to support heritage photogrammetry with improved color appearance accuracy. Her research and creative interests include computer graphics and game design education and applications of computer graphics in cultural heritage.
