Guan Yu - specularity research project

General Guan Yu on Horseback, 16th C CE, now in the collection of the Minneapolis Institute of Art. More info about the object on [artsmia.org](https://collections.artsmia.org/art/31065/general-guan-yu-on-horseback-china) This model was scanned and produced with a research process to capture surface texture and specularity more accurately - the research has been headed up by Michael Tetzlaff, Assistant Professor of Computer Science at the University of Wisconsin-Stout, as part of a research effort that began when Michael was a doctoral student in Computer Science at the University of Minnesota. The research process includes two unique components compared to our regular photogrammetry process: the light source for the source images is very close to the camera's point of view; and Michael's custom software uses those source images to capture and reproduce the actual specularity of the object.
