Early last summer, YDC2 worked with the post-docs to image a bust of Alexander Pope by Louis Francois Roubiliac (see our post– Have 3D scanner, will travel). On February 6, the YDC2 Imaging Lab, along with the Computer Science department, continued the collaboration with the Yale Center for British Arts (YCBA) on the second part of this project.
The YCBA was planning a new exhibit: Fame and Friendship: Pope, Roubiliac and the Portrait Bust of Eighteenth Century Britain. Louis Francois Roubiliac produced eight sculptural representations of Alexander Pope which are now spread out among different collections around the world. This exhibit would be the first time all eight busts would be together in approximately 50 years. The YCBA requested the application of 3D laser scanning to yield digital replicas in the hopes of determining the chronology of the creation of the busts. The 3D models would not only give researchers surface geometry but also dimensions of Pope’s features and how the tool mark placement varied between busts.
As the busts could not travel to the Imaging Lab, Jessica Slawski, Chelsea Graham, and Ying Yang set up the ShapeGrabber 3D laser scanning equipment in the YCBA. Chelsea, along with Ruggero Pintus and Ying Yang, Postdoctoral Fellows for the Computer Science department, began scanning the busts on February 6. Once the busts were unpacked, they were photographed by YCBA staff. After their photo shoot, the busts then began the 3D scanning process which took about 4 hours per bust. When this process was complete, the busts were moved to the exhibit area to be installed. Due to time constraints, only 4 of the busts were able to be 3D scanned before they were installed for the exhibit. The hope is that the remaining 4 busts will be imaged during the exhibit de-installation. The post processing of these 3D models will take up to 30 hours per bust. Once the models are done, researchers will be able to overlay the models on top of each other to compare features and tool marks.
