Model SC-369 of the Harvard Museum of Comparative Zoology Collection of Blaschka Marine Invertebrates. This glass model is one of thousands made by Rudolf and Leopold Blaschka in the late 1800s as educational models. The EOL page (http://eol.org/pages/448835/overview) states that this species of Cuttlefish (labeled by the Blaschkas as Sepia bisserialis, but currently known as Sepia elegans), never larger than about 3.5 inches, is found in the Mediterranean and in the Eastern Atlantic from Scotland in the north to the west coast of Africa in the south.
The 3D model was made from 365 photographs using Agisoft Photoscan. In addition to glass the Blaschkas used other materials. For this cuttlefish the dorsal surface was made of painted paper. This thin surface posed a challenge for the photogrammetry alignment and required careful masking of the photos prior to processing. Blender was used to assign four sets of material properties to the dorsal area, the remainder of the body, the tentacle and the eyes.
