Three-dimensional mesh geometry of the SHAPE model as seen from two orthogonal directions. The left panel shows the side view along the observer’s direction, and the right panel shows the front view facing the observer. The red torus represents the EDE, and the peanutshaped blue structure represents the EE. The inner and outer radii of the EDE are assumed to be 0.78 and 1.75″, respectively. The major axis of the EE is assumed to be 2″.
