The outer wall of the aneurysm is modeled in a semi-transparent blue so that it is possible to see the diameter of the patent portion of the aorta through which the blood still flows. Propulsed endoscope Computer visualization tools were employed to illustrate the geometry and function of an experimental self-propelled endoscope for evaluating intestinal ulcers and cancer. The device moves by selectively inflating and deflating the front, middle, and rear sections. The animation is created by interpolating between a collection of 3D geometric models at different stages in the cycle of inflation and deflation. In the second portion of the animation, the outer layers of the endoscope are peeled away to reveal the inner components.
Reflection mapping is used to produce the polished appearance of the metallic components.
