The Stanford Bunny model was originally constructed in 1994 by Greg Turk and Marc Levoy using a technique they developed to create polygonal models from range scans (see their paper). The Bunny model they created consisted of exactly 69,451 triangles; we are using this model in our rendering server. There are five holes in the Bunny model: three of these were the result of inadequate coverage when scanning, and the two circular holes on the base existed on the physical Bunny, which was hollow.
The Stanford Bunny has become one of models most commonly used in testing computer graphics techniques. You can visit the Bunny's website for more information and pictures.
