Stanford Bunny

The Stanford Bunny is a computer graphics test model (GTM) for 3-D graphics. The Bunny is a data-set for constructing digital, three dimensional models. The original model for the Bunny was a clay rabbit figure. The data from the clay rabbit was collected by using a technique called range scan that was developed by Greg Turk of Georgia Institute of Technology and Marc Levoy of Stanford University. 

In a range scan, the color or shade of each pixel represents a specific radial distance, technically known as range, from the observer's point of view. Mathematically, the range scan of the original clay rabbit is a collection of 69,451 triangles. The paper version below is a simple illustration of how a programmer might use shade data from a range scan to re-create the bunny.

In a range scan, radial distances can be portrayed as colors of the spectrum in a red-green-blue ( RGB ) image or as levels of brightness in a grayscale image. In a color range scan, for example, the shortest ranges might be rendered as white, progressing through the colors of the spectrum according to decreasing wavelength -- red, orange, yellow, green, blue, indigo and violet -- as the range increases, with maximum or infinite range represented as a black background. A grayscale range scan might portray the shortest ranges as white, with increasing ranges as progressively darker shades of gray until the background, at infinite range, is rendered as black. When a real-world three-dimensional ( 3D ) solid object is scanned in this way, the resulting image resembles a false-color or false-grayscale photograph.

The Stanford Bunny is the oldest and best-known of a collection of models in the Stanford 3D Scanning Repository. Other models include a drill bit, an armadillo, an angel, a dragon and a Buddha.
