The Stanford bunny is a computer graphics 3D test model developed by Greg Turk and Marc Levoy in 1994 at Stanford University. The model consists of 69,451 triangles, with the data determined by 3D scanning a ceramic figurine of a rabbit. This figurine and others were scanned to test methods of range scanning physical objects.

The model was originally available in .ply (polygons) file format in four different resolutions.

The original unprintable model can be found at https://graphics.stanford.edu/data/3Dscanrep/.
