Stanford bunny

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.^[1] This figurine and others were scanned to test methods of range scanning physical objects.^[2]

The Stanford bunny

The data can be used to test various graphics algorithms, including polygonal simplification, compression, and surface smoothing. There are a few complications with this dataset that can occur in any 3D scan data: the model is manifold connected and has holes in the data, some due to scanning limits and some due to the object being hollow.^[3] These complications provide a more realistic input for any algorithm that is benchmarked with the Stanford bunny,^[4] though by today's standards, in terms of geometric complexity and triangle count, it is considered a simple model.

The model was originally available in .ply (polygons) file format in four different resolutions.^{[citation needed]}
