  The Stanford Bunny
The Stanford Bunny is one of the most commonly used test models in computer graphics.
I was a postdoc at Stanford University with Marc Levoy in 1993 and 1994.
The bunny is so smooth that there is a lot of redundant information in the original collection of triangles, so simplification and compression algorithms give wonderful results.

The physical bunny has a correct handed-nes, and if you want the index space of the volume to be right handed, then the flip is needed.

This image is from an interactive demo of our new discrete collision detection approach for large-scale environments, in which the Stanford dragon (250,000 triangles) breaks when the Stanford bunny (35,000 triangles) falls on it.
The dragon is organized in triangle strips and a heuristic is used to remove some strips and propagate the fracture when the bunny collides the dragon.
Since no penetration depth is computed, the velocity of the contact point on the bunny is used as the contact normal.

 Model: Stanford Bunny   (Site not responding. Last check: 2007-10-13)
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.

(Many other people have developed similar codes, such as Konrad Polthier or Vladimir Oliker.) The geodesics all emanate from a point between the ears of the bunny, so any intersection might be a point on the cut locus of that point (if the two geodesics were the same length).

 Ray / Tri-Mesh Intersection Benchmark
The test is as follows: Randomly generate a ray origin point on the surface of the sphere of radius 0.2 centered on the point (-0.016840, 0.110154, -0.001537), which happens to be the center of the bunny axis-aligned bounding box.
With sufficiently efficient ray/mesh intersection code, the time spent generating the random points on the unit sphere required by the benchmark becomes a significant fraction of the total time.
Check that the bunny axis-aligned bounding box has minimum coords (-0.094690,0.032987,-0.061874), maximum coords (0.061009,0.187321,0.058800), and center (-0.016840,0.110154,-0.001537).

 Triangle Strip Tunneling Algorithm Experiments on the Stanford Bunny have shown that the depth can be limited to about 75 edges without substantially affecting the quality of the resulting stripification.
In addition, tunnel searches should be performed starting from some of the other strip ends in the mesh, since a topological change or even the changes caused by tunneling may allow other tunnels to be found where none existed before.
A sequence of 5,000 topology-changing operations was performed upon a 20,000-face version of the Stanford Bunny.

 Paper Bunny
The research site linked to a free viewer that can be used for printing out 3D paper craft models, which worked with a bunny.zip file they had of the Stanford Bunny converted to their strip-based paper craft method.
You can click on strips of the 3D bunny on-screen through the viewer and it shows you the corresponding strip on the laid-out sheets of paper, which you see in the right pane of the viewer.
This is extra cool, because while building it, even though I was using the 3D viewer, and could see exactly what the piece was used for, it still had this feeling of being totally random.

As you can see the G80 is twice as big, which is a good indication it requires twice the power, and produces twice the floating point power on paper.
However when we ran one of the benchmarks discussed in the paper, the Stanford Bunny, we found that the Cell processor when combined with the iRT produces significantly better performance (we don't have access to the other datasets listed in the paper):
In fact one Cell processor is four to five times faster at ray-tracing the Stanford Bunny than the G80 and the Cell QS20 blade, which has comparable floating point power on paper, is eight to eleven times faster.
