The resulting scan data are available here and look like this:

The actual cell-decomposition I use for pictures comes from a project to automatically generate cut-out sheets for paper models. Here is the relevant research paper and here is the paper model:

Researches in computer graphics continue to always find new ways to do horrible things to the bunny. Here are just a few examples:
