For this case, the classic Stanford bunny geometry has been sliced into 5 disconnected surfaces with significant
parts of the original surface missing. Traditional hole filling will not work in this case as there are no closed
boundary loops linking the different surfaces. DGK provides two strategies for this repair - manual surface
construction and wrapping. Each of these strategies are used in conjuction with refinement and blending in
order to get the final result. Finally, angle based coarsening is applied to the original bunny model. A tutorial
video of this case is available on the videos age.
