Stanford Bunny 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.

The broken bunny with free curves highlighted. 
The chest of the bunny.  Two new curves  (shown in blue) have been created to bridge the  gap between the two surfaces. 
A new surface is created using the four curves  as boundary.
Direct refinement (no projection or smooth  surface reconstruction) is performed. The size  is interpolated from the boundary of the  surface.
The bunny after all surfaces constructed,  refined and blended. The blending operation  has created a smooth transition between the  new and original surfaces.
