Stanford BunnyFor 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 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.
