As the last example, the discretization of Stanford bunny is presented (Fig. 13). Again, three control grids containing 11721, 27972, and 59333 elements, respectively, have been used to triangulate the body of the bunny, this time, however, with curvature-based element size control. The adopted projection strategy including the limit tolerances is the same as in the case of concrete dam in the previous subsection. The relation of the total computational time and the number of generated elements for individual control meshes (Fig. 12) is very close to linear and the mesh generation phase is almost independent of the density of the control grid. However total elapsed time for the meshes generated over the coarsest control grid is slightly larger, which is caused by larger overhead in the ``exact'' projection during the last smoothing cycle due to the increased number of correction cases.
