Here are a few images of models and the results of the Loop and butterfly
subdivision. Note that the Loop subdivision surfaces will generally appear
smooth but may shrink a little bit. The butterfly subdivision will not shrink,
but will be of poorer quality, especially if there are a lot of vertices of low
degree and high degree in the mesh (Butterfly is smooth only for degrees between
4 and 7). Other reasonable input files are the pawn, pig and shark from project
2.
