A modified “Stanford Bunny” model (courtesy of Yutaka Ohtake of Max-Planck-Institut fuer Informatik).. (a) Original (source) data: 10526 vertices, 20835 polygons. (b) Yellow area: the area WR to be retouched (930 vertices), (c) Yellow area (height data), which defines the vertices used for interpolation (807 vertices). (d) The same surface after retouching. Processing time in our test configuration (AMD Athlon 1000 Mhz, 128 MB RAM, Microsoft Windows 2000): 1 sec, compact matrix size 1139180 bytes, selected radius of support: r = 0.2.
