July 21 2007 12:09:59.652 PM STRIPACK_PRB2 FORTRAN90 version A sample application of the data produced by STRIPACK. Here, we have STRIPACK compute the Voronoi diagram of a set of points on the unit sphere, and then we do a simple check by computing the polygonal area and summing. VORONOI_POLY_COUNT Number of polygons of each shape. Faces = 32 Vertices = 60 Edges = 90 F+V-E-2 = 0 Sides Number 3 1 4 4 5 7 6 15 7 4 8 1 VORONOI_TRAVERSE Visit each Voronoi polygon. Compute the (spherical) area of each subtriangle Add up to get the area of each polygon. 0.479216E-02 0.407071E-02 0.541308E-02 0.853653E-02 0.727773E-02 0.756908E-02 0.614709E-02 1 0.438064E-01 0.762278E-02 0.570281E-02 0.989282E-03 0.401129E-02 0.273480E-02 0.603281E-02 2 0.270938E-01 .695274 0.137617E-01 0.340515E-02 0.191463E-01 0.519497E-02 0.206620E-01 .222690 3 .980135 0.157329E-01 0.111011E-02 0.603281E-02 0.269308E-02 0.707325E-02 4 0.326421E-01 0.193260E-01 0.814912E-02 0.614709E-02 0.881274E-02 0.191463E-01 5 0.615813E-01 0.915721E-02 0.206620E-01 0.269198E-02 6 0.325111E-01 0.453306E-01 0.171114E-01 0.127255E-01 0.416258E-02 0.229770E-01 0.137617E-01 7 .116069 0.193318E-01 0.168434E-01 0.749343E-02 0.707325E-02 0.659661E-02 0.104168E-01 8 0.677553E-01 .966363 .353443 .392055 0.853653E-02 0.799264E-02 0.136041E-01 .237199 9 1.97919 0.108602E-02 0.931504E-02 0.126058E-01 0.104168E-01 0.142370E-02 0.106317E-01 10 0.454791E-01 0.519497E-02 0.881274E-02 0.756908E-02 0.369672E-02 0.269198E-02 11 0.279655E-01 .155749 0.157329E-01 0.749343E-02 .269308 12 .448283 0.306757E-02 0.138716E-02 0.514792E-02 0.474160E-02 0.407071E-02 13 0.184150E-01 0.137799E-01 0.136041E-01 0.453056E-02 0.570281E-02 14 0.376173E-01 .115192 .353443 1.09121 .399666 0.453306E-01 .695274 15 2.70012 0.358247E-02 0.432604E-02 0.145491E-02 0.735804E-02 0.540291E-02 16 0.221244E-01 0.272800E-02 0.633492E-02 0.156358E-03 0.346493E-02 0.142370E-02 0.659661E-02 0.269308E-02 0.273480E-02 17 0.261324E-01 0.313653E-02 0.993445E-03 0.258628E-02 0.842094E-02 18 0.151372E-01 1.09121 .966363 0.442683E-01 .269308 0.168434E-01 .103707 .590148 19 3.08185 0.204534E-02 0.514792E-02 0.456238E-02 0.272800E-02 0.401129E-02 20 0.184949E-01 0.367798E-03 0.633492E-02 0.456238E-02 0.138716E-02 0.351953E-02 0.540291E-02 21 0.215747E-01 0.799264E-02 0.541308E-02 0.474160E-02 0.204534E-02 0.989282E-03 0.453056E-02 22 0.257125E-01 0.351953E-02 0.306757E-02 0.479216E-02 0.814912E-02 0.534367E-02 0.358247E-02 23 0.284545E-01 0.384954E-02 0.156358E-03 0.367798E-03 0.735804E-02 0.221121E-02 0.993445E-03 24 0.149364E-01 0.534367E-02 0.193260E-01 0.340515E-02 0.229770E-01 0.724036E-02 0.432604E-02 25 0.626183E-01 0.771510E-01 .103707 0.193318E-01 0.126058E-01 26 .212795 0.162102E-01 0.108602E-02 0.455833E-02 0.842094E-02 0.609008E-02 0.127255E-01 27 0.490911E-01 .115192 .222690 0.915721E-02 0.369672E-02 0.727773E-02 .392055 28 .750069 0.221121E-02 0.145491E-02 0.724036E-02 0.416258E-02 0.609008E-02 0.258628E-02 29 0.237454E-01 0.455833E-02 0.106317E-01 0.346493E-02 0.384954E-02 0.313653E-02 30 0.256411E-01 0.442683E-01 .237199 0.137799E-01 0.762278E-02 0.111011E-02 .155749 31 .459729 .590148 0.771510E-01 0.931504E-02 0.162102E-01 0.171114E-01 .399666 32 1.10960 Sphere area from Voronoi polygons = 12.566371 Exact area from spherical geometry = 12.566371 STRIPACK_PRB2: Normal end of execution.
