Last change on this file since a80fbdf was 357fba, checked in by Frederik Heber <heber@…>, 16 years ago

Huge refactoring of Tesselation routines, but not finished yet.

  • new file tesselation.cpp with all of classes tesselation, Boundary..Set and CandidatesForTesselationOB
  • new file tesselationhelper.cpp with all auxiliary functions.
  • boundary.cpp just contains super functions, combininb molecule and Tesselation pointers
  • new pointer molecule::TesselStruct
  • PointMap, LineMap, TriangleMap DistanceMap have been moved from molecules.hpp to tesselation.hpp
  • new abstract class PointCloud and TesselPoint
  • atom inherits TesselPoint
  • molecule inherits PointCloud (i.e. a set of TesselPoints) and implements all virtual functions for the chained list
  • TriangleFilesWritten is thrown out, intermediate steps are written in find_nonconvex_border and not in find_next_triangle()
  • LinkedCell class uses TesselPoint as its nodes, i.e. as long as any class inherits TesselPoint, it may make use of LinkedCell as well and a PointCloud is used to initialize
  • class atom and bond definitions have been moved to own header files

NOTE: This is not bugfree yet. Tesselation of heptan produces way too many triangles, but runs without faults or leaks.
  • Property mode set to 100755
