source: code/branches/core4/src/orxonox/tools/Mesh.cc @ 4073

Last change on this file since 4073 was 3265, checked in by rgrieder, 15 years ago
  • Removed superfluous convertToString and convertFromString (replaced them with multi_cast)
  • Replaced all getConvertedValue with multi_cast since it doesn't involve a potential implicit cast of the argument (template type deduction always leads to the right type)
  • Using NilValue<T>() instead of zeroise<T>() for better performance (detail, but just caught my eye)
  • Property svn:eol-style set to native
