FREEship_version_2.6_win32_executable 船舶避碰方面的开源软件

   *  Insert multiple points in one pass by intersecting visible edges with a 3D plane
   *  Lock/unlock points
   *  Modified the developability-shading procedure by lowering the value used to test for developability
      so that it produces less noise
   *  Extended the current hydrostatic calculations and modified the output format

Version 1.91
Released September 08, 2005
   *  Major modification to the file format and file extension. FREE!hip models are from
      now on stored as binary files. This reduces the average filesize (and undo memory) to
      approx. 40 percent. This modification is done in preparation for web distribution of
      FREE!ship models (user database) and for the inclusion of a preview thumbnail in the file.
      The extension if the files is modified from .free to .fbm (Freeship Binary Model) Old
      files can still be imported but saving in the old FREE!ship file-format is no longer
      supported.
   *  Monochrome drawing of linesplan
   *  If no diagonals are present in the model, the plan view can optionally
      be mirrored in the linesplan, so that both port and starboardside are visible
   *  New startup screen
   *  Export the formatted linesplan to an AutoCad dxf file (lines only, no fill colors used)
   *  Added comment and file-creator fields to project settings dialog
   *  Import of XYZ files describing longitudinal chines, created with Carene
   *  Added dimensioning of unfolded parts to the developed plates window
   *  Enabled manual input of the rotation angle of unfolded plates
   *  Updated imperial coordinate input
   *  Save viewports as bmp image
   *  Select/deselect edgeloops by ctrl-clicking an edge
   *  Fixed bug which caused faces created by edge-extrusion to be assigned to another
      layer then the currently active layer
   *  Only shade the submerged surfaces in another color if the layer is also used for hydrostatics
   *  Import and interpolate a surface defined as a number of curves in a textfile
   *  Curvature plot of intersectionlines
   *  Added material properties to layers used to calculate weight of the surface area of a layer
   *  Program remembers settings of the intersection dialog
   *  Separate save and saveas functions
   *  Shading of submerged parts on the linesplan is turned of when it is disabled in the projectsettings. 

Version 1.80
Released August 18, 2005
   *  Export stations now also to Archimedes (single body) in addition to
      ArchimedesMB (ref. manual section 3.5.6)
   *  Improved Archimedes export routine by merging stations containing multiple
      segments into one larger station (ref. manual section 3.5.6)
   *  Modified selecting procedure of controlpoints. Selecting multiple
      controlpoints from this release and on is done by keeping the ctrl-key
      pressed. If not, then only 1 controlpoint is selected at a time. (ref.
      manual section 2.2)
   *  Input relative values and imperial units in the controlpoint form (ref.
      manual section 2.4)
   *  Extra buttons and layer properties in layer properties dialog (ref.
      manual section 9.8)
   *  Keep as much from the original data when assigning faces to new layers
      using the autogroup function
   *  Improved unfolding routine, highlight edges which are stretched or compressed
      and added intersection with diagonals (ref. manual section 12.3)
   *  Linesplan view added (ref. manual section 4.2)
   *  Diagonals added to intersection lines. (ref. manual section 13.1)
   *  Delete all intersections in one pass from intersection dialog
   *  Printing from multiple windows (ref. manual section 2.6)
   *  Program now gives a warning when the current model has been changed and a
      new one is about to be loaded
   *  Created a dialog to control the image size when saving data to a bitmap
   *  Added list with recently opened files to the menu for faster acces
   *  Drawing of leak points in a different color (ref. manual section 12.1)

Version 1.70
Released July 29, 2005
   *  Unfold Develop plates
   *  After auto-group of layers, the proper active layer is displayed
   *  When importing a .hul file, one new layer is created between two subsequent chines
      and one layer for faces which are added to close the hull at the centerline
   *  Store separate (last used) paths for import, export, save or load files
   *  Export stations to ArchimedesMB
   *  Implemented different shading modes

Version 1.65
Released July 14, 2005
   *  Set decimal seperator to a point.
   *  Fixed some minor points on .hul input
   *  Remember settings from hydrostatics dialog
   *  Fixed shading of underwaterview when the lowest part of the hull was not on
      Z=0.0 plane (height of waterline was incorrect)
   *  Model-check routine now also indicates location of leak points.
   *  Automatic model-checking can be swtched off in ptojectsettings dialog.
   *  When a new default model is started the user can also specify if the project
      should use metric or imperial units.
   *  Information exported to a DXF file is the same as what is seen on screen.
   *  3D translation of the entire model
   *  Mainframe location is also adapted when the model is scaled or moved
   *  Bug fixed that occurred when first a point was selected in a orthogonal view
      and secondly an edge was selected. The selected point then incorrectly moved
      to a new location.
   *  Manual add a new point in 3D space.
