Once again, a lot of new features for this release:
  • New version numbering scheme:
    • version 2.X.Y (from now on the third digit will replace the release date)
    • this version number will be common to all platforms (Windows, Mac OS and Linux) and will correspond to a 'tagged' version on github
  • New tool: "Cross section" (clipping box)
    • accessible via the 'Tools > Segmentation > Cross Section' menu entry or via a dedicated icon in the main toolbar (next to the scissors icon)
    • manually scale, rotate and translate the clipping box
    • extract the corresponding selection as a new cloud
    • extract multiple slices in an automated way ('Repeat' mode)
    • works only with clouds for the moment
  • New DB tree context menu option: "Align camera" (on a plane or a label)
    • right clik on a plane primitive or a triangle label (use the "Picking point" tool to create them on clouds, or SHIFT+left click on any mesh face)
      • choose 'Align camera' to make the camera look perpendicularly to it
      • same thing with 'Align camera (reverse)' (to look in the opposite direction)
  • New option for ICP registration (thanks to Luca Penasa once again!):
    • check the "Free scale parameter" checkbox to register objects with different scales
  • New dialog for computing the octree:
    • the user can specify the cell size at the maximum subdivision level
    • or define a custom bounding box
  • "Height grid generation" dialog enhanced:
    • the user can now define custom grid limits (same dialog as for the octree - see above)
    • the tool now spawns dialogs to let the user specify the ouput files (ascii grid, image, etc.)
  •  New tool: "Convert RGB to scalar field"
    • See 'Edit > Colors' menu
  • New option in ASCII file load/save dialogs:
    • maximum number of points per cloud on load
    • option to write the number of points as a dedicated header line when saving
  • Menus modifications:
    • "Primitive factory" menu entry has been moved to the "File" menu
    • "Point picking" and "Point list picking" menu entries have been moved to the "Tools" menu
    • "Edit" and "Tools" menus are now always enabled even if no entity is selected
  • The (old) limit of 128 million points per cloud has been removed on the 64 bits version
    • new theoretical limit is 2 billion points ;)
  • Global shift information can now be edited
    • See the 'Edit > Edit global shift' menu entry
  • LAS import/export enhanced:
    • new dialog to choose the fields to import
    • all official fields are now properly imported/exported:
      • Intensity
      • Return Number
      • Number of Returns
      • Scan Direction
      • Flightline Edge
      • Classification
      • Scan Angle Rank
      • User Data
      • Point Source ID
      • Red
      • Green
      • Blue
      • Time
    • the 'classification' field can now be split into its true 'value' and the 3 associated flags ("Synthetic", "Key-point" and "Withheld")
    • a warning is issued if the user attempts to save a cloud with SFs having non "official" names
  • Stippling (fake transparency) option has been added to meshes
  • ccViewer enhanced:
    • GUI updated (pivot visibility options added, isometric default views, new icons, etc.)
    • PDMS format support added
    • 3D mouse support added
  • Misc. improvements:
    • new icon for the 'clone' method (thanks to JF Hullo): two sheeps instead of one!
    • when computing local density, if two or more points are overlapping, the result density will be 'NAN' and the point will appear in gray (in order to be hidden or removed easily)
    • global shift information is now kept by qRansacSD plugin (shape detection)
    • qHPR (Hidden Point Removal) plugin now generates a new cloud with the visible points only (instead of hacking the points visibility) along with the corresponding viewport
    • scaled transformation matrix are now properly inversed (i.e. scale is taken into account)
    • point-pair based alignment tool outputs a summary on completion (RMS, scale, etc.)
    • scale estimation during point-pair based alignment has been enhanced
  • Bug fixes:
    • applying the interactive 'rotate/translate' tool to an entity and its parent at the same time would make CC crash
    • "Intensity", "Time" and "Return number" fields are now properly exported with LAS files
    • "Height Grid Generation" tool accuracy fixed (when dealing with coordinates above 10^5)
    • mesh with a single texture AND colors couldn't be saved properly in PLY format (CC would refuse to save the texture)
    • deleting a child object (e.g. labels) in ccViewer would make it crash!
    • old viewports (prior to version 25) were wrongly imported (panning info)
    • deleting groups containing clouds used by shared labels would make CC crash

You'll also find the new ccViewer versions here:
