v2.5.2 12/19/2013

  • GDAL library support added:
    • CC can now load dozens of standard GIS 2D1/2 raster formats (Arc Grid, GeoTiff, etc.)
  • 'Height grid generation' tool enhancement:
    • when selecting the 'min' or 'max height' projections, the user can now choose
      to 'resample' the original cloud in order to produce a new cloud (instead
      of generating a regularly sampled cloud using the grid cell's centers)
    • the tool can now export the resulting grid as a true multiband raster (geotiff)
    • menu entry renamed: "Tools > Projection > Rasterize (Height grid generation)"
  • It is now possible to compile CloudCompare with 64 bits floating point values
    (i.e 64 bits 'doubles' instead of 32 bits 'floats') for coordinates and/or scalars.
    It doubles the memory consumption but it increases a lot the accuracy.
    Moreover there's absolutely no loss of information when importing/exporting clouds
    with very big coordinates (however OpenGL still requires rather small coordinates
    for a proper display, therefore the 'shift on load' mechanism might still be necessary)
  • New tool: 'Display > Adjust zoom'
    • let the user set the current window zoom either directly or by specifying a pixel
      size in the (implicit) units of the current entities.
  • New tool: Edit > Scalar fields > Set SF as coordinate(s)
    • allows the user to map a scalar field to one or several dimensions (X,Y or Z)
    • useful to convert a 2D raster with a scalar field (gray level, etc.) to a 2D1/2 point cloud
  • New method: File > Close all
    • to remove all loaded entities
  • New formats:
    • Autodesk(R) FBX (http://en.wikipedia.org/wiki/FBX)
      • meshes only
      • support for materials is planned but not finished yet
    • Any geo-localized raster (geotiff, ArcGrid, etc.) thanks to GDAL library (http://www.gdal.org/)
      • on input: use 'File > Open' (raster will be converted to a point cloud)
      • on output: use the Height Grid Generation tool (this way, any cloud can be converted to raster)
  • New plugin: qSRA (Surface of Revolution Analysis)
    • for comparison between a point cloud and a surface of revolution
    • generates a map of deviations (with cylindrical or conical projection)
    • exports resulting map as an image, a textured mesh or a point cloud
    • can generate vertical and horizontal profiles in DXF format
  • Other enhancements:
    • the qPoissonRecon plugin is now based on the latest version of PoissonRecon (5.5)
    • the 'Edit > Transformation' tool now offers 3 different ways to input a transformation:
      • classical 4x4 transformation matrix
      • rotation axis, rotation angle and translation vector
      • Euler angles and translation vector
    • if you paste a transformation matrix copied from the console, the 'Edit > Transformation' tool will now automatically remove the timetsamp (between square brackets)
    • when using 'Local models' when computing cloud-to-cloud distances, CC will now take the smallest distance between each point and either the local model or the nearest neighbor
      (in order to avoid clearly erroneous distances due to badly shaped local models).
    • the 'facet' entity's normal vector can now be displayed or hidden via the facet properties
    • BIN file loading/saving is now performed in a separate thread
      • a progress dialog is now displayed during loading/saving
      • multiple loading sessions can be done concurrently (use drag & drop on a 3D view
        • note: only interesting when loading files from different drives)
      • additional check addded to detect corrupted meshes
    • Global rescaling applying at loading time is now properly handled
      • works just like global shift
      • appears in the entity properties as well
      • dedicated menu entry (Edit > Edit global scale)
    • pause button added to the "Graphical Transformation" tool (to allow rotating/panning the 3D view)
    • new shortcuts added to the "Graphical Transformation" tool:
      • space bar = pause/unpause
      • return key = apply transformation (close the tool)
      • escape key = cancel transformation (close the tool)
    • new shortcuts added to the "Graphical Segmentation" tool:
      • space bar = pause/unpause
      • tab key = switch between polygonal and rectangular selection mode
      • I key = segment points inside
      • O key = segment points outside
      • return key = apply segmentation (close the tool)
      • delete key = apply segmentation and delete hidden points (close the tool)
      • escape key = cancel transformation (close the tool)
    • New types of entities can now be cloned:
      • polylines
      • facets
    • Max coordinate absolute value lowered (100.000 instead of 1.000.000)
      in order to avoid accuracy loss and display issues. However the user
      still has the choice to ignore CC's warnings.
    • For the sake of consistency and clarity:
      • the 'Free scale parameter' option of the ICP registration dialog and the 'fixed scale' option of the Point-pair based alignment dialog are both renamed 'Adjust scale'
      • the 'Edit > Synchronize' tool is moved and renamed 'Tools > Registration > Match barycenters'
      • the ICP registration tool now issues the same textual report as the Point-pair based alignment tool
    • the Connected Components tool dialog now:
      • displays the octree cell size as the currently selected level
      • the components are automatically 'selected' in order to clearly identify them without random colors (the 'random colors' checkbox is not selected by default anymore)
      • the components are sorted by their size (starting from the biggest)
    • new command lines options (see http://www.danielgm.net/cc/doc/wiki/index.php5?title=CommandLine):
      • C2C_DIST: cloud to cloud distance computation
      • C2M_DIST: cloud to mesh distance computation
      • SAMPLE_MESH: to sample points on a mesh
      • FILTER_SF: to filter a cloud based on its scalar values
      • STAT_TEST: to apply the local statistical filter
      • MERGE_CLOUDS: to merge all loaded clouds
    • 'Edit > Fuse' entry renamed 'Edit > Merge'
  • Bug fixes:
    • the 'dip' value (in "dip & dip direction" computation with e.g. the plane orientation tool) was inverted from the currently accepted definition (i.e. 0° for horizontal and 90° for vertical planes)
    • blank lines or commentaries were causing an infinite loop when importing ASCII files
    • primitives (sphere, cylinder, etc.) were not correctly loaded from BIN files (CC would crash when loading them)
    • sub-meshes' bounding boxes were not updated when a transformation was applied to their parent mesh or its associated vertices
    • at loading time when an entity was both too far and too big, the (optional) applied transformation to recenter and rescale the entity was wrong.
    • a call to the 'Zoom on selected entities' tool on entities not displayed in the active window would be ignored.
    • the 'camera link' tool would sometimes make CC crash (windows were playing ping-pong ;).
    • CloudCompare can now recover from errors encountered in OBJ normals or texture coordinates (normals or textures are simply discarded)
