v2.13.2

Improvements:

• substantial improvement of the cloud merge operation (thanks to Thomas Watson)

• symbolic link files (or shortcut or alias) should now be properly handled

• command line:

  • increase the timestamp resolution of the registration matrix filename and best fit plane information filename so as to avoid overwriting them if generated too quickly
  • new sub-option -NO_LABEL after -O
    • prevents any label from being loaded/created automatically (in case text columns are present in the input file)
    • for ASCCI files only

• Korean translation updated (thanks to Yun-Ho Chung)

• The Animation plugin now uses ffmpeg 6.1

• The 'Normals computation' dialog should remember whether normals 'orientation' should be resolved or not

• PCD files can now be loaded or saved with local characters. PCD files will also be saved as compressed files by default.

Bug fixes:

• The LAS dialog could be be wrongly initialized with a point format of 0 in some cases (with FWF data).
  • In command line this could result in missing waveforms when saving. Thanks to Paul Leroy for the fix ;)
• The Rasterize tool was not letting the user use '0' as the max edge length parameter for the Delaunay-based raster interpolation mode (forcing the user to set a high value to keep all triangles)
• The scale value in the bottom right corner of the 3D view (orthographic mode) was wrong if the screen height was larger than the width
• After the -FEATURE command line command was run, the automatically exported filename of clouds was containing some duplicated contents
• The Poisson Reconstruction progress dialog 'cancel' button was ineffective (the process cannot be canceled). It is now hidden.
• Per-vertex colors were never saved in a Maya (MA) file
• Loading a corrupted STL filter could result in a corrupted mesh or a crash
• The Compass plugin had some minor but numerous memory leaks
• The torus primitive mesh topology was broken
• LAS files: the synthetic flag could be mistakenly set at save time if some non-zero classification values were present
• The envelope/contour extraction routine of the Cross Section tool could fail or crash in some cases
• Canupo: some scalar fields were not properly removed/cleaned in some cases

v2.13.1

v2.13.1 (Kharkiv) - (03/20/2024)

Improvements:
- the Facets plugin will now retain the Global Shift information when extracting facets, and the 'Global center' will
also be exported when exporting facets info to CSV or SHP files
- the Compass plugin will now warn the user if a wrong entity is picked
- the 'Edit > Tools > Apply transformation' dialog accuracy has been improved (so as to properly handle small rotation angles)
- It is now possible to save clouds (points and normals) as an OBJ file
- the 'Tools > Distances > Cloud/Mesh distances' tool will now use a smarter algorithm to avoid edge cases
when determining the sign of the distance.
- the dialog has a new 'robust' option (enabled by default) to control whether this new algorithm should be used,
or if the old algorithm should be used.
- the ICP tool dialog also has a 'robust' option (Research tab) to control this behavior when using C2M distances
- new command line option -NON_ROBUST to force the old behavior for both the C2M distances computation and the ICP
tools (see below)
- Command line options
- New suboption for the -C2M_DIST command line option:
- -NON_ROBUST to disable the robust signed C2M distances computation algorithm (old behavior)
- New suboptions for the -ICP command line option:
- -USE_C2M_DIST to force the computation of Cloud/Mesh distances (only if the reference entity is a mesh)
- -NON_ROBUST to disable the robust signed C2M distances computation algorithm (old behavior)
- -NORMAL_MATCH {OPTION} to specify the normals matching mode (no normal matching is used by default).
{OPTION} can be OPPOSITE, SAME_SIDE or DOUBLE_SIDED
- The 3DFin plugin version has been bumped to 0.3.3

Bug fixes:
- CSF: the multi-threading strategy could cause artefacts in the cloth simulation, leading to suboptimal results
- CSF: the acceleration component was wrongly multiplied twice by the square time increment, requiring much more
iterations for the algorithm to converge
- 3DMASC: when using a test cloud, the process was automatically terminated as if the user had clicked on the
'cancel' button
- The DotPorduct (DP) file I/O filter was not able to load files with non latin characters. It was also wrongly
reporting its ability to export files while it is no longer the case.
- Upgrading the DotProduct SDK to version 5.2 to avoid crashes when loading some DP files
- The -EXTRACT_CC command line option could overwrite the automatically saved component clouds if multiple clouds were
originating from the same file. Now the component filenames will contain the cloud name and index in the file to
make sure they are unique.
- The Global Shift information was not always saved when exporting to the PCD format
- When refusing to change the Global Shift & Scale information after applying a transformation, the Global Shift & Scale
information could be reset
- When changing values in the Apply Transformation tool, a chain of events/updates could lead to a strange behavior
of the dialog

v2.13.alpha.230227

New 2.13.alpha version (02/27/2023)

v2.12.4 (Kyiv)

v2.12.4 (Kyiv) - (14/07/2022)

• Bug fixes:
  • CloudCompare 2.12.X (X<4) could miss some triangles when computing the Cloud-to-Mesh distances (resulting in slightly overestimated distances)
  • CloudCompare would still apply the Global Shift even though it was rejected by the user (which is a bad idea ;). But the entity
    Global Shift would then be (0, 0, 0), resulting in the loss of the original coordinate system.
  • the scale in the lower-right part of the 3D view could have the wrong length (if the height of the window is larger than its width)
  • FBX: CloudCompare couldn't properly load the materials (textures) of meshes with quads
  • the Compass plugin was exporting large coordinates with a too small precision
  • the command line could ignore the input global shift (set with -GLOBAL_SHIFT) if it was not sufficient
    to make the points coordinates small enough. This was not consistent with the previous behavior.
  • the segmentation tool in Perspective mode could keep points behind the camera/viewpoint

v2.12.3 (Kyiv)

Bug fixes:

• CloudCompare would still apply the Global Shift even though it was rejected by the user (which is a bad idea ;). But the entity Global Shift would then be (0, 0, 0), resulting in the loss of the original coordinate system.
• the scale in the lower-right part of the 3D view could have the wrong length (if the height of the window is larger than its width)

v2.12.2

v2.12.2 (Kyiv) - (23/05/2022)

• Improvements:

  • CSF plugin:
    • 'Cloth resolution' and 'Classification threshold' input precision has been increased from 0.1 to 0.001

• Bug fixes:

  • The LAS PDAL filter could fail to save additional fields with space characters in their name on some architectures (Linux mostly).
    The filter will now automatically replace space characters (and equal characters) by specific sub-strings to be able to restore
    the original name when loading the LAS file later.
  • The LAS 1.3 or 1.4 filter was applying the Global Shift to the points even if the original 'LAS offset' was different. But it was declaring in the LAS file header that it has used the original LAS offset.
    This would lead to a shifted LAS file with the wrong global coordinates.
  • When double-clicking on a file with local characters in the Windows explorer, CC was not able to interpret the filename or file path correctly
  • Computing per-triangle normals (or methods requiring to update per-triangle normals such as Laplacian smoothing) could lead to a crash on some OBJ meshes

v2.12.1 (Kyiv)

• Improvements

  • ICP registration:

    • new option to prevent all rotations in the 'Research' tab ('None' option of the Rotation combo-box), to be consistent with the command line version

    • the number of grid cells is now displayed (next to the grid size)
    • the number of non-empty cells is now displayed (next to the cloud name and size)

  • Most of the progress dialogs of CloudCompare should not steal the focus anymore (when loading multiple files in the background for instance)

  • Segmentation tool:

    • the icons are now visually disabled (grayed out) while drawing a polyline. Keyboard shortcuts are still working.

• Bug fixes:

  • The '-ICP -ROT NONE' command line option was not working as expected
  • When saving in a Shapefile the polyline exported from the Interactive Segmentation tool, an invalid global bounding-box was computed and saved by CC.
  • Label markers were preventing the user from picking the points below (in the Point picking tool as well as other tools)
  • LAS filters will now automatically convert NaN values to a default value when saving fields
    (as NaN is not valid according to specifications and not accepted by most third party libaries and tools)

v2.12.0 (Kyiv)

• New tools:

  • Menu 'Edit > Cloud'

    • 'Edit > Cloud > Create single point cloud': to create a cloud with a single point (set by the user)

  • For now, allows to save the geometry of clouds and meshes (as well as normals or RGB colors,
    but not the texture, etc.) with a configurable compression ratio

• Improvements

  • New Display options:
    • option to select the application style (Windows Vista, Windows, Fusion, etc.)
    • single click picking can be disabled (can be very slow for very large point clouds)
  • Graphical Segmentation Tool (scissors):
    • the tool can now segment polylines (it will only keep segments with both vertices visible)
    • various improvements (visibility of segmented entities is forced for more clarity, etc.)
    • new option to flag the points inside the polygon with a given class value (instead of segmenting the points).
      • a 'Classification' SF will be added to the cloud if none already (otherwise the 'Classification' SF will be updated)

  • Rasterize tool
    • RGB and scalar field based layers can now be exported to standard image formats
    • improved interpolation scheme on the raster borders
    • new 'max edge length' option when interpolating grid cells, to avoid using large triangles
    • the rasterize tool grid is 'centered' on the raster (image) boundary pixels (the grid min corner coordinates

      right raster cell center). This has been made more explicit in the 'Edit grid' sub-dialog.
  • Section extraction tool

    • Can select whether to use Least Squares fitting on found shapes (some shapes take a very long time to process this step specifically Cones)
    • Can select whether to attemot to simplify shapes (torus->cone/cylinder/sphere/planes cone->cylinder/sphere/plane cylinder->sphere/plane, sphere->plane)
    • Can choose whether or not to have a random color assigned to each shape found.
    • Ability to select min and max radii for various shapes (helps prevent giant spheres and cylinders from beating out the more likely plane feature)
  • ICP registration:
    • new option to take the normals into account (if both entities have normals)
      (several matching modes are available: same side, opposite side, or double-sided)
    • new 'research' option to use signed distances when registering a cloud with a (reference) mesh
      (helpful to prevent the cloud from sinking below the mesh surface if used in conjunction of a small overlap percentage)
  • Clipping box tool:
    • former 'contours' renamed 'envelopes' for the sake of clarity
    • ability to extract the real contours of the points inside each slice (single slice mode or 'repeat' mode)

      • New option '-MAX_EDGE_LENGTH' to set a maximum edge length when interpolating values
        (to be used with the '-EMPTY_FILL INTERP')

    • the 'OCTREE_NORMALS' option has been updated:
      • MINUS_ZERO and PLUS_ZERO can now also be written MINUS_ORIGIN and PLUS_ORIGIN
      • new sub-options '-ORIENT PLUS_SENSOR_ORIGIN' and '-ORIENT MINUS_SENSOR_ORIGIN' (to use the sensor origin to orient the normals - a sensor must be associated to the cloud of course ;)
    • New sub-option for the 'ROUGH' command (Roughness):
      • '-UP_DIR X Y Z' to specify a 'up direction' to compute signed roughness values.
  • PCD:
    • CC can now load PCL files with integer xyz coordinates (16 and 32 bits) as well as double (64 bits) coordinates
    • CC can now load 'scan grids' corresponding to structured clouds (so as to compute robust normals for instance)
    • the (standard ?) 16bytes alignment...

v2.11.3 (Anoia)

Bug fix:

• when used with only 3 points (pairs), the Align tool could produce a wrong registration matrix
