    • Refined build system
    • Fast global registration
    • Color map optimization
    • PyPi support
    • Changing Python package name: py3d -> cloudViewer

      • Tools > Registration > Move bounding-box center to origin
      • Tools > Registration > Move bounding-box min corner to origin
      • Tools > Registration > Move bounding-box max corner to origin
    • Edit > Plane > Flip: to flip the selected planes

    • Edit > Mesh > Flip triangles: to flip the triangles (vertices) in case they are defined in the wrong order
    • Tools > Distances > Cloud/Primitive Dist
      • Used to calculate distance to primitive shape (supports spheres, planes, cylinders, cones and boxes) rather than the mesh of that shape (more accurate results for spheres)
        planes are now optionally treated as bounded or unbounded.
        for cones this will not work with Snout mode cones.
    • New tool:
      • Edit > Normals > Export normals to SF(s) (or equivalently Edit > Scalar fields > Export normals to SF(s))
      • Command line argument: -NORMALS_TO_SFS (all dimensions are exported by default as 3 scalar fields)
    • Command line:
      • '-H_EXPORT_FMT' added to select format for hierarchy objects exported
      • The PCV tool can now be accessed via the command line:
      • RANSAC plugin support added, all parameters below are optional and can be added in any order, and will work on all clouds opened and already loaded when called
        • '-RANSAC' (main command)
          • EPSILON_ABSOLUTE - max distance to primitive
          • EPSILON_PERCENTAGE_OF_SCALE - max distance to primitive as a percentage of cloud scale 0.0-1.0 exclusive
          • BITMAP_EPSILON_PERCENTAGE_OF_SCALE - sampling resolution as a percentage of cloud scale 0.0-1.0 exclusive
          • BITMAP_EPSILON_ABSOLUTE - sampling resolution

          • OUTPUT_INDIVIDUAL_PRIMITIVES - output detected shapes meshes
          • OUTPUT_INDIVIDUAL_PAIRED_CLOUD_PRIMITIVE - output detected shapes clouds & meshes

      • '-NORMALS_TO_DIP': converts the loaded cloud normals to dip and dip direction (scalar fields)
      • '-NORMALS_TO_SFS': converts the loaded cloud normals to 3 scalar fields (Nx, Ny and Nz)
      • '-REMOVE_RGB': to remove RGB colors (from all loaded entities, i.e. clouds or meshes)
      • '-REMOVE_Normals': to remove normals (from all loaded entities, i.e. clouds or meshes)
      • The 1st Order Moment tool (Tools > Other > Compute geometric features) can now be accessed via
        the command line mode with option -MOMENT {kernel size}
        • Computes 1st order moment on all opened clouds and auto saved by default.
      • The Feature tools (Tools > Other > Compute geometric features) can now be accessed via
        the command line mode with option -FEATURE {type} {kernel size}
        • type is one of the following: SUM_OF_EIGENVALUES, OMNIVARIANCE, EIGENTROPY, ANISOTROPY, PLANARITY, LINEARITY, PCA1, PCA2, SURFACE_VARIATION, SPHERICITY, VERTICALITY, EIGENVALUE1, EIGENVALUE2, EIGENVALUE3.
    • 4 new default color scales:
      • Brown > Yellow
      • Yellow > Brown
      • Topo Landserf
      • High contrast

  • Improvements

    • Better support for High DPI screens (4K) on Windows
    • Both the local and global bounding-box centers are now displayed in the cloud properties (if the cloud has been shifted)
    • The PoissonRecon plugin now relies on the PoissonRecon V12 library
      • new algorithm
      • option to set the final 'resolution' instead of the octree depth
    • Align (Point-pair based registration) tool
      • can now be used with several entities (both several aligned and several reference entities)
      • option to pick the center of sphere entities as registration point(CC will ask whether to use the sphere center or not when picking a point anywhere on a sphere entity)
    • All parameters should now be properly remembered from one call to the other (during the same session)
    • The current box/slice position can now be exported (resp. imported) to (resp. from) the clipboard via the 'Advanced' menu
    • Command line tool:
      • The C2M_DIST command (Cloud-to-Mesh distances) can now be called with 2 meshes as input. In this case the first mesh vertices are used as compared cloud.
      • New suboption for the -O -GLOBAL_SHIFT option: 'FIRST'
        To use the first encountered (non null) global shift for all loaded entities (must be defined for all entities nevertheless ;)
      • The CROP command will now remove the input cloud if it's totally 'cropped out' (instead of leaving the full original cloud loaded)
      • The 'FWF_O' command (to load LAS files with associated waveform data) now properly supports the '-GLOBAL_SHIFT' option
      • No more popup will appear when loading a raster file via the command line mode in SILENT mode (raster is never loaded as a textured quad, and invalid points are always ignored and not loaded)
      • One can now use the 'auto' value for the radius value input after -OCTREE_NORMALS to automatically guess the normal computation radius
    • Graphical segmentation:
      • points are now exclusively segmented inside/outside the frustum
    • Plugins:
      • plugins may now be enabled/disabled in the plugin info window
      • to take effect, ACloudViewer must be restarted
      • all plugins are still available on the command line
    • PCD now supports loading more field types (16 bit signed and unsigned, 32 bit unsigned, 64 bit floating point)
    • OBJ files:
      • we now correctly handle faces with more than 4 vertices! (they should be properly tessellated)
      • support of escaped lines ('' at the end of the line)
      • now accepts MTL files with the 'Tf' keyword (well, CC just ignores it and doesn't complain about a wrong MTL file anymore ;)
      • enhanced progress report (thanks to https://gitlab.com/Epic_Wink)
    • M3C2:
      • the computation speed should be improved when using a small projection radius (smarter selection of the octree level)
    • LAS files:
      • the standard LAS Filter now handles the OVERLAP classification bit (for point format >= 6)
      • improved/fixed management of classification and classification flags
      • LAS offset (chosen at saving time) should be a little bit smarter:
        • CC will try to keep the previous one, or use the bounding-box min corner ONLY if the coordinates are too large
        • CC won't use the previous scale if it is too small for the current cloud
        • the 'optimal' scale is simpler (round values + the same for all dimensions)
      • The LAS 1.3/1.4 filter (Windows only) has been improved:
        • option to save any scalar field as extra bytes (and load extra bytes as scalar fields)
        • proper minor version setting
        • proper header size
        • using the latest version of LASlib with proper management of UTF8/UTF16 ('foreign') characters
    • ASCII files:
      • now allows mixed white space (spaces / tabs)
      • the ASCII load dialog option has now an option to load numerical values with a comma as digit separator ('use comma as decimal character' checkbox)
    • Unroll
      • ability to set the start and stop angles for the cone unrolling options
      • ability to unroll meshes
      • new unrolling mode: 'Straightened cone' (the previous one has been renamed 'Straightened cone (fixed radius)'). This new mode unrolls the cone as a cylinder but with a varying radius.
    • The 'Straightened cone' options are now using the real curvilinear abscissa (0 = cone apex)
    • Tools > Others > Compute geometric features
      • option to compute the 1st moment added
      • option to compute the 1st, 2nd and 3rd eigenvalues added
    • SBF files

  • Changes

    • Command line tool:
      • The -FBX_EXPORT_FMT command is now split. Use -FBX -EXPORT_FMT.
    • Plugins:
      • The I/O plugin interface has changed, so if you have your own I/O plugins, you will need to update them.
        • The interface name changed from ccIOFilterPluginInterface to ccIOPluginInterface.
        • The ccIOPluginInterface::getFilter() method was removed in favour of ccIOPluginInterface::getFilters().
        • The FileIOFilter base class now takes a struct as an argument containing all the static info about a filter - extensions, features (import/export), etc.. See FooFilter in the ExampleIOPlugin and the comments in FileIOFilter::FilterInfo.
        • The use of FileIOFilter::FilterInfo means that the following virtual functions in I/O filters are no longer virtual/required:
          • importSupported
          • exportSupported
          • getFileFilters
          • getDefaultExtension
          • canLoadExtension
      • The GL plugin interface has changed, so if you have your own GL plugins, you will need to update them.
        • The interface name changed from ccGLFilterPluginInterface to ccGLPluginInterface.
    • CC will now handle external matrices (loaded or input via the 'Edit > Apply Transformation' tool) with a 16th component different than 0
      (this 16th component will be considered as the inverse scale)
    • Attempt to improve gamepads detection/connection

  • Bug fixes:

    • repair ccPlane Entity bounding box showing bugs and normal vector showing bugs
    • LAS classification flags were not always properly extracted/saved by the standard LAS filter (depending on the point format)
    • Trace Polyline tool: when changing the OpenGL camera position while tracing a polyline AND using oversampling, strange spikes could appear
    • The Unroll dialog was not enabling all the apex coordinate fields after switching from Cylinder to Cone mode
    • The Clipping-box tool 'edit' dialog would sometimes move the box in an unexpected way when opening and closing it without making any change
    • M3C2: the 'subsampling' option was not properly restored when loading the parameters from a file (if 'SubsampleEnabled = false')
    • Orienting normals with a sensor position could lead to a crash
    • Shapefile: at export time, the SHX file (created next to the SHP file) was malformed
      • this prevented loading the file in most GIS tools
      • polylines were mistakenly exported as polygons
    • SRS (Spatial Reference System) information could be lost when loading LAS files
    • The cartesian bounding-box of exported E57 files was wrongly expressed in the file-level coordinate system (instead of the local one)
    • Data could be lost when merging two clouds with FWF data
    • When VBOs were activated with an ATI card, ACloudViewer could crash (because ATI only supports 32bit aligned VBOs :p)
    • The LAS 1.3/1.4 filter was not compressing files with a minor case 'laz' extension :(
    • The iteration stop criteria has been changed in the CSF plugin to fix a small bug
