Dear
CloudCompare
enthusiasts,
A
new version has been released. You'll
find it here:
- Windows
- Mac OS X:
- Linux:
- Sources:
Many thanks to all our supporters
who made donations on pledgie!
A new release
before X-mas, with lots of new features:
- CloudCompare now uses the GDAL library (Geospatial Data
Abstraction Library - http://www.gdal.org/):
- CC can now load dozens of standard 2D1/2 raster
formats (Arc Grid, GeoTiff, etc.).
- See the full list here: http://www.gdal.org/formats_list.html
- Rasters are imported as clouds (X,Y plane) with
height values (Z), RGB colors and/or other bands as scalar fields
- While you can't save clouds directly as a
raster, the 'Height Grid
generation' tool now lets you export any cloud to
a geotiff file (once rasterized) - see below
- 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
- The 'Height grid generation' tool has been enhanced:
- resampling mode: when selecting the 'min' or 'max height'
projections, the user can now choose to 'resample' the original
cloud instead of generating a regularly sampled cloud using
the grid cell's centers (i.e. the tool will select one existing point
per cell)
- 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 (instead of 32 bits by default) 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)
- you'll have to compile CloudCompare yourself
however ;)
- 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 method: 'File
> Close all'
- to remove all loaded entities
- 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
- see documentation here: http://www.danielgm.net/cc/doc/wiki/index.php?title=PluginSRA
(work in progress)
- Other enhancements:
- qPoissonRecon plugin is now based
on the latest version of the PoissonRecon
library (5.5)
- see http://www.cs.jhu.edu/~misha/Code/PoissonRecon/Version5.5/
for more insight on the new version of this algorithm
- please
note that the fully parallel version (all available cores) is only
enabled on the 32 bits version for now
- new parameters dialog
- input
cloud colors can now be mapped on the resulting mesh (quick
& dirty approach: simply assign to each mesh vertex the color
of the nearest input point)
- 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 tool will now
automatically remove the timetsamp (between square brackets)
- Cloud-to-cloud distances with 'local models'
- 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
- see 'Tools
> Fit > 2D Polygon' to create a facet
- 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)
- "Graphical
Transformation" tool
- pause button added to allow rotating/panning
the 3D view
- new keyboard shortcuts:
- space
bar = pause/unpause
- return
key = apply transformation (close the tool)
- escape
key = cancel transformation (close the tool)
- "Graphical
Segmentation" tool
- new keyboard shortcuts:
- 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:
- Max coordinate absolute value lowered
(100.000 instead of 1.000.000) in order
to avoid accuracy loss and display issues.
- note
that 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
- "Connected Components" tool:
- the dialog now displays the size of the octree
cell as the currently selected level
- components are automatically 'selected' in order to
clearly identify
them without random colors (the 'random colors' checkbox is not
selected by default anymore)
- components are sorted by their size (starting from the
biggest)
- New command lines options (see http://www.danielgm.net/cc/doc/wiki/index.php?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'
- 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
- CloudCompare can now recover from
errors encountered in OBJ normals or texture coordinates (normals or
textures are
simply discarded)
You'll
also find the new ccViewer versions here:
- Windows
- Linux and Mac OS:
- same as of CloudCompare (see above)
And
last but not least, you can make donations to the project via
'Pledgie':
Enjoy,
