Dear CloudCompare enthusiasts,

A new version has been released

You'll find it here: 32 bits - http://www danielgm net/cc/release/CloudCompare_bin_32bits_v2 4_12_16_2012 zip 64 bits - http://www danielgm net/cc/release/CloudCompare_bin_64bits_v2 4_12_16_2012 zip

And for the new features of this just-before-the-end-of-the-world version: - Introducing a new alignment/registration method: "Align (point pairs picking)" * aligns clouds by interactively picking 'equivalent' points in both clouds (3 pairs at least) * replaces the old "Align (auto)" research tool in the main toolbar (same icon) * more information on the wiki: http://www danielgm net/cc/doc/wiki/index php5?title=Alignment_and_Registration - Perspective mode and lights activation state are now automatically saved and restored (on the creation of a new 3D view or when CC restarts) - Overlay dialogs (manual segmentation and transformation, point picking, etc ) don't prevent CC from being closed anymore - 'Height grid generation' tool now gives more choice for the management of empty cells + all types of output (cloud, ASCII grid file, image) behave the same way - On-screen message display mechanism upgraded - Meshes without normals are now displayed with the 'diffuse front' material color (this allows one to change the default color of blank meshes) - New function: "Add constant SF" ("Edit > Scalar Fields" menu) * simple way to add new scalar fields (with a constant unique value) * very useful in conjunction with "SF Arithmetic" (to add, subtract, multiply or divide another SF by a constant) - SF Arithmetic ("Edit > Scalar Fields > Arithmetic") has a new icon (a calculator, instead of the 'diff' text with a colorbar) - PLY files associated with a texture file (comment with 'TextureFile' keyword - generated by PhotoScan for instance) are now supported - LAS import filter improved: * 'time' and 'return number' fields are now supported (i e imported as scalar fields) * color coding (8 bits or 16 bits) is automatically detected (see associated bug below) * importer is more clever (fields with a unique value are automatically ignored - in case you really need them, they can be created afterwards with the "Add constant SF" method - see above) - ASCII export filter: * adaptive precision when writing point coordinates (typically if the cloud has been shifted at loading time due to too large coordinates) * if the file extension is 'PTS', color components will be written after the scalar field value(s) so as to be readable by Autocad

• Bug fixes:
  • color from LAS point clouds were badly imported/exported (treated as 8 bits integers instead of 16 bits!)
  • 'Height grid generation' tool was generating badly shaped scalar fields that wouldn't be correctly saved in BIN files (corrupted files)
  • the plane primitive generated by the 'plane orientation' tool was not automatically added to DB tree
  • per-triangle normals are removed with 'Edit > Normals > Clear'
  • the mesh sampling method was not sampling normals in specific cases
  • custom light materials were wrongly set (in practical, custom light wasn't working at all!)
  • a bug in the display mechanism of meshes with textures (coordinates) could make CC crash randomly
  • segmenting a cloud with labels would make CC crash (for the moment labels are simply removed we need to be more clever!)

You'll also find the new ccViewer versions here: 32 bits - http://www danielgm net/cc/release/ccViewer_v1 21_32bits_12_16_2012 zip 64 bits - http://www danielgm net/cc/release/ccViewer_v1 21_64bits_12_16_2012 zip

Many thanks to: * Ken Mankoff (http://kenmankoff com) for the OS X portage (almost all bugs are solved ;) * Eugene Liscio (http://ai2-3d com/) for the great introductory video (http://youtu be/MQiD4HjhpAU) * Vehiclemetrics (http://vehiclemetrics com/) for the translation of the V2 1 documentation in english!

Enjoy,
