There's no "undo" in CloudCompare ;)

The best way to do this is either to clone your data before applying any process ... or to reload!

I'll answer to both of your questions here: - no OpenGL in CCLib, as it is only meant to apply geometry related algortihms. There's even no normal in point clouds. All the display related stuff is added by heritage in qCC_db (the "database" of qCC). This library is highly dependent on Qt h...

Hello, CCLib is not depending on any GUI system. It is meant to be used by any kind of solution (to my knowledge, it is used - appart from qCC - by two other projects - one is purely in command line, and the other one is based on Virtools). Recently, we add a dependency to Qt, but it's only for the ...

Hi, i'm not sure to understand why VTK (which is a multi-purpose library to load/process/display all kinds of 3D data) would not be compatible with OpenGL. See vtkOpenGLRenderer for instance. However that's not really the point as what Dimitri propose is not to use PCL to display entities, but only ...

I forgot something:

Once you have a scalar field, check the 'display scale' checkbox at the bottom of the cloud 'Porperties', in the 'SF Scale' section (left side of the screen). See attached example.

Hello, Color scale is only available for scalar fields (one floating point value associated to each point). The "Color ramp" tool is just a way to assign colors (R,G,B) to a cloud. Therefore, to do what you want to do: - you can indeed use the "height grid generation" tool, but b...

Ok, so it appears that it was a 'unicode' encoded text file (UTF8 exactly) while CloudCompare doesn't handle such enconding styles. It needs pure 8bit ANSI (such as what the classical Notepad tool generates). I'll try to figure out if Qt could help CloudCompare be more 'subtle'... meanwhile, don't u...

It works with my own ICM files, but please send me yours: daniel.girardeau@gmail.com (or add it as an attachment to your reply).

Oh, it may also come from your text editor. Can you still test this with the new CC version on the trunk? (or do you need an executable?)

Hello, are you trying to do this on Linux? I checked the code and I saw that the comparison between the first line in the file and what is attended (#CC_ICM_FILE) is a bit harsh (it includes also the 'carriage return' character (which is never a good idea, as it is not the same for Unix and Windows ...
