Re: Cloud Point showing up as a straight line

Yes, so you can see that the bounding box along X and Y is super small (<0.02) and super large along Z (> 420). This is once again typical from a geographical coordinate system. You can try to rescale X and Y with the 'Edit > Multiply / scale' tool (by using a factor of 100 for instance for X and Y ...

Re: Saving the vertices of the best fit plane as text file

To export to ascii, you have to use -C_EXPORT_FMT ASC (or TXT should work). This must be placed before -SAVE_CLOUDS.

And before calling -EXTRACT_VERTICES, I would remove the cloud with -POP_CLOUDS (so that only the plane remains, because it's a mesh).

Re: Animation Plugin: trajectory and viewports

Animation Trajectory: the plugin can only export a polyline for now... The other pieces of information would have to be exported as a series of 'viewport objects' I guess? As one 'viewport' object for each frame, or something like that. But that would require to modify the code of the plugin. And sa...

Re: Thin wall cloud > mesh signed distance calculation

Yes, CCCoreLib doesn't manage normals at all. So it would definitely not be easy to pass this information and use it in the existing algorithm without a lot of refactoring...

Re: Issue Comparing Diver-Derived and ROV-Derived Photogrammetry Models in CloudCompare

Generally, when this issue happens (a 'linear' cloud), this is due to the cloud being saved with a Geographic coordinate system (with angular coordinates for X and Y, and metric coordinates for Z, and a totally different scale). CloudCompare doesn't automatically convert these geographic coordinates...

Re: Deleting overlapping sections in an imported LIDAR scan

By any chance, are the coordinates of the points very large? Maybe Blender doesn't like large coordinates? (just as CloudCompare, OpenGL, etc.). In which case, before exporting the cloud to a new file, you could remove the Global shift (with 'Edit > Edit Global Shift & Scale') so as to only keep...

Re: Optimize RMS of Quadric Fit

Well, sadly not. And this tool is meant to be used on a 'surface' (cloud), not a linear one. That may be the cause of the issue?
