Hi Daniel,
Could you provide a reference for the mathematical background of this application? And if possible, can we save the unroll parameters after processing point cloud and then roll the point cloud back?
Bests.

This function is also enough for me.
I can handle after it.
Thank you.

Dear Daniel,

I am fitting cylinders to point clouds. But I wonder, is there a way to export all cylinders parameters to ascii file?

Similar to;

x,y,z, directions(x,y,z), radius.

From gui or command line?

Thanks.

Hi Daniel,

Thank you for responding but it is very strange. Now the file works normally. Is there a possibility like that? if I encounter this error again I can send the file.

Cheers.

Hi, I think you should write your scripts in the programming language. Reflecting point clouds to the plane as it is known as mirroring. First, define a plane at maximum Z height or higher than maximum height point. Then mirroring your points, it will change the valleys to the mountain and mountains...

I have a similar error. Did you get to fix it?

it is not possible in CC if you mean get RGB values to point cloud.

Dear Daniel,

I can not export las file which I uploaded correctly. when I tried to export same file as las, error prompts
"PDAL exception writers.las:Unable to convert scaled value(4064716612) to int32 for dimension Y when writing file/path/file.las"

Cheers.

Hi,

You can use PDAL pipeline as described here:

cheers.

Dear Daniel,

I have a problem with PLY (ASCII) importation and exportation with large coordinates. How can we overcome this issue? Binary is ok but I need to import PLY ASCII file from other software.


Thanks in advance.
