Hi, Do CC offer any algorithm that would allow me to mark exact center of a polyline traced on point cloud? I already had such vector from my previous project and tried to calculate normals and convert into dip/direction scale to at least check whether this tool is good at all. As I assumed, it didn...

Yup, thats it.
Thanks Daniel

Pity, but it was worth to try :)

Hi! Quick question regarding endless CC capabilities :) Is there any algorithm/workflow that would allow me to detect the lowest part of the sagging powerline? Sure, I can calculate distance to dround but this parameter is not always correlated (terrain geometry varies under the line) so I'd need to...

Hi! While doing demo of CC to some people from geodesy they pointed out issue/feature related to coordinates. According to them global coordinates sampled from LIDAR cloud are not accurate enough as they are too short. Number preceding coma is ok, but there is not enough data after the separator... ...

Thanks Daniel! It works! I need to tame it but works. BTW: when generating raster I've encountered weird thing. Z axis view looks great, X as well, but when trying to export along Y axis cloud - kind of - changes rotation, from horizontal to vertical. I know, this is how it should be, but is there a...

Hi! I am looking for a solution to export 2d tiff visualizing the powerline along its route. Obviously the line does not run on a stright path, but I need to visualize legs of a certain length (i.e. 500 meters or 1km). Is there an workflow allowing to "unroll" the cloud along the centerlin...

Sure! Will send it asap.

Thanks!

Hi Daniel! Thanks for such lightning quick response! Yup, this method works perfectly. Brilliant simplicity! The pattern remains despite few attempts. I've tried on photogrammetry and lidar datasets, it is visible on both. While prepping the data I've also tried rasterization of the ground points (t...

Hi! Since there is no straightforward way of normalizing the point cloud for further visualization in CC I decided to combine two functions: C2C algorithm for calculating height of the points above ground export data as .PLY import of PLY file but switching Z coordinates with results of C2C calculat...
