Converting from point cloud (fls/pts/ptx) file formats

Is anyone aware of a workflow to allow the conversion from fls, pts, or ptx files to a Sketchfab import?

These are all terrestrial scanner file formats - so imagine a building scan point cloud.

Thanks

MeshLab, CloudCompare

I'm not familiar with those formats, but it might be possible that one of them is simply an ascii file with a list of point coordinates (and color) like:

 # comment
x y z R G B
x y z R G B
...
x y x R G B

If that is the case, you can change the file extension to .asc, and we will be able to process it.

My way was to export the point cloud (.pts) and then convert with laszip & lasunzip to get to .txt (xyzrgb), then open in meshlab and save as a .ply.

I usually unified and cleaned my scans in Recap before exporting as .pts.

@SVickers cool - I've had success with LAStools in the past. You should be able to simply rename the .txt file to .asc and upload. No need to go through MeshLab for the PLY
