Open Point Clouds

File > Open Point Cloud(s)

When opening point clouds for the first time, NUBIGON generates a highly efficient data structure (octree) and completes a series of processing tasks for better visual quality and performance. This only needs to be done once. In subsequent instances, you’ll be able to open the octree instantaneously regardless of data volume.

NUBIGON currently supports LAS, XYZ, TXT, PTS, and E57 files. To open point clouds, select File > Open Point Cloud(s) and choose point cloud files.

TIP: You can open multiple files in a single operation.

Next, you will be prompted with the following Octree Options window:

Octree Name

(optional) You can change the name of the octree file.


The dropdown menu Offset Type provides four options: Origin, User, Previous and None.

  • If your data has large coordinates, offset to the Origin to avoid display artifacts
  • Use Previous to use the offset vector of the last opened point cloud.
  • Choose User to enter an offset vector manually.
  • Select None to open with the original coordinates.
TIP: NUBIGON always preserves original coordinates for export.


Compute Normals: Select this option for enhanced visual quality and precision.

Smoothness: This parameter controls the roughness of the generated model. Higher values produce more smooth models.

Remove duplicates: If selected, duplicate points are automatically removed.

Skip colorless scan positions: If your data has scan positions that do not contain RGB information, check this box to exclude those positions from the final model.

Force 8-bit colors: In certain cases, 3rd party software packages will export LAS files with 8-bit colors instead of 16-bit (as outlined in the LAS specs), resulting in colorless octrees. In these cases, re-generate the octree by enabling this option.
