Open Point Clouds

File > Open Point Cloud(s)

NUBIGON can render unlimited volumes of point cloud data in real-time. NUBIGON currently supports LAS, XYZ, TXT, PTS, E57, and FARO SCENE project files (*.lsproj).

To open point clouds, select File > Open Point Cloud(s) and choose point cloud files.

TIP: Once a point cloud has been opened for the first time, an octree (*.oct) will appear in the octrees folder of the current project. From now on, we recommend opening the generated octree to avoid computation and loading times.
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 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.
