Open point cloud(s) FAQ

Point cloud characteristics & types

  • Do you support point cloud classifications?
    Yes, since version v620.

  • Do you support unstructured, structured, or unified point clouds?
    You can open all three types of point clouds in NUBIGON as long as they are in a supported file format.

Octree Generation

  • Do I have to generate an octree every time I want to view the dataset?
    No. Once you have generated the octree, you can instantly open datasets of any size.

  • How can I speed up the octree generation process?
    Please follow our tips.

  • Do I have enough disk space to open point clouds?
    Generating an octree temporarily creates auxiliary files. Please review our tips.

  • How does NUBIGON handle large coordinates?
    It is a common issue that GPUs produce artifacts when working with large coordinates. Therefore, stick with the default Offset type Origin when generating an octree.
     


Third-party-related topics

  • When I open my point cloud, I see unusual patterns in the data. How can that be?  
    This is caused by opening a point cloud with large coordinates in its original coordinates (zero offset vector). To fix this, re-generate the octree with the default Offset type option Origin.

    The patterns can also be caused by exporting point clouds from third-party software with a low precision setting. To fix this, re-export the point cloud with a higher precision (i.e., more decimals).
