In NUBIGON, you can open multiple related point clouds as one or multiple octrees. Here we outline both workflows.
Option A: Open multiple point clouds as one octree
- Click File > Open Point Cloud(s), select all point clouds, and generate octree.
- You can select multiple point cloud files in the same folder and generate one octree from them.
- Once the octree is generated, you can set its display mode or toggle its visibility.
Option B: Open multiple point clouds as individual octrees
Step 1: Generate octree from the first point cloud
- In the Octree Generation Settings, verify that the Offset is set to Origin (in a new scene, it is set to Origin by default) and generate the octree of the first point cloud.
Step 2: Generate octree(s) from subsequent point clouds
- In the Octree Generation Settings, verify that the Offset is set to Reference > Last point cloud (if there is already an octree in the scene, this option will be set by default) and generate the octrees of the other point clouds.
- All octrees will be listed individually in the Object List.
- You can now configure display modes and toggle the visibility of each octree individually.
- This is particularly helpful in distinguishing different parts of a site.
- Option B will save octree generation time when working with large datasets but may deliver suboptimal visualization outcomes in areas where two octrees overlap.
