In VisionLidar, navigating in the point cloud was designed to be as intuitive as possible. Here is a list of the main functions available:
- Drag with the left mouse button: Rotate the view
- Drag with the right mouse button: Zooms the view, dragging up zooms out and dragging down zooms in.
- Drag with both left and right mouse button simultaneously: Pan the view
- Drag with the mouse scroll button: Pan the view
- Mouse scroll: Zoom in the view
- Double click with the left mouse button: Updates center point of the viewer at the double-clicked point
- Spacebar: Reset the view to show the entire indexed point cloud
Furthermore, several icons are available to help with navigating and viewing the point cloud:

| Fix vertical axis in rotation | When rotating, this option fixes the vertical axis so that the global orientation of the view is maintained. |
| Top view | Fix the view on top of the center point, rotations will only be possible around the vertical axis. Note that the view is still projected and not orthogonal. |
