The laser scanning point clouds are very dense, they contain so much detail. In the past, I remember complaining about not having high density data and not having high accuracy when I create 3D models. However, in the last few years, with the advance laser scanning sensor devices, I found myself complaining about how big the point clouds are and how much detail they contain. The intensity of details and measurement accuracy became “too much” especially when the data wanted to be visualized in an informative way.
I found it a great idea to combine the simulation ideas I got from the game engines with the laser scanning points assuming them as individual particles or particle groups to animate.
Animating point clouds gave opportunity to;
- Make the details visible when they are wanted
- Make the scanning trajectories visible
- Show object detection or other process results visible in an informative way like a movie
- Show change detections not only as before/after views, but also like movies as if the event is happening slowly (points are moving from their old positions to the new positions). In this way, the changes are shown clearly to the eyes of the observer.
The video that I am sharing with the link below shows some example point cloud animations about;
- Trajectory of the laser scanner during the scanning process (See the person walking in the corridors, visiting rooms and climbing the staircases)
- The points which are acquired at different scanning positions

If you wish to apply point cloud animations in your applications, I will be very happy to discuss. Therefore, please contact me at firstname.lastname@example.org
