Fly over the trajectory of mobile mapping point clouds

Hi,

In mobile mapping data, usually, there is a trajectory file that shows the sensor locations during data collection. I want to make an animation by flying over this trajectory and through the data again virtually. By using the GPS_Time attribute we can sort these points. Therefore, all viewpoints can be created automatically with the location of points and orientation to the next point. I wonder if we can add this functionality to the animation plug-in to use the trajectory for creating the viewpoints.
Thank you for making point cloud processing easy.

Best regards,
Heidar

Well, that would be a good feature indeed, but not that easy to implement. I'll add it to the TODO list.

what you could do is use a game engine.

Unreal or Unity.

Unreal I believe supports point clouds with native plugin, I've not used.

i use Unity. There is a 90€ plugin that can stream "infine" .las datasets. Here an example with a mobile mapping dataset.

Here i'm moving camera manually but I'm sure you could build an spline with tyour gps points and move camera along.
