Point cloud - getting started


I want to understand how can i work with point cloud generated by lidar scans or kinect. I am interested in manipulation of points, adding color, movement etc to individual points. But I dont know how to start even thinking about it. Also is there a repository of open source point cloud?

thanks in advance :slight_smile:

You should probably familiarize yourself with ofMesh. Introductions to ofMesh can be found here.

the Kinect example in the CV examples folder that comes with the standard oF install is a good place to start or the point cloud example in the examples/3D/ folder.

i made a short tutorial video here;

walking through a variation of the Kinect example and talking about what happens when using Depth Sensors. See also the excellent tutorials from Dan Shiffman - although in processing the principles are the same… https://www.youtube.com/watch?v=QmVNgdapJJM
