Visualization of a point cloud with 1 billion points

Visualization software written in OPENGL for point clouds having billions of points. The software runs on a standard PC and uses no more than 50 MB of RAM and doesn't allocate more than a few 100 MB on the graphics card. The screen resolution was set to 1920x1080. The software reads points directly from the hard disk drive to the GPU when needed.

The camera was moved using the mouse which is why some movements seem non-smooth, but looking at the FPS there is no drop anywhere.

Please watch in 1080p!

YouTube's compression makes the video look blurry, so a less blurry version can be found at:
