Visualising 3D point clouds in PointBox

With the proliferation of 3D point clouds generated by terrestrial and bathymetric lidar, multibeam sonar and photogrammetry methods, the visualising of these 3D point clouds online is becoming more important for end-users, and easier.

Here we have used PointBox, which uses Potree - open-source WebGL based point cloud renderer - to host 3D point clouds of several Great Barrier Reef islands and the Yongala wreck, all done by photogrammetry:

Note, these are best viewed with the browser Chrome, and allow the screen time to refresh after moving the model, as there are millions of points to be visualised.
