Now for some real waves. A couple of years ago, Prof. Chin Wu and his student Justin Wanek developed the Automated Trinocular Stereo Imaging System (ATSIS) for making 4D ocean wave measurements with three video cameras. They have produced a 5 sec video of actual wave surface that 's the world's first and still the only 4-dimensional (x,y,z,t) wave measurement available. Here's the video in Youtube:
Take a closer look, this is the wave measurement as wave measurement should!
