Hi, I have a video of the "Wave Test" I created about 9 years ago at the age of 16 or 17 . No fancy shader stuff by then, each wave is a quad stretched and faded smoothly and not even texture animation involved. Position and direction are simply calculated by selecting the terrain quads which intersect the water plane and determining their slope and averaging their normals projected to the water plane. I definitely have the source somewhere, but that's still from a time where I made backups to hundreds of CDs without printing labels on them with my quad-speed cd writer . If I happen to find the source, I'll post it here. Anyway, here is a video of the demo. Skip to 00:25 to see the wave quads without rendering the water: https://docs.google.com/file/d/0B1TfEz4GUYOmSUp4b3JtR1ZPMjQ/edit# Greetings, Florian
