i rendered small resolution water by rendering it like an animated terrain with spheremapped texture and it looks ok.

but it is obviously very inefficient specially for largscale water like a large landscape. how can this be achieved as i've seen it done in many games?

thanx in advance.

Wow! Big question!

These days the most commonly used approach for large bodies is a set of DUDV and DOT3 textures, large low poly meshes, and some nice shaders...

The Virtual Terrain project is a good place to start.

Check out the pages on bodies of water. There is a whole section with articles, papers and even links to Open Source examples.
