chris82, I think I know which tutorial you''re talking about... why don''t you just download the sample and look at what the author did?

Also, the article was primarily about how to create waves in a height-map; the author decided to use the effect on a 2D texture (in the sample app), but you could certainly render the height-map in 3D, too.

eric,
i have the source but it is very complex!
it do very much more thing than the tutorial!
i''m not an expert in 2d (i do opengl)and i have seen that the effect was cool and pretty simple and i had will to make it but i didn''t understand how to apply the height map!
it''s not easy understand a similar thing when you don''t know much of 2d!
if you know this can you explain to me or tell me where to find a tutorial that explain not the water effect but the use of the map.
