Abyss

This is a screenshot the the Abyss, this is the use of cgi to create a realistic water face called Pseudopod.

As cgi established itself, it became photorealistic cgi, which is self explanatory, this played a key part in the academy award winning abyss, for visual effects. This was mainly for the water creature, that was in the film. It is very realistic, you couldnt really get any better in my opinion, and they have done a good job there, thats why they won a award.
