I’m very interested in the concept of rendering 3D water.
This is present in video games, yes, but I see it as a blockade in most 3D generation. It’s been a problem ever since 3D graphics were conceptualized; making rendered water realistic. I’ve seen only a few examples of legitimately fluid water, and here’s one such example.
The reason it’s so difficult is it required physics engines to calculate the positions of each piece and make the whole flow of the 3D water natural.
Unfortunately, liquids have so many individual points within them, that it’s nearly impossible to calculate them all.
I’m unaware of what artists dabble in this type of art, but I know it requires teams or animators and programmers to get even remotely right.
I think the processing engines we are creating now will be able to handle such types of programs, and 3D generation, in general, will improve.
