Great game engine With GREAT WATER!

I just found this on the web. It's a completely free game engine called nGENE

This is about the same water implementation my engine's using, I just didn't implement any reflections yet (and I use a quickly put together heightmap and normal map for the waves)

There's an article on gamedev on how to implement it, but they assume you have a deferred renderer, it would be possible in a forward renderer but it'd be a lot more costly and just a lot harder to implement in general

Crap

It is possible to set up a deferred renderer in irrlicht you know

It takes some getting used to, but it's really awesome to work with once you get the hang of it

I might do that after I learn C++ (after I learn Java and make some mini games)

Good water is not that hard, and people have been doing that for years, so you can find example code on near every technique.

BTW: you might want to check out the water scene node on this forum too.

While making good looking water doesn't have to be hard, making actual realistic water is probably one of the hardest things possible
To this day not a single affordable water implementation has been found which even gets close to matching realistic water behavior

Things like decent refraction and reflection, realistic caustics, light scattering, soft water-shore transitions, realistic water flow, etc. are insanely hard to get right
To get some of these implemented correctly you'd have to look at equations related to fluid dynamics, which is a topic they're still doing heavy research on

That'd be the fact on just about anything, no? Modeling realistic behavior of anything is either not possible or not possible in realtime. Realtime graphics are cheats upon cheats, and the only goal is "does it look good".

Jep. Modeling realistic water is possible. ILM has proven it

The problem here is real-time
