The Affect:

How do you create a water affect in DBP? In World of Warcraft characters can walk into water, and you can see the water move in ripples away from them.

I am speculating that this uses a ghosted matrix with animated water texture, specular on, and that the matrix has many 'verticies' that can be manipulated by a 'vertex shader' to create the ripple affect when a character walks into it.

What about spouts, waterfalls, and splashes? Probably uses some particle affects I'm guessing.

The Ripple Algorithm:

I'm speculating that the ripple affect is a function of sine inside a dampening function, and that the range of the ripple is determined by the velocity of the character.

1.) range = character velocity * ratio
2.) for dampening = 1 to range
3.) (sin(f)*range)/dampening
4.) next dampening

The Question:

How do you create your water affects?

wrong section. I know its 3d chat, but this is a shader problem. Try Evolveds Water shaders, and then once you have basic water down with that, you could try vertex manipulation, or you could do a simple sprite that appears to splash or ripple.

Evolveds Water shaders? What & where is that? Is that a code block, a plugin, what?

Thanks

Evolved's downloads come with demos.
Its not code or plugin, its an .fx file(shader).
