I am trying to create the effect of the water surface thickness with a vertex-fragment shader.
I am in a 3D game environment but It’s a scroll view so a “2D” view.
Here is a good tutorial of creating such effect in real 2D using fragment shader.
But this can’t be used in my case I think.
For the moment I have only a plane were I apply refraction.
And I want to apply the water thickness effect. But I don’t know how to do it.
I am not trying to create some water deformation/displacement using vertex for the moment, this is not the point.
I don’t know if it’s possible with a simple quad maybe should I use an object like this.
Here are some examples.
I don’t have any idea on how to create this effect.
Thanks a lot !
[EDIT] Added Rayman water effect to have a better reference of the effect.
