Catlike Coding

Part four of the Flow series adds support for transparent water. Not satisfied with regular transparency, we include underwater fog and fake refraction effects. It is a bit awkward doing this in a surface shader, but the techniques used can also be applied to custom rendering pipelines. I have teste

In this part of the Flow series we forget about textures and instead create waves by displacing mesh vertices. We begin with a simple sine wave, then move on to a Gerstner wave, give it a direction, and combine multiple of them. Waves (Catlikecoding)

Part two of the flow series moves on to directional patterns. The idea is simple: rotate the water pattern to align with the flow direction. However, getting a good result when flow isn't uniform requires a bit more work... Directional Flow (Catlikecoding)
