White water shader (Houdini)

There is a lot of discussion online about shading fluids therefore I used water simulation from "The legend of Tarzan" as inspiration.  I used Houdini`s flip particles velocity data to drive Mantra`s default shader color attribute. Also this approach is based on new Houdini 15 flip workflow. This is raw 12 fps render without foam (I`ll add foam, spray and bubbles as separated pass later)

Amount of white water and intensity is controllable therefore it is possible to have more or less shading at any point of time. Here is shaded flipbook:

and here are white water velocity particles pass:
