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)

CGI Water pipeline

RnD on CGI water pipeline, comparing Naiad, Realflow and Houdini`s new Flip solver. Pretty decent

results for 5 million particles. bgeo cache size is around 45GB. Flip solver stores, beside others, velocity
attribute for isolating white water and spray particles.
