Here is the final video of the Shower scene.
Shading, Lighting, Rendering and Water Simulation by me.
Textured head with morph targets by Sri Ram.
Some details :
Head modeled in max and sculpted,posed and textured in Mudbox
Water was simulated with glu3d gpu at 400 fps. (and it was fast at that fps to simulate)
Simulation took 2 hours (realtime) and the final rendering took 70 hours using iRay. Water meshing was done with Frost which was realtime.
