Fluid Simulation 3D - Water

I make Water http://exey.ru/blog/home/fluid-simulation-pv3d-and-away3d
Math not mine, i get it from http://yamasv.blog92.fc2.com/blog-entry-85.html 
I read  Rick Parent "Computer Animation", he describe to ways animate liquid:
1. Geometry deformation
2. Normal vectors perturbation

For Geometry need many CPU resources(because many faces).
It's possible to make fluid animation on PV3D with "normal vectors perturbation"?
