This year the Technical Oscar goes to … 3D FLUIDS

That is what it looks like, when you see the list of winners of the category Technical Achievement Awards: it includes all major studios fluid dynamics R&D teams and first in line, the Spaniards of NextLimit creators of the 1st commercial application to compute fluid dynamics:

To Víctor González, Ignacio Vargas and Angel Tena for the creation of the RealFlow software application.
RealFlow was the first widely adopted, commercially available, easy-to-use system for the simulation of realistic liquids in motion picture visual effects.

To Jonathan Cohen, Dr. Jerry Tessendorf, Dr. Jeroen Molemaker and Michael Kowalski for the development of the system of fluid dynamics tools at Rhythm & Hues.
This system allows artists to create realistic animation of liquids and gases, using novel simulation techniques for accuracy and speed, as well as a unique scripting language for working with volumetric data.

To Duncan Brinsmead, Jos Stam, Julia Pakalns and Martin Werner for the design and implementation of the Maya Fluid Effects system.
This system is used to create simulations of gaseous phenomena integrated into the widely available Maya tool suite, using an unconditionally stable semi-Lagrangian solver.

To Stephan Trojansky, Thomas Ganshorn and Oliver Pilarski for the development of the Flowline fluid effects system.
Flowline is a flexible system that incorporates highly parallel computation, allowing rapid iteration and resulting in detailed, realistic fluid effects.

To Dr. Doug Roble, Nafees Bin Zafar and Ryo Sakaguchi for the development of the fluid simulation system at Digital Domain.
This influential and flexible production-proven system incorporates innovative algorithms and refined adaptations of published methods to achieve large-scale water effects.

To Nick Rasmussen, Ron Fedkiw and Frank Losasso Petterson for the development of the Industrial Light & Magic (ILM) fluid simulation system.
This production-proven simulation system achieves large-scale water effects within ILM’s Zeno framework. It includes integrating particle level sets, parallel computation, and tools that enable the artistic direction of the results.

Congratulations to all of them.
*BTW, there are other awarded in this category, but are awards related to film stock, camera mechanics, makeup and other topics not related to 3D.
