By Susan L. HowardPhysical Simulation Developer
Weta Digital, New Zealand
Research AssociateEarth & Space Research in Seattle, WA
The Science Behind Computer Generated
Visual Effects
Grew up in JeffersonvilleB.A. Rutgers University (Math, Physics
minor)M.S. Oregon State University (Oceanography,
Math minor)
Worked as Physical Oceanographer for 11 years
Worked in Digital Effects for 4 years as a Physical Simulation Developer.
Recently moved back to Seattle and am working again as a Physical Oceanographer.
My Background
Physical OceanographerStudies the physical properties of the ocean
Heat, saltMotion (currents)ClimateIce
I specialize in :
Polar OceanographyTidesData analysisNumerical modeling
Weta Digital is a five-time Academy Award winning visual effects facility based in Wellington, New Zealand.
Weta was formed in 1993 by Peter Jackson, Richard Taylor and Jamie Selkirk.
It later split into two specialized halves - Weta Digital (digital effects) and Weta Workshop (physical effects – props, swords, masks).
Weta Digital Employs ~900: artists, scientists, programmers

Tintin ALL Digital Effects!
What do Oceanography and FX workhave in Common? (or how did I end up at Weta!)
FLUID DYNAMICS
What do Oceanography and FX workhave in Common? (or how did I end up at Weta!)
In fluid dynamics, we have something called the EQUATIONS of MOTION.
The EQUATIONS of MOTION describe how fluid moves.
We use these equations, coded in computer models, to try to simulate a real oceans. Or, in the case of movies, to make realistic looking water!
Fluid Dynamics
In movies, we use the principles of Fluid Dynamics to model

Other types of computer modeling workHair motionCloth movementBody mechanicsFalling objects, collisions

All these effects need to follow physical laws – or they will look fake!!!!!
