"It just seemed incredible to me that something like this would ever happen," Veach says when reached recently at a ski resort north of
"This is for work that is 15 years old but is essentially having an impact now. For me, it just seems like this is an incredible bonus. I've been doing nothing in graphics for 15 years and then the next thing you know the Academy is calling me up and wants to talk to me about my thesis work."
Veach's 1997 PhD thesis into the way light behaves has allowed filmmakers to produce more accurate computer graphics, while later research into deep shadowing technology helped create the furry creatures in "
That's where he figured out how best to simulate the way light bounces around an environment. Movie studios took note and used it to produce more realistic computer graphics, which rely in large part on the way light is depicted.
"Your eye really picks up when the lighting isn't correct," notes Veach, who now lives near
He says the trick is in accurately simulating indirect illumination _ light that bounces and reflects from one object to another, such as under a table or along the edges of a super hero's cape.
Years ago, such tweaks would have been handled manually or required many expensive computers, says Veach, who received a scientific and engineering award plaque for the research.
"It's only just recently that computers have gotten fast enough that rather than having artists spend all their time just trying to make things look realistic, a lot of studios have now decided that it's cheap enough (to) simulate the actual physics," he says, adding this gives artists more time to focus on the artistic side of their work.

"To make it look realistic you need to have very accurate shadows," he says of the work, which earned the duo technical achievement award certificates from the academy.
"When you look at fur or hair, all of the hair is casting shadows on each other. And I remember this creature, Sullivan, had four million hairs all casting shadows on each other so the existing methods they had at that time for dealing with shadows were just too expensive to use on a creature that complicated."
Their work was later widely adopted as the foundation of early deep compositing, a method of smoothly combining three-dimensional layered elements such as spaceships, explosions and live action into one image.
Although sci-tech winners receive certificates or plaques instead of the more well-known Oscar statuettes, Veach says the bash is still considered a tremendous honour in the sci-tech community.
"This is the 'sciences' part of the
"But still, it's exciting to get any sort of recognition from the academy. And it is a great honour."
Other Canadian winners this year included a group of Montrealers who made "bullet-time" possible in "The Matrix," two
