Making CG Hair More Realistic


Advertisements


- Making Realistic hair in computer animation is one of the most cumbersome job, specially because of huge rendering time,..ask CG artists at
Dreamworks, how they manage to create more furry creatures in Madagascar than in any previous computer-animated film. Now Researchers at Cornell Univercity has developed a new and much more quicker method for rendering Realistic looking CG Hair...... Text from thier site - Reproducing this visual effect in computer graphics has always been a challenge. Computers can create three-dimensional structures resembling hair, but the process of "rendering," in which the computer figures out how light will be reflected from those structures to create an image, requires complex calculations that take into account the scattering between hairs. Current methods use approximations that work well for dark hair and passably for brown, but computer-generated blondes still don't look like they're having more fun. But now Cornell researchers have developed a new and much quicker method for rendering hair that promises to make blond (and other light-colored) hair more realistic.Steve Marschner, Cornell assistant professor of computer science, developed the new method with Cornell graduate student Jonathan Moon, who will present the work at the 2006 SIGGRAPH computer graphics conference in Boston.
