A Physically Based Approach to Virtual Character Deformations
James Cameron's "Avatar" required the principal digital characters to be photo-realistic, full-screen, and almost fully naked in hundreds of shots. To accomplish this task, Weta Digital developed a robust character-simulation toolset that delivered the required level of realism.
Rendering "Avatar": Spherical Harmonics in Production
Application of spherical harmonics in a production rendering environment for accelerated final-frame rendering of complex scenes and materials.
PantaRay: Directional Occlusion for Fast Cinematic Lighting of Massive Scenes
NVIDIA Research and Weta Digital Ltd. present the results of a joint research collaboration. The talk describes the architecture of a novel system for precomputation of ray-traced sparse, directional occlusion caches used as a primary lighting technology during the making of "Avatar".
