We present a new algorithm for best-effort simplification of polygonal meshes based on principles of visual perception. Building on previous work, we use a simple model of low-level human vision to estimate the perceptibility of local simplification operations in a view-dependent Multi-Triangulation structure. Our algorithm improves on prior perceptual… (More)
We describe a multiresolution radiosity caching method that enables efficient computation of global illumination (GI) in a single pass in complex CG movie production scenes.
Figure 1: Two scenes from the CG movie 'Monsters University'. Top row: direct illumination. Bottom row: global illumination — images such as these render more than 30 times faster with radiosity caching. c Disney/Pixar. Abstract We present a multiresolution radiosity caching method that allows global illumination to be computed efficiently in a single pass… (More)
