Abstract : We address the problem of rendering extremely complex virtualscenes with large amounts of detail. We focuson high-end off-line rendering algorithms based on path tracing thatare intensively used in the special effects and 3D animation industries.The large amounts of detail required for creating believable virtual worldsraise important efficiency problemsthat paralyze production rendering pipelines andgreatly complicate the work of 3D artists.We introduce new algorithms for prefilteringcomplex 3D assets while preserving their appearanceat all scales, in order to reduce loading times,ray intersection costs, shading costs and Monte Carlo noise,without lowering the quality of rendered frames.Our main contributions are a new hybrid LODapproach that combines the benefits ofmeshes and volumetric representationsfor prefiltering complex 3D assets,as well as a new approach for prefilteringhigh-resolution heterogeneous participatingmedia.
