Abstract: Techniques for generation of compressed representations for appearance of fiber-based digital assets are described that support computationally efficient and high fidelity rendering of digital assets that include fiber primitives under a variety of lighting conditions and view directions. A processing device, for instance, receives a digital asset that includes fiber primitives to be included in a three-dimensional digital scene. The processing device generates a compressed representation of the digital asset that maintains a geometry of the digital asset and includes a precomputed light transport. The processing device then inserts the compressed representation into the digital scene, such as at a location relative to one or more light sources. The content processing system applies one or more lighting effects to the compressed representation based on the precomputed light transport and the location relative to the one or more light sources.

Abstract: Techniques for generation of compressed representations for digital assets are described that support computationally efficient and high fidelity rendering of digital assets with a variety of geometries under arbitrary lighting conditions and view directions. A processing device, for instance, receives a digital asset defined by a three-dimensional geometry to be included in a digital scene. The processing device generates a compressed representation of the digital asset that maintains a geometry of the digital asset and includes a precomputed light transport. The processing device then deploys the compressed representation into the digital scene, such as at a location relative to one or more digital scene elements. The content processing system renders the digital asset by applying one or more lighting effects to the compressed representation based on the precomputed light transport and the location relative to the one or more digital scene elements.

Abstract: A scene reconstruction system renders images of a scene with high-quality geometry and appearance and supports view synthesis, relighting, and scene editing. Given a set of input images of a scene, the scene reconstruction system trains a network to learn a volume representation of the scene that includes separate geometry and reflectance parameters. Using the volume representation, the scene reconstruction system can render images of the scene under arbitrary viewing (view synthesis) and lighting (relighting) locations. Additionally, the scene reconstruction system can render images that change the reflectance of objects in the scene (scene editing).
