Light propagation for mixed polygonal and volumetric data

C. Zhang, D. Xue, R. Crawfis
2005 International 2005 Computer Graphics  
Some applications require scenes mixing polygonal and volumetric objects and shadows make the scenes more realistic.  ...  The shadow and soft shadow algorithm applies to all combinations of volumes and polygons, without any restriction on the geometric positioning and overlap of the volumes and polygons.  ...  ACKNOWLEDGMENTS We would like to thank the NSF Career Award (#9876022) for support to this project, and thank S.  ...

Volume synthesis [chapter]

Arie E. Kaufman
1996 Lecture Notes in Computer Science  
Volume visualization is a method of extracting meaningful information from volumetric data using interactive graphics and imaging.  ...  When volumetric data are visualized using surface rendering, a dimension of information is essentially lost.  ...  Fig. 1 is courtesy of Hughes Aircraft Co. The scene has been voxelized using voxelization algorithms, a voxel-based modeler, and a photo-mapper developed at SUNY Stony Brook.  ...

GI-cube

Frank Dachille, Arie Kaufman
2000 Proceedings of the ACM SIGGRAPH/EUROGRAPHICS workshop on Graphics hardware - HWWS '00  
We present a hardware architecture, GI-Cube, designed to accelerate volume rendering, empower volumetric global illumination, and enable a host of ray-based volumetric processing.  ...  The algorithm reorders ray processing based on a partitioning of the volume. A cache enables efficient processing of coherent rays within a hardware pipeline.  ...  The authors wish to thank Justine Dachille, Manjushree Nulkar, Klaus Mueller, Ingmar Bitter, and Kevin Kreeger for their assistance, reviews, and discussion.  ...

Block-NeRF: Scalable Large Scene Neural View Synthesis [article]

Matthew Tancik, Vincent Casser, Xinchen Yan, Sabeek Pradhan, Ben Mildenhall, Pratul P. Srinivasan, Jonathan T. Barron, Henrik Kretzschmar
2022 arXiv   pre-print
We build a grid of Block-NeRFs from 2.8 million images to create the largest neural scene representation to date, capable of rendering an entire neighborhood of San Francisco.  ...  This decomposition decouples rendering time from scene size, enables rendering to scale to arbitrarily large environments, and allows per-block updates of the environment.  ...  Methods for rendering small baseline view interpolation often use feed-forward networks to learn a mapping directly from input images to an output volume [15, 76] , while methods such as Neural Volumes  ...
