Encoding Occupancy in Memory Location for Efficient and Compact High‐Resolution Voxel Structures

open access: yesComputer Graphics Forum, EarlyView.
We encode information about geometric structure into the pointers of a sparse voxel directed acyclic graph (SVDAG). Each pointer carries information about the structure of the node it points to. Our encoding improves ray tracing performance and reduces model size in memory.
