We introduce two fundamental advances to the NanoVDB data structure: dynamic GPU-native topological updates, and a voxel-sequential access paradigm that dramatically accelerates point-wise and stencil-based operators on sparse grids. NanoVDB's …
Solvers for grid-based discretizations of Partial Differential Equations (PDEs) are ubiquitous in computer graphics. However, efficient implementation of such solvers is contingent on specific design choices for grid data structures (especially for …
