Here is a list of all files with brief descriptions:

Archive.h |

DenseSparseTools.h |
Diagnostics.h | Various diagnostic tools to identify potential issues with for example narrow-band level sets or fog volumes
Exceptions.h |
File.h |
Filter.h | Filtering of VDB volumes. Note that only the values in the grid are changed, not its topology! All operations can optionally be masked with another grid that acts as an alpha-mask
FiniteDifference.h |
Formats.h | Utility routines to output nicely-formatted numeric values
Grid.h |
GridDescriptor.h |
GridOperators.h | Applies an operator on an input grid to produce an output grid with the same topology but potentially different value type

InternalNode.h | Internal table nodes for OpenVDB trees
Interpolation.h |
io.h |
Iterator.h |
LeafManager.h | A LeafManager manages a linear array of pointers to a given tree's leaf nodes, as well as optional auxiliary buffers (one or more per leaf) that can be swapped with the leaf nodes' voxel data buffers
LeafNode.h |
LeafNodeBool.h |
LeafNodeMask.h |
LegacyFrustum.h |
LevelSetAdvect.h | Hyperbolic advection of narrow-band level sets
LevelSetFilter.h | Performs various types of level set deformations with interface tracking. These unrestricted deformations include surface smoothing (e.g., Laplacian flow), filtering (e.g., mean value) and morphological operations (e.g., morphological opening). All these operations can optionally be masked with another grid that acts as an alpha-mask
LevelSetFracture.h | Divide volumes represented by level set grids into multiple, disjoint pieces by intersecting them with one or more "cutter" volumes, also represented by level sets
LevelSetMeasure.h |
LevelSetMorph.h | Shape morphology of level sets. Morphing from a source narrow-band level sets to a target narrow-band level set
LevelSetPlatonic.h | Generate a narrow-band level sets of the five platonic solids
LevelSetRebuild.h |
LevelSetSphere.h | Generate a narrow-band level set of sphere
LevelSetTracker.h | Performs multi-threaded interface tracking of narrow band level sets. This is the building-block for most level set computations that involve dynamic topology, e.g. advection
LevelSetUtil.h | Miscellaneous utility methods that operate primarily or exclusively on level set grids
logging.h |
Maps.h |
MapsUtil.h |
Mat.h |
Mat3.h |
Mat4.h |
Math.h | General-purpose arithmetic and comparison routines, most of which accept arbitrary value types (or at least arbitrary numeric value types)
MeshToVolume.h | Convert polygonal meshes that consist of quads and/or triangles into signed or unsigned distance field volumes
Metadata.h |
metadata/Metadata.h |
MetaMap.h |

ParticleAtlas.h | Space-partitioning acceleration structure for particles, points with radius. Partitions particle indices into voxels to accelerate range and nearest neighbor searches
ParticlesToLevelSet.h | This tool converts particles (with position, radius and velocity) into a signed distance field encoded as a narrow band level set. Optionally, arbitrary attributes on the particles can be transferred resulting in an additional attribute grid with the same topology as the level set grid
Platform.h |
PlatformConfig.h |
PointAdvect.h | Class PointAdvect advects points (with position) in a static velocity field
PointIndexGrid.h | Space-partitioning acceleration structure for points. Partitions the points into voxels to accelerate range and nearest neighbor searches
PointPartitioner.h | Spatially partitions points using a parallel radix-based sorting algorithm
PointScatter.h | We offer three different algorithms (each in its own class) for scattering of point in active voxels:
PointsToMask.h | This tool produces a grid where every voxel that contains a point is active. It employes thread-local storage for best performance
PoissonSolver.h | Solve Poisson's equation ∇2x = b for x, where b is a vector comprising the values of all of the active voxels in a grid
Proximity.h |
