where, for example, N is 7 for Houdini 18.5 and 8 for Houdini
19.0.

narrow-band level-set with a dilation value of 0, which will
result in no operation.
Build:

off the iso-surface of a signed distance field.
- Added tools::fogToSdfAndExt which computes a signed distance and extends
an arbitrary field (e.g. velocity) off the iso-surface of a signed
distance field.

extends an arbitrary field (e.g. velocity) off the iso-surface of a
signed distance field.
- Added tools::dilateSdf which dilates a signed distance field.
- Added tools::maskSdf which extends an existing signed distance into a
user-defined mask.

data.
- Added AttributeSet::Descriptor::groupIndexCollision() for detecting
group index collisions when attempting to merge two Descriptors.
- Added RootNode::childCount(), InternalNode::childCount() and
LeafNode::childCount() to count the number of immediate child nodes that
exist below the current node.
Improvements:
- Added GroupWriteHandle::setUnsafe() for faster performance when the group

the latter in favour of new openvdb math constants for pi

rather than a boost::mpl::vector and updated all usage of tree::NodeChain

only return true if the grid contains any active values.

tools::meshToVolume(). This could cause values to not be propagated across
node boundaries, leading to voxels incorrectly being marked as inside the
isosurface. [Contributed by Tristan Barback]

- Version 7.0.0 - December 6, 2019
Some changes in this release (see "ABI changes" below) alter
the grid ABI so that it is incompatible with earlier versions
of the OpenVDB library, such as the ones built into Houdini
up to and including Houdini 18.0. To preserve ABI compatibility,
when compiling OpenVDB or any dependent code define the macro
OPENVDB_ABI_VERSION_NUMBER=N, where, for example, N is 5 for
Houdini 17.0 and 17.5 and 6 for Houdini 18.0.
As of this release, a C++14 compiler is required and the oldest
supported Houdini version is 17.0.
New features:
- LevelSetMeasure can now compute multiple types of curvatures (averge and total
Gaussian and mean curvature) as well as Euler characteristic and genus of
level set surfaces.
- Most stencil classes now have an intersection method that detcts the axial
directions of zero-crossings (as oppose to the existing boolean intersection test).
- The CurvatureStencil can now compute Gaussian and principal
curvatures (in addition to mean curvature).
- Added Tree::nodeCount, which counts the number and type of nodes
in a tree very efficiently.
- Added new RootNode::addChild() and InternalNode::addChild() methods to
allow the insertion of child nodes directly.
Improvements:
- The minimum ABI for OpenVDB is now always enforced through CMake
separately from other minimum dependency version variables.
- Added support for CMake 3.12 compatible Xxx_ROOT variables.
- Replaced the CMake USE_SYSTEM_LIBRARY_PATHS option with
DISABLE_CMAKE_SEARCH_PATHS and removed the hard coded list of
SYSTEM_LIBRARY_PATHS in favor of using CMake's default search procedure.
SYSTEM_LIBRARY_PATHS can still be used as a global list of paths for all
dependency searches.
- Improvements to OpenVDB's CMake module setup order in regards to CMake
policy, minimum version and project calls.
- Replaced occurrences of boost::scoped_array with std::unique_ptr.
- Added an OPENVDB_SIMD option to CMake to optionally define SSE4.2 and
AVX compiler flags, this is switched off by default.
- Made various small changes to improve Visual Studio compatiblity and
deprecate some logic for compilers older than Visual Studio 2017.
- Standardized CMake install locations using GNUInstallDirs. Importantly,
this changes the default library installation folder from lib to lib64
on some 64-bit systems, or to lib/multiarch-tuple on Debian

- The Python Module is now disabled by default in CMake.
Houdini:
- Fixed a bug in the Points Convert SOP during conversion from
Houdini geometry to OpenVDB Points, where point group information
could end up corrupted or cause a crash with non-contiguous
point offsets (mesh inputs).
- Threaded the population of point group memberships during conversion
from Houdini geometry to OpenVDB Points
- Added logic to the Rasterize Points SOP to suppress the output of
non-finite attribute values due to subnormal input densities.
- Introduced a position compression option to the Scatter SOP for VDB
Points and default to 16-bit fixed point.
- adjust to so version 7_0
- Update to Version 6.2.1 - September 30, 2019
Bug fixes:
- Fixed a crash that arose from an inadvertent ABI change of an I/O class
with the 6.2.0 release. The crash occured when attempting to write out
a point data grid using an I/O routine from a different version of
OpenVDB than the one with which the grid was authored and when
one of those OpenVDB versions was 6.2.0.
- Update to Version 6.2.0 - September 18, 2019
New features:
- Added tools::FindActiveValues, which counts the active values
in a tree that intersect a given bounding box.

and TBB malloc for all other builds.

in color.
- Added an OPENVDB_CODE_COVERAGE option to CMake.
- CMake now automatically detects and configures the CXX11 ABI requirement
for Houdini builds.
- CMake now issues deprecation warnings for 2017 VFX Reference Platform
version dependencies. In particular, C++11-only compilers are now
deprecated; OpenVDB 7.0 will require a C++14-compatible compiler.
Bug fixes:
- Replaced std::vector with std::deque as the underlying container
for util::PagedArray, to address a rare crash when reading
from multiple threads while writing from another thread.
- Fixed a bug that could cause an empty CoordBBox to report nonzero volume.
- Fixed a bug in tools::computeScalarPotential() that could produce
a corrupt result due to invalid memory access.
[Reported by Edwin Braun]

to their pre-OpenVDB 5.0 behavior to address a bug in the
fillWithSpheres() tool that caused generated spheres to sometimes
extend outside the target volume.

- Addressed a Valgrind warning by allocating the AttributeArray registry
using a Meyers singleton.

ABI changes:
- ABI versions 3 and older are now deprecated, and support for them will be
removed in a future release. Until then, define the macro
OPENVDB_USE_DEPRECATED_ABI (or set the CMake OPENVDB_USE_DEPRECATED_ABI
option to ON) to suppress deprecation messages when compiling OpenVDB or
dependent code.
API changes:
- Changed points::RandomLeafFilter::LeafMap from a std::map to
a std::unordered_map.

from tab menus.
- Added an OpenVDBOpFactory::setNativeName() method to pair OpenVDB nodes
