- Update to version 9.0.0
* This version introduces ABI changes relative to older major
releases, so to preserve ABI compatibility it might be
necessary to define the macro OPENVDB_ABI_VERSION_NUMBER=N,
where, for example, N is 7 for Houdini 18.5 and 8 for Houdini
19.0.
* Official release of NanoVDB, which for the first time offers
GPU support for static sparse volumes in OpenVDB. See the
documentation for details.
* Faster build times from support for explicit template
instantiation, which is enabled by default for most of the
tools.
* Added support for OpenEXR 3. This is contributed by Cary
Phillips.
* Added transient data to the RootNode, InternalNode, and
LeafNode.
New features:
* NanoVDB, which for the first time offers GPU support for static
sparse volumes in OpenVDB.
Improvements:
* Added tools::countActiveLeafVoxels(),
tools::countInactiveVoxels(), tools::countInactiveLeafVoxels()
and tools::activeTiles() to perform multi-threaded counting.
The Tree methods now use these implementations.
* Moved from the deprecated TBB task scheduler to TBB arenas.
Various methods now respect the TBB arena state they were
invoked from.
* Introduced a new thread/Threading.h header to consolidate calls
to third-party threading methods.
* Minor performance improvements to dilation calls in fast
sweeping algorithms.
* Added hsvtogrb() and rgbtohsv() AX helper functions for
converting hue, saturation and value inputs to RGB values and
vice-versa.
* PointDataGrid conversion can now be performed using 32-bit
float arrays.
* Improved support for size_t grid types on systems where size_t
is a unique type. [Contributed by Brecht Van Lommel]
* Add support for dilation in one direction and extending a field
in one direction in fast sweeping algorithms.
* Added PNG support to vdb_render which can be enabled with
during CMake with -DUSE_PNG=ON.
* Explicit template instantiation has been enabled by default for
most of the tools. This pre-compiles template instantiations
into the core library to reduce the time spent compiling code
in downstream libraries or applications.
* Added a python binding for OpenVDB AX which allows you to
invoke accelerated AX code from the python module.
Bug Fixes:
* Fixed a bug where ax::run() would crash if it could not parse a
single statement.
ABI changes:
* Added transient data to the RootNode, InternalNode, and
LeafNode.
API changes:
* DynamicNodeManager can now set one grain size for threading
across leaf nodes and another for threading across non-leaf
nodes.
* StringGrid and StringTrees are deprecated.
* The NullInterrupter is now a virtual base class to help reduce
compile-time instantiation cost.
Houdini:
* Fix crash in VDB Combine in Copy B mode if the second input has
more VDBs than the first.
* VDB Vector Merge SOP is now VDB Vector From Scalar SOP to
distinguish it from the VDB Merge SOP. It keeps the same
internal name so this is merely a label change.
* Add option to pass in OPENVDB_DSO_NAMES to CMake to configure
which Houdini DSOs are compiled.
* VDB Activate SOP now has an option for the expansion pattern to
use for dilation.
* The label for Voxels to Expand is now Expand Voxels to match
Houdini.
* Fix bug to allow VDB LOD SOPs to be chained together.
* SOP Extrapolate supports dilation in one direction and
extending a field in one (domain) direction.
* The default OpenVDB ABI is now 8 for Houdini versions > 18.5.
* VDB Visualize Tree SOP is now multi-threaded and provides
slicing and color remapping.
* A new HoudiniInterrupter has been added that derives from the
NullInterrupter and the Interrupter is now deprecated. All the
SOPs have been updated to use the new HoudiniInterrupter.
* Add a sanitizer in SOP OpenVDB Extrapolate when expanding a
narrow-band level-set with a dilation value of 0, which will
result in no operation.
Build:
* Added support for TBB 2021.
* Enabled the OPENVDB_FUTURE_DEPRECATION variable by default to
warn on upcoming deprecations.
* Introduced a OPENVDB_DOXYGEN_INTERNAL CMake variable which is
ON by default and removes the majority of internal namespaces
from the generated doxygen.
* Improved the doxygen deprecation listings, folder layouts and
fixes issues when using later versions of doxygen.
* Build fixes for MinGW on Windows. [Contributed by Brecht
Sanders]
* Added support for OpenEXR 3. [Contributed by Cary Phillips]
* Added an OPENVDB_NAMESPACE_SUFFIX CMake string option which
provides the ability to customise the VDB namespace.
* The Python Module now appends the base directory defined by
Python_SITELIB to the default install path (typically
dist-packages or site-packages). [Contributed by Ignacio Vizzo]
* As of this release, VFX Reference Platform 2019 is no longer
supported. CMake now issues deprecation warnings for 2020 VFX
Reference Platform version dependencies.
* Build fixes for OpenVDB AX with C++17 and greater.
* Bumped the new blosc version future minimum to 1.17.0.
* OpenEXR is now optional for vdb_render. It can be enabled with
-DUSE_EXR=ON.
- Renenable vdb_render without OpenEXR
- Update constraints and limit memory for parallel build jobs
