openvdb-7.1.0-bp156.3.4

- update to 7.1.0:
  - Added a novel parallel sparse FastSweeping class that outperforms our
    existing techniques for computing signed distance fields in addition to
    supporting velocity extension.
  - Added tools::fogToSdf which converts a scalar (fog) volume into a signed
    distance field.
  - Added tools::sdfToSdf which re-normalizes a signed distance field;
  - Added tools::fogToExt which extends an arbitrary field (e.g. velocity)
    off the iso-surface of a scalar (fog) volume.
  - Added tools::sdfToExt which extends an arbitrary field (e.g. velocity)
    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.
  - Added tools::fogToSdfAndExt which re-normalizes a signed distance and
    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.
  - Added Grid::isTreeUnique() to tell if the tree is shared with another
    grid.
  - Added PointDataLeafNode::stealAttributeSet() and
    AttributeSet::removeAttribute() for releasing ownership of attribute
    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
    array is known to be in-core and non-uniform.
  - Add support for default value metadata when creating AttributeArrays or
    appending to an AttributeSet.
  - Added new group inspection methods to the AttributeSet::Descriptor.
  - Introduced a StringMetaCache class for convenient string attribute
    metadata lookup and performed some minor optimizations.
  - Removed redundant floor in points::floatingPointToFixedPoint.
  - Add gitignore to repository root.
  - Removed some logic for compilers older than Visual Studio 2019.
  - Add a new Houdini ABI test binary.
  - Fixed an indexing typo in tools::Filter. [Contributed by Yuanming Hu]
  - Removed redundant null pointer checks. [Contributed by Kuba Roth]
  - Added support for vdb_view on Windows. Requires GLEW.
  - Removed support for GLFW 2.
  - vdb_view now uses OPENVDB_LOG_FATAL when catching exceptions.
  - vdb_view, vdb_print and vdb_render now use std::terminate() when catching
    an unknown exception.
  - Removed Boost::thread as a dependency of vdb_view in favour of
    std::thread.
  - Removed usage of boost/integer.hpp and boost/math/constants/constants.hpp,
    the latter in favour of new openvdb math constants for pi
  - Removed usage of boost/mpl/*.hpp methods in favour of new template
    meta-programming methods on the openvdb::TypeList struct. This now
    supports get, front, back, contains, index, unique, popback, popfront
    and range removal of types.
  - Changed the tree::NodeChain implementation to use an openvdb::TypeList
    rather than a boost::mpl::vector and updated all usage of tree::NodeChain
    accordingly.
    Bug fixes:
  - Fixed a bug where grids with no active values might return true when the
    method evalActiveVoxelBoundingBox is called. The correct behavior is to
    only return true if the grid contains any active values.
  - Fixed a sign propagation bug in tools::traceExteriorBoundaries() used by
    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]
  - Fixed a rotation order bug in tools::local_util::decompose()
    that caused it to fail to decompose some matrices.
  - Fixed a bug where math::Quat::inverse() was not marked as const.
    [Contributed by Michael Tao]
  - Fixed a bug in the unit test for util::CpuTimer on Windows by using a
    more accurate sleep implementation.

- add 8G memory constraint

- add tools subpackage for the command line programs

- 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
    [Contributed by David Aguilar]
  - Added SIMD intrinsics to a few common NodeMask methods.

    Bug fixes:
  - Fixed a bug in FindJemalloc.cmake where paths were not being handled
    correctly.
  - Fixed a Windows build issue in openvdb_render.
  - Fixed a non deterministic threading bug in tools::meshToVolume() during
    polygon voxelization which could result in different distance values.
    ABI changes:
  - OpFactory destructor is now virtual as of ABI=7
  - Added new virtual methods for copying const grids and replacing
    the metadata and/or the transform - GridBase::copyGridReplacingMetadata,
    GridBase::copyGridReplacingTransform and
    GridBase::copyGridReplacingMetadataAndTransform.
  - AttributeArray copy constructor is now thread-safe.
    API changes:
  - VolumeToMesh::pointList() and VolumeToMesh::polygonPoolList() now return
    a std::unique_ptr instead of a boost::scoped_array.
  - AttributeArray::copyUncompressed() is now deprecated.
    Python:
  - Removed the requirement of CMake 3.14 for NumPy usage.
  - Added support for Boost versions 1.65 and later when building
    the Python module with NumPy support through CMake.
  - Improved CMake Python3 support.
  - 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.
  - Added io::DelayedLoadMetadata, which stores mask offsets and compression
    sizes on write to accelerate delayed load reading.
    Improvements:
  - LeafNode::modifyValue() and LeafNode::modifyValueAndActiveState()
    now modify voxel values in place for improved performance.
  - Added math::isInfinite() and math::isNan() to resolve Visual Studio
    compatibility issues with integer types.
  - Made minor performance improvements to moving and filtering VDB points.
  - Improved performance related to a mutex contention when appending
    multiple AttributeArrays in parallel through various point operations.
  - Significantly improved the performance of createLevelSetSphere()
    using threading.
  - Improved directory and file path lookups of some CMake commands in
    the root CMakeLists.txt
    [Reported by Daniel Elliott]
  - Improved CMake support for GLFW versions 3.1 and later.
  - FindOpenVDB.cmake now correctly propagates CXX version requirements.
  - Added CMake support for linking against Jemalloc and TBB malloc
    and enabled Jemalloc by default for Linux and non-Maya builds
    and TBB malloc for all other builds.
  - Added a USE_COLORED_OUTPUT option to CMake to display compiler output
    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]
  - Partially reverted tools::ClosestSurfacePoint's distance calculations
    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.
  - CMake now correctly sets rpaths for the unit test binary.
  - 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.
  - Removed the TableT template argument from util::PagedArray.
    The table type is now hardcoded to std::deque.
  - The minimum supported version of GLFW is now 3.1.
    Python:
  - CMake now always produces a .so for the Python module on Unix
    and Linux platforms.
  - Fixed a compile-time error when building the Python module for Python 3.

    Houdini:
  - OpenVDB SOPs are now displayed in an ASWF sub-menu of the VDB tab menu.
  - Added API documentation and examples.
  - Added openvdb_houdini::GEOvdbApply(), which invokes a functor
    on a VDB primitive if the resolved grid type is a member of
    a given type list.
  - Fixed a regression in the Fill SOP that caused it to modify VDBs
    in the input detail.
  - The Combine SOP no longer crashes in Copy B mode when the destination
    is not a VDB.
  - Added a houdini_utils::OpFactory::addSpareData() method
    and addOperatorSpareData() and getOperatorSpareData() functions
    to manage spare data associated with operator types.
  - Added an opsparedata HScript command and hou.NodeType.spareData()
    and hou.NodeType.spareDataDict() methods to retrieve spare data
    associated with operator types.
  - Added a pythonrc.py startup script to set the tab menu visibility
    of nodes and their native Houdini equivalents, based on an
    OPENVDB_OPHIDE_POLICY environment variable.
  - Added a houdini_utils::OpFactory::setInvisible() method to hide nodes
    from tab menus.
  - Added an OpenVDBOpFactory::setNativeName() method to pair OpenVDB nodes
    with their native Houdini equivalents.
  - Added a houdini_utils::OpPolicy::getTabSubMenuPath() method to allow
    OpPolicy subclasses to provide their own tab sub-menu path.
  - OpenVDB nodes now override OP_Operator::getVersion() to return
    a version string of the form "vdb6.2.0 houdini18.0.222".
- Clean up spec file, remove superfluous parameterization

- Replace cmake(TBB) BuildRequires with equivalent tbb-devel, the
  latter is also available on Leap 15.x.

- Trim bias and metadata redundancies from description.
- Then openSUSE %ix86 platforms are not guaranteed to have SSE.
