OpenVDB is an open source C++ library comprising a novel hierarchical data structure and a large suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It was developed by DreamWorks Animation for use in volumetric applications typically encountered in feature film production.

This GitHub repository hosts the trunk of the OpenVDB development. This implies that it is the newest public version with the latest features and bug fixes. However, it also means that it has not undergone a lot of testing and is generally less stable than the production releases.

OpenVDB is released under the Mozilla Public License Version 2.0, which is a free, open source software license developed and maintained by the Mozilla Foundation.

The trademarks of any contributor to this project may not be used in association with the project without the contributor's express permission.

OpenVDB welcomes contributions to the OpenVDB project. Please refer to the contribution guidelines for details on how to make a contribution.

The following provides basic installation examples for the core OpenVDB library. Other components, such as the python module, OpenVDB AX, NanoVDB and various executables, may require additional dependencies. See the build documentation for help with installations.

# Linux
# @note If your distribution does not have required versions, consider using
#   apt pinning. See the dependency documentation for more details.
apt-get install -y libboost-iostreams-dev
apt-get install -y libtbb-dev
apt-get install -y libblosc-dev

# MacOS
# @note We are using homebrew in this example to install requried dependencies
#  https://brew.sh/
brew install boost
brew install tbb
brew install c-blosc

git clone [email protected]:AcademySoftwareFoundation/openvdb.git
cd openvdb
mkdir build
cd build
cmake ..
make -j4 && make install

Note that the following commands have only been tested for 64bit systems/libraries. It is recommended to set the VCPKG_DEFAULT_TRIPLET environment variable to x64-windows to use 64-bit libraries by default. You will also require Visual Studio (for the MSVC C++ runtime and compiler toolchains), CMake and optionally vcpkg for the installation of OpenVDB's dependencies.

vcpkg install zlib:x64-windows
vcpkg install blosc:x64-windows
vcpkg install tbb:x64-windows
vcpkg install boost-iostreams:x64-windows
vcpkg install boost-any:x64-windows
vcpkg install boost-algorithm:x64-windows
vcpkg install boost-interprocess:x64-windows

git clone [email protected]:AcademySoftwareFoundation/openvdb.git
cd openvdb
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=<PATH_TO_VCPKG>\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -A x64 ..
cmake --build . --parallel 4 --config Release --target install

OpenVDB AX depends on the core OpenVDB library. NanoVDB can be built with and without OpenVDB support. Note that NanoVDB has its own build instructions, see the NanoVDB build documentation for details.

The following variables can be passed to the cmake configure command. There are more optional VDB components, see the build documentation for a complete list.
