This is a C++20 upgrade of the polyvox library for primary use in overte, so not all things build/work.
PolyVox is the core technology which lies behind our games. It is a fast, lightweight C++ library for the storage and processing of volumetric (voxel-based) environments. It has applications in both games and medical/scientific visualisation, and is released under the terms of the zlib license <http://www.tldrlegal.com/l/ZLIB>_.
PolyVox is a relatively low-level library, and you will need experience in C++ and computer graphics/shaders to use it effectively. It is designed to be easily integrated into existing applications and is independent of your chosen graphics API.
