voxel-io is a C 17, MIT-licensed library for reading and writing various voxel formats. It also comes with various useful C utilities for math, bit-manipulation, logging, asserts and more.

voxel-io is lightweight in the sense that STL-includes are heavily optimized and only used where absolutely necessary. No third party dependencies exist, only single-header libraries (lodepng, miniz-cpp) were used.

All sources can be found in src/. Headers can be found in include. src/format contains the readers/writers for various voxel formats.

src/3rd_party contains third-party libraries. These are implementation details and using them through voxel-io is not safe. They might be changed by voxel-io or they might be removed entirely in the future.

To build using CMake:

mkdir build
cd build
cmake .. # -DCMAKE_BUILD_TYPE=DEBUG for debug builds, otherwise release is default
make # -j NUMBER_OF_THREADS

voxel-io should build in about 1-2 seconds with multithreading.
