libotbv

Library for reading/writing .otbv files.

OTBV is a file format for compressed binary volumes.
See formal specifications at eceannmor.com/OTBV_specification.html.

To load a given file, use otbv::load. The volume is automatically decompressed and reshaped.

using volume = std::vector<std::vector<std::vector<bool>>>;

std::string filename = "test_volume.otbv";
volume 3d_volume_data = otbv::load(filename);

To save a 3d volume to a file, use otbv::save. The metadata about the volume is stored within the same file.

using volume = std::vector<std::vector<std::vector<bool>>>;

std::string filename = "test_volume.otbv";
volume data = create_3d_volume();
otbv::save(filename, data);

If you are using flattened volumes, you can pass a 1d data vector and the desired resolution. The volume will be automatically reshaped.

std::string filename = "test_volume.otbv";
std::vector<bool> data = create_flattened_3d_volume();
std::tuple<int, int, int> resolution = {32, 32, 64};
otbv::save(filename, data, resolution);
