T-Octree voxel data compression library

This Tucker-Octree (T-Octree) library compresses 3-dimensional dense datasets using octree multiresolution approach with Tucker decomposition. The collected core and factor matrices are further compressed with the ZFP library.

Installation

Typical cmake installation:

```bash

mkdir build; cd build cmake .. -DCMAKEBUILDTYPE=Release -DEigen3DIR="path/to/share/eigen3/cmake" -DzfpDIR="path/to/lib/cmake/zfp" -DCMAKEINSTALLPREFIX="/vdf_compression" make install ```

After that add -Lpath/to/vdf_compression/lib to linker flags and -Ipath/to/vdf_compression/include to compiler flags for vlasiator.

Licensing

T-Octree is licensed under GPL2.0 or later (see LICENSE text).

Dependencies

T-Octree utilizes the following codes:
