FIELD: data storage.
SUBSTANCE: invention relates to computing technology for compression and storage of three-dimensional data. The effect is achieved due to a computer-implemented method for compression and storage of three-dimensional data, containing the following stages. Three-dimensional data is received by a computing apparatus. The received three-dimensional data is pre-processed by being converted into a truncated function of the distance on a voxel grid. The array of the truncated function of the distance is then compressed using the tensor train (TT) decomposition or the Tucker decomposition. The obtained compressed three-dimensional data is stored.
EFFECT: compression of large three-dimensional data with minimal quality loss.
