1. A computer-implemented method of data compression, the method comprising:

  • identifying a dataset representing one or more images, wherein the dataset comprises at least one of point cloud data or points from a 3D mesh;

    determining a set of voxels for the dataset;

    determining a set of 2D slices from the set of voxels of the dataset;

    determining a set of segments for each slice in the set of 2D slices;

    wherein a segment comprises one or more connected pixels in a 2D slice;

    compressing, by one or more processors, each segment in the set of segments to form a compressed set of 2D slices; and

    applying entropy coding to the compressed set of 2D slices.
