Abstract
The various embodiments of the invention relates to a method and a technical equipment for video compression. The method comprises processing volumetric image data comprising a plurality of points; defining a hemisphere () around a surface () normal at each point in the volumetric image; partitioning each of the defined hemispheres spatially into a predefined number of angles (); determining a representative radiance value for each angle of the predefined number of angles () of a defined hemisphere (); generating a matrix () for a point storing the determined representative radiance values; and encoding the generated matrix () for the point for video compression.
