3D LUT

3D LUT, stands for 3D LookUp Table. In film industry, it is used to match video monitor, or projector to the final film print. A 3D LUT is defined as a 3D Lattice deformer, which deforms 3D RGB color cube. Often 17x17x17 cubes are used as 3D LUTs. Most of the time RGB 10bit/component log images are used as the input for 3D LUTs. An interpolation engine is needed for calculating the values, which are between vertices, defined by the 3D LUT cube. Current products utilize trilinear interpolation for calculating these values.
