Abstract: A method of generating point cloud predictor includes: obtaining an encoding unit, wherein the encoding unit is generated from a current three-dimensional (3D) image, obtaining a current 3D block in the current 3D image according to the encoding unit, obtaining a reference 3D block in a reference 3D image according to the current 3D block, wherein the reference 3D image is associated with the current 3D image, obtaining a reference two-dimensional (2D) unit in a reference 2D image according to the reference 3D block, wherein the reference 2D image is generated from the reference 3D image, and generating and outputting a predictor according to a variation degree between the encoding unit and the reference 2D unit.
