Abstract
An image processing apparatus and method that make it possible to decode encoded data of 3D data with increased ease. A bit stream is generated which includes projection direction information including information relating to a projection direction of position information of 3D data representative of a three-dimensional structure on a two-dimensional plane and encoded data of a geometry image obtained by projecting the position information on the two-dimensional plane.
