Methods and equipment for encoding / decoding attributes of orthogonal projected 3D models

Abstract

At least one related solution proposes a method for encoding / decoding the attributes of orthogonally projected 3D models and intermediate 3D models, wherein, information indicates whether at least a first attribute array of the 2D models obtained by encoding the attributes of at least one of the aforementioned orthogonally projected 3D models according to the first attribute encoding mode and at least a second attribute array of the 2D models in the image obtained by encoding the attributes of at least one intermediate 3D model, Are they stored as separate images or not?
