Title: THREE-DIMENSIONAL MODEL DISTRIBUTION METHOD, THREE-DIMENSIONAL MODEL RECEIVING METHOD, THREE-DIMENSIONAL MODEL DISTRIBUTION DEVICE, AND THREE-DIMENSIONAL MODEL RECEIVING DEVICE
Abstract:
Provided is a three-dimensional model distribution method comprising a step of generating a depth image from a three-dimensional model (S121) and a step of distributing the depth image and information for restoring the three-dimensional model from the depth image (S122). As an example, the three-dimensional model distribution method may further comprise a step of compressing the depth image using a two-dimensional image compression format, and this compressed depth image may be distributed in the distributing step. As an example, in the step of generating a depth image, a plurality of depth images having different viewpoints may be generated from the three-dimensional model, and in the compressing step, the plurality of depth images may be compressed using relations among the plurality of depth images.
