Sony patents 3D file format that reduces processing load
Sony describes a method for compressing 3D data by separating the basic shape, surface details, and movement instructions into different data streams. This structure allows computers to process the 3D model more efficiently by only loading the level of detail needed for the current view.
In the filing’s own words
The present disclosure relates to information processing apparatus and method that enable an increase in processing load related to reconstruction of 3D data including displacement vectors to be suppressed. A base mesh and attributes are encoded, displacement vectors are encoded for each of layers of levels of detail, a content file is generated, encoded data of the base mesh is stored in a base-mesh track of the content file, encoded data of the attributes is stored in an attribute track of the content file, encoded data of the displacement vectors for each of the layers is stored in mutually different displacement tracks of the content file, and association information for associating the displacement tracks with the layers is stored in the content file. The present disclosure can be applied to, for example, an information processing apparatus or an information processing method.
What exactly they claim (claim 1)
1. An information processing apparatus, comprising: an encoding unit that encodes a base mesh and attributes and encodes displacement vectors for each of layers of levels of detail; and a content file generation unit that generates a content file, stores encoded data of the base mesh in a base-mesh track of the content file, stores encoded data of the attributes in an attribute track of the content file, stores encoded data of the displacement vectors for each of the layers in mutually different displacement tracks of the content file, and stores first association information for associating the displacement tracks with the layers in the content file, wherein the base mesh is a mesh that is generated by decimating vertices from an original mesh as an encoding target, the original mesh being constituted by vertices and connections representing a three-dimensional structure of an object, the mesh being lower in the level of detail than the original mesh, the attributes include textures that are applied to surfaces of the original mesh, and the displacement vectors are vector information indicating displacement of vertices obtained by subdividing the base mesh.
