INFORMATION PROCESSING DEVICE AND METHOD

The present disclosure relates to information processing device and method capable of suppressing reduction in encoding efficiency.At least some of internal vertices which are vertices of a mesh representing an object having a three-dimensional structure and positioned other than the boundary of a patch of a geometry are deleted, vertex connection information indicating the vertices of the mesh and connections between the vertices is generated, and the vertex connection information is encoded. Furthermore, coded data of vertex connection information indicating boundary vertices which are vertices of a mesh representing an object having a three-dimensional structure and positioned at least at the boundary of a patch of a geometry and connections between the boundary vertices is decoded, and the vertices positioned in the patch and the connections between the vertices are reconstructed using the vertex connection information obtained by decoding the coded data and a geometry image in which the patch is arranged on a two-dimensional plane. The present disclosure may be applied to, for example, an information processing apparatus, an electronic device, an information processing method, a program or the like.
