Method, device, and computer-readable recording medium for compressing 3d mesh content

A device for compressing mesh content representing a 3-dimensional (3D) object,

• the mesh content including vertex information about a plurality of vertexes of the 3D object, a face command about a face formed by connecting the vertexes, and texture information about a color of the face,
• the device comprising:
• a memory,
• a communicator, and
• at least one processor,
• wherein the at least one processor is configured to:
• obtain a scale factor and generate a plurality of scaled vertexes by changing an interval between the vertexes,
• generate a mesh point cloud by padding a space between the scaled vertexes with points,
• obtain a geometry image from the mesh point cloud,
• obtain a texture image based on the texture information,
• display the scaled vertexes on an occupancy map,
• translate the face command based on at least one of the scale factor or the occupancy map, and
• generate a bitstream by compressing the geometry image, the texture image, the occupancy map, and the translated face command with a video based point cloud compression (V-PCC) encoder.
