Abstract
Methods and systems for encoding and compressing 3D object data models are provided. An example method may involve receiving 3D mesh data for an object that includes geometry coordinates for a surface of the object. Additionally, material properties may be associated with the geometry coordinates. The method may also include identifying multiple portions of the mesh data based on the material properties associated with the geometry coordinates. For example, a given group of adjacent geometry coordinates having common material properties may be identified as a given portion. For at least some of the identified portions of the mesh data, the method may further include encoding information related to an identified portion of the mesh data and compressing the encoded information into a file of compressed geometric data.
