Abstract: System and methods for rendering three-dimensional (3D) object data models based on a comparison of images. A 3D object data model of an object can be characterized by parameters defining rendering features of the 3D object data model. A comparison can be made of a first rendering of the 3D object data model to one or more reference images related to the object and, based on the comparison, the parameters of the 3D object data model can be modified. Following the modification, the 3D object data model can be rendered to generate a second rendering. Based on the second rendered 3D object data model, statistical information can be obtained and based on the statistical information, the parameters of the 3D object data model can be modified again to further adjust the appearance of the second rendering of the 3D object data model.

Abstract: Methods and systems are provided for determining and transmitting applicable lighting information, applicable viewing perspective, and a 3D model for an object in response to a search query. An example method includes receiving, at a server, a search query regarding an object. A 3D model for the object is determined. The 3D model includes three-dimensional shape information about the object. The method also includes determining, based on a plurality of stored images of the object, at least one applicable light field and at least one applicable viewing perspective. A search query result is transmitted from the server. The search query result may include the 3D model, the applicable light field(s), and the applicable viewing perspective(s). A server and a non-transitory computer readable medium are also disclosed that could perform a similar method.

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.

Abstract: Methods and systems for interacting with multiple three-dimensional (3D) object data models are provided. An example method may involve providing to a display device for display a first 3D object data model and a second 3D object data model. Information associated with a modification to the first 3D object data model may be received. Based on the received information, a same change may be applied to the first 3D object data model and applied to the second 3D object data model to obtain a first modified 3D object data model and a second modified 3D object data model. According to the method, the first modified 3D object data model and the second modified 3D object data model may be provided to the display device for substantially simultaneous display.
