Methods and systems for three-dimensional model sharing

Abstract

Examples of the disclosure describe systems and methods for decomposing and sharing 3D models. In an example method, a first version of a virtual three-dimensional model is displayed via a display of a wearable head device. A request is made to a host device for data associated with a second version of the virtual three-dimensional model, wherein the second version of the virtual three-dimensional model comprises a constituent part. It is determined whether the first version of the virtual three-dimensional model comprises the constituent part. In accordance with a determination that the first version of the virtual three-dimensional model does not comprise the constituent part, a request is made to the host device for data associated with the constituent part. The second version of the virtual three-dimensional model is displayed, via the display of the wearable head device. In accordance with a determination that the first version of the virtual three-dimensional model comprises the constituent part, a request is not made to the host device for data associated with the constituent part.

 in accordance with a determination that the client computing system is in communication with the host computing system, sending, to the client computing system, a library comprising the constituent parts, the library corresponding to the virtual three-dimensional model; 
 receiving a constituent part request from the client computing system; and 
 sending one or more of the constituent parts that correspond to the constituent part request to the client computing system, 
 wherein the client computing system is configured to compose a view of the virtual three-dimensional model based on the one or more of the constituent parts.

         9 . A system comprising:
 one or more processors configured to execute a method comprising:
 receiving a library of constituent parts from a host computing system, the library of constituent parts comprising constituent parts corresponding to a virtual three-dimensional model, wherein the constituent parts comprise mesh data, texture data, or a combination thereof; 
 determining one or more parts to be included in a constituent part request based on a comparison of the library of the constituent parts and a client library of constituent parts; 
 sending the constituent part request to the host computing system; 
 receiving one or more of the constituent parts that correspond to the constituent part request from the host computing system; and 
 composing a view of the virtual three-dimensional model based on the received one or more of the constituent parts.

         14 . The system of  claim 9 , the wherein determining the one or more parts to be included in the constituent part request is further based on a version number associated with the one or more parts. 
     
     
         15 . The system of  claim 9 , the method further comprising:
 sending a connection request to the host computing system; and   connecting to the host computing system in accordance with receiving an indication of an acceptance of the connection request from the host computing system.
