APPLICATION SHARING

1 . A method comprising:

at a first device having a first processor, executing a first application via the first processor;

determining a first state of the first application;

generating a first scenegraph corresponding to the first state of the first application;

at a second device having a second processor, executing a second application via the second processor

generating a second scenegraph corresponding to a first state of the second application; and

at a host device, receiving 3D data, wherein the 3D data comprises data associated with the first scenegraph and data associated with the second scenegraph; and

generating a centralized scenegraph based on the 3D data.

2 . The method of claim 1 , wherein the first application is installed on the first device and the first application is not installed on the second device.

3 . The method of claim 1 , wherein generating the centralized scenegraph comprises traversing the centralized scenegraph by a renderer of the host device.

4 . The method of claim 3 , wherein the renderer is configured to apply one or more of lighting effects, shadow effects, shaders, particle effects, and physical effects to the centralized scenegraph.

5 . The method of claim 1 , further comprising writing information corresponding to the 3D data to a memory.

6 . The method of claim 1 , further comprising:

presenting the centralized scenegraph to the first device, and

in response to receiving the third scenegraph at the first device, rendering a view corresponding to the third scenegraph on a display of the first device.

7 . The method of claim 6 , further comprising receiving, from the first device, a request to present the centralized scenegraph, wherein:

the request to present the centralized scenegraph is generated in response to an interaction between the first device and a trigger, and

presenting the first scenegraph to the first device is performed in response to receiving the request.

8 . The method of claim 7 , wherein the trigger comprises location information associated with the first device or a QR code.

9 . The method of claim 7 , wherein the request comprises an identification of the first application.

10 . The method of claim 1 , further comprising:

at the host device, receiving input from the first device;

determining, based on the input, a second state of the first application, the second state different than the first state;

generating a third scene graph corresponding to the second state, the third scenegraph different than the first scenegraph;

at the host device, receiving 3D data comprising data associated with the third scenegraph; and

updating the centralized scenegraph based on the 3D data.

11 . The method of claim 10 , further comprising presenting the updated centralized scenegraph to the second device, wherein the second device is configured to, in response to receiving the updated centralized scenegraph, render to a display of the second device a view corresponding to the updated centralized scenegraph without executing the first application.

12 . The method of claim 10 , wherein the 3D data comprises data representative of a change between the third scenegraph and the first scenegraph.

13 . The method of claim 1 , wherein the 3D data is received via a multi-threading technique.

14 . The method of claim 1 , wherein the first device comprises a wearable head device.

15 . The method of claim 1 , wherein the host device comprises a server.

16 . A non-transitory machine readable medium storing instructions, which, when executed by a host device having one or more processors, cause the host device to perform a method comprising:

receiving 3D data, wherein the 3D data comprises data associated with a first scenegraph and data associated with a second scenegraph; and

generating a centralized scenegraph based on the 3D data,

wherein:

the first scenegraph corresponds to a first state of a first application executed at a first processor of a first device; and

the second scenegraph corresponds to a first state of a second application executed at a second processor of a second device.

17 . The non-transitory machine readable medium of claim 16 , wherein the method further comprises presenting the centralized scenegraph to the first device and the second device.

18 . The non-transitory machine readable medium of claim 16 , wherein generating the centralized scenegraph comprises traversing the centralized scenegraph by a renderer of the host device.

19 . The non-transitory machine readable medium of claim 16 , wherein the method further comprises:

receiving 3D data comprising data associated with a third scenegraph, wherein the third scenegraph corresponds to a second state of the first application, the second state different than the first state; and

updating the centralized scenegraph based on the 3D data.

20 . The non-transitory machine readable medium of claim 19 , wherein the 3D data comprises data representative of a change between the third scenegraph and the first scenegraph.
