Abstract

An embodiment of a graphics apparatus may include a processor, memory communicatively coupled to the processor, and a collaboration engine communicatively coupled to the processor to identify a shared graphics component between two or more users in an environment, and share the shared graphics components with the two or more users in the environment. Embodiments of the collaboration engine may include one or more of a centralized sharer, a depth sharer, a shared preprocessor, a multi-port graphics subsystem, and a decode sharer. Other embodiments are disclosed and claimed.

First claim

What is claimed is:

1. An apparatus comprising:
a memory to store a shared scene; and
logic communicatively coupled to the memory, wherein the logic is implemented at least partly in one or more of configurable logic or fixed-functionality logic hardware, the logic communicatively coupled to the memory to:
identify an overlapped region of the shared scene between a first view region of a first user and a second view region of a second user;
decode the overlapped region once to generate a decoded overlapped region; and
share the decoded overlapped region, which was decoded once, with both the first user and the second user.

2. The apparatus of claim 1 , wherein the shared scene is a 360 frame.

3. The apparatus of claim 1 , wherein the logic communicatively coupled to the memory is to:
determine the overlapped region based on a first position of the first user, a first orientation of the first user, a second position of the second user and a second orientation of the second user.

4. The apparatus of claim 1 , wherein the logic communicatively coupled to the memory is to:
decode only a portion of the shared scene that is to be viewed by one or more of the first user or the second user to avoid a decode of another portion of the shared scene that is to be unviewed.

5. The apparatus of claim 1 , wherein the logic communicatively coupled to the memory is to:
broadcast the decoded overlapped region to the first and second users.

6. The apparatus of claim 1 , wherein the logic communicatively coupled to the memory is to:
execute a first decode operation to decode a first region of the shared scene for the first user based on a first position of the first user and a first orientation of the first user, wherein the first region is to include the overlapped region;
execute a second decode operation to decode a second region of the shared scene based on a second position of the second user and a second orientation of the second user, wherein the second region is to be free of the overlapped region;
cause the decoded first region to be provided to the first user; and
cause the decoded second region and the decoded overlapped region to be provided to the second user.

7. A computing system comprising:
a graphics processor;
a central processing unit; and
a memory including a set of instructions, which when executed by one or more of the graphics processor or the central processing unit, cause the computing system to:
identify an overlapped region of a shared scene between a first view region of a first user and a second view region of a second user;
decode the overlapped region once to generate a decoded overlapped region; and
share the decoded overlapped region, which was decoded once, with both the first user and the second user.

8. The system of claim 7 , wherein the shared scene is a 360 frame.

9. The system of claim 7 , wherein the set of instructions, which when executed by the one or more of the graphics processor or the central processing unit, cause the computing system to:
determine the overlapped region based on a first position of the first user, a first orientation of the first user, a second position of the second user and a second orientation of the second user.

10. The system of claim 7 , wherein the set of instructions, which when executed by the one or more of the graphics processor or the central processing unit, cause the computing system to:
decode only a portion of the shared scene that is to be viewed by one or more of the first user or the second user to avoid a decode of another portion of the shared scene that is to be unviewed.

11. The system of claim 7 , wherein the set of instructions, which when executed by the one or more of the graphics processor or the central processing unit, cause the computing system to:
broadcast the decoded overlapped region to the first and second users.

12. The system of claim 7 , wherein the set of instructions, which when executed by the one or more of the graphics processor or the central processing unit, cause the computing system to:
execute a first decode operation to decode a first region of the shared scene for the first user based on a first position of the first user and a first orientation of the first user, wherein the first region is to include the overlapped region;
execute a second decode operation to decode a second region of the shared scene based on a second position of the second user and a second orientation of the second user, wherein the second region is to be free of the overlapped region;
cause the decoded first region to be provided to the first user; and
cause the decoded second region and the decoded overlapped region to be provided to the second user.

13. At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a computing device, cause the computing device to:
identify an overlapped region of a shared scene between a first view region of a first user and a second view region of a second user;
decode the overlapped region once to generate a decoded overlapped region; and
share the decoded overlapped region, which was decoded once, with both the first user and the second user.

14. The at least one non-transitory computer readable storage medium of claim 13 , wherein the shared scene is a 360 frame.

15. The at least one non-transitory computer readable storage medium of claim 13 , wherein the instructions, when executed, cause the computing device to:
determine the overlapped region based on a first position of the first user, a first orientation of the first user, a second position of the second user and a second orientation of the second user.

16. The at least one non-transitory computer readable storage medium of claim 13 , wherein the instructions, when executed, cause the computing device to:
decode only a portion of the shared scene that is to be viewed by one or more of the first user or the second user to avoid a decode of another portion of the shared scene that is to be unviewed.

17. The at least one non-transitory computer readable storage medium of claim 13 , wherein the instructions, when executed, cause the computing device to:
broadcast the decoded overlapped region to the first and second users.

18. The at least one non-transitory computer readable storage medium of claim 13 , wherein the instructions, when executed, cause the computing device to:
execute a first decode operation to decode a first region of the shared scene for the first user based on a first position of the first user and a first orientation of the first user, wherein the first region is to include the overlapped region;
execute a second decode operation to decode a second region of the shared scene based on a second position of the second user and a second orientation of the second user, wherein the second region is to be free of the overlapped region;
cause the decoded first region to be provided to the first user; and
cause the decoded second region and the decoded overlapped region to be provided to the second user.

19. A method comprising:
identifying an overlapped region of a shared scene between a first view region of a first user and a second view region of a second user;
decoding the overlapped region once to generate a decoded overlapped region; and
sharing the decoded overlapped region, which was decoded once, with both the first user and the second user.

20. The method of claim 19 , wherein the shared scene is a 360 frame.
