Abstract

Claims (49)

1 . A computer-implemented method comprising:

generating, by at least one processor, a 3D XR user interface comprising virtual content;

determining, by the at least one processor, using 3D coordinate data of the virtual content, one or more portions of the virtual content located outside of a stereoscopic field of view of a user;

determining, by the at least one processor, a near clipping plane at a first specified distance from a head-wearable apparatus worn by the user and a far clipping plane at a second specified distance from the head-wearable apparatus;

performing, by the at least one processor, a conic projection from the near clipping plane to the far clipping plane, the conic projection having an opening angle using a start angle and an end angle of the stereoscopic field of view;

generating, by the at least one processor, a clipping mask using the conic projection;

clipping, by the at least one processor, from the XR user interface, the one or more portions of the virtual content located outside of a stereoscopic field of view of the user using the clipping mask; and

providing, by the at least one processor, the XR user interface to the user.

2 . The computer-implemented method of claim 1 , wherein clipping the portion of virtual content comprises:

generating a clipping mask based on the stereoscopic field of view of the user; and

clipping the virtual content not located within the stereoscopic field of view of the user using the clipping mask.

3 . The computer-implemented method of claim 2 , wherein the clipping mask is a clipping volume.

4 . The computer-implemented method of claim 1 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a left monoscopic field of view by clipping the virtual content from a right virtual content rendered image of the virtual content.

5 . The computer-implemented method of claim 1 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a right monoscopic field of view by clipping the virtual content from a left virtual content rendered image of the virtual content.

6 . The computer-implemented method of claim 1 , wherein clipping the portion of the virtual content comprises clipping the virtual content from a left virtual content rendered image of the virtual content and a right virtual content rendered image of the virtual content.

7 . The computer-implemented method of claim 1 , wherein the XR user interface is provided to the user using a head-wearable apparatus.

8 . A machine comprising:

at least one processor; and

at least one memory storing instructions that, when executed by the at least one processor, cause the machine to perform operations comprising:

generating a 3D XR user interface comprising virtual content;

determining using 3D coordinate data of the virtual content, one or more portions of the virtual content located outside of a stereoscopic field of view of a user;

determining a near clipping plane at a first specified distance from a head-wearable apparatus worn by the user and a far clipping plane at a second specified distance from the head-wearable apparatus;

performing a conic projection from the near clipping plane to the far clipping plane the conic projection having an opening angle using a start angle and an end angle of the stereoscopic field of view;

generating a clipping mask using the conic projection;

clipping from the XR user interface, the one or more portions of the virtual content located outside of a stereoscopic field of view of the user using the clipping mask; and

providing the XR user interface to the user.

9 . The machine of claim 8 , wherein clipping the portion of virtual content comprises:

generating a clipping mask based on the stereoscopic field of view of the user; and

clipping the virtual content not located within the stereoscopic field of view of the user using the clipping mask.

10 . The machine of claim 9 , wherein the clipping mask is a clipping volume.

11 . The machine of claim 8 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a left monoscopic field of view by clipping the virtual content from a right virtual content rendered image of the virtual content.

12 . The machine of claim 8 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a right monoscopic field of view by clipping the virtual content from a left virtual content rendered image of the virtual content.

13 . The machine of claim 8 , wherein clipping the portion of the virtual content comprises clipping the virtual content from a left virtual content rendered image of the virtual content and a right virtual content rendered image of the virtual content.

14 . The machine of claim 8 , wherein the machine comprises a head-wearable apparatus.

15 . A non-transitory machine-readable storage medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:

generating, by at least one processor, a 3D XR user interface comprising virtual content;

determining, by the at least one processor, using 3D coordinate data of the virtual content, one or more portions of the virtual content located outside of a stereoscopic field of view of a user;

determining a near clipping plane at a first specified distance from a head-wearable apparatus worn by the user and a far clipping plane at a second specified distance from the head-wearable apparatus;

performing a conic projection from the near clipping plane to the far clipping plane, the conic projection having an opening angle using a start angle and an end angle of the stereoscopic field of view;

generating a clipping mask using the conic projection;

clipping, by the at least one processor, from the XR user interface, the one or more portions of the virtual content located outside of a stereoscopic field of view of the user using the clipping mask; and

providing, by the at least one processor, the XR user interface to the user.

16 . The non-transitory machine-readable storage medium of claim 15 , wherein clipping the portion of virtual content comprises:

generating a clipping mask based on the stereoscopic field of view of the user; and

clipping the virtual content not located within the stereoscopic field of view of the user using the clipping mask.

17 . The non-transitory machine-readable storage medium of claim 15 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a left monoscopic field of view by clipping the virtual content from a right virtual content rendered image of the virtual content.

18 . The non-transitory machine-readable storage medium of claim 15 , wherein clipping the portion of the virtual content comprises generating a monoscopic view of the virtual content in a right monoscopic field of view by clipping the virtual content from a left virtual content rendered image of the virtual content.

19 . The non-transitory machine-readable storage medium of claim 15 , wherein clipping the portion of the virtual content comprises clipping the virtual content from a left virtual content rendered image of the virtual content and a right virtual content rendered image of the virtual content.

20 . The non-transitory machine-readable storage medium of claim 15 , wherein the XR user interface is provided to the user using a head-wearable apparatus.
