Non-uniform stereo rendering
Examples of the disclosure describe systems and methods for recording augmented reality and mixed reality experiences. In an example method, an image of a real environment is received via a camera of a wearable head device. A pose of the wearable head device is estimated, and a first image of a virtual environment is generated based on the pose. A second image of the virtual environment is generated based on the pose, wherein the second image of the virtual environment comprises a larger field of view than a field of view of the first image of the virtual environment. A combined image is generated based on the second image of the virtual environment and the image of the real environment.
1. A method comprising:
receiving a combined image, wherein:
the combined image is generated based on an image of a virtual environment and an image of a real environment,
the image of the real environment has a first field of view,
the image of the virtual environment has a second field of view different from the first field of view, and
said generating the combined image comprises performing a planar projection, said planar projection comprising mapping a point of the image of the virtual environment to a corresponding point of the image of the real environment; and
presenting, on a display, the combined image.
2. The method of claim 1 , further comprising:
receiving a cropped image, the cropped image generated based on one or more of the image of the virtual environment and the image of a real environment; and
presenting, on the display, a stereoscopic image based on the cropped image.
3. The method of claim 2 , wherein the cropped image has a field of view smaller than the field of view of the image of the virtual environment.
4. The method of claim 2 , wherein the image of the virtual environment is associated with a framebuffer size, and wherein the cropped image is associated with the same framebuffer size.
5. The method of claim 1 , wherein the image of the virtual environment comprises an aspect ratio, and wherein the image of the real environment comprises the same aspect ratio.
6. The method of claim 1 , wherein the image of the real environment comprises a first resolution and the image of the virtual environment comprises a second resolution different from the first resolution.
7. The method of claim 1 , further comprising receiving the image of the real environment via a camera.
8. The method of claim 7 , wherein the camera is configured to be placed to a left side of a user's left eye.
9. The method of claim 7 , wherein the camera is configured to be placed to a right side of a user's right eye.
10. The method of claim 7 , wherein the camera is configured to be placed in between a user's left eye and the user's right eye.
11. The method of claim 1 , wherein:
said generating the combined image comprises generating the combined image via a first device, and
a second device, different from the first device, comprises the display.
12. The method of claim 1 , wherein:
said generating the combined image comprises generating the combined image via a first device, and
the first device comprises the display.
13. The method of claim 1 , wherein the first field of view is greater than the second field of view.
14. The method of claim 1 , wherein the second field of view is greater than the first field of view.
15. A system comprising:
a display; and
one or more processors configured to perform a method comprising:
receiving a combined image, wherein:
the combined image is generated based on an image of a virtual environment and an image of a real environment,
the image of the real environment has a first field of view,
the image of the virtual environment has a second field of view different from the first field of view, and
said generating the combined image comprises performing a planar projection, said planar projection comprising mapping a point of the image of the virtual environment to a corresponding point of the image of the real environment; and
presenting, on the display, the combined image.
16. The system of claim 15 , wherein the image of the real environment comprises a first resolution and the image of the virtual environment comprises a second resolution different from the first resolution.
17. The system of claim 15 , further comprising a camera, wherein the method further comprises receiving the image of the real environment via the camera.
18. The system of claim 15 , further comprising a first device and a second device, wherein:
said generating the combined image comprises generating the combined image via the first device, and
the second device, different from the first device, comprises the display.
19. The system of claim 15 , further comprising a first device, wherein:
said generating the combined image comprises generating the combined image via the first device, and
the first device comprises the display.
20. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform a method comprising:
receiving a combined image, wherein:
the combined image is generated based on an image of a virtual environment and an image of a real environment,
the image of the real environment has a first field of view,
the image of the virtual environment has a second field of view different from the first field of view, and
said generating the combined image comprises performing a planar projection,
said planar projection comprising mapping a point of the image of the virtual environment to a corresponding point of the image of the real environment; and
presenting, on a display, the combined image.
