Systems and Methods for Reducing Rendering Latency

One or more computer-readable non-transitory storage media embodying software that is operable when executed to cause one or more processors to perform operations comprising:

• determining a first orientation of a viewer in a three-dimensional (3D) space, wherein the first orientation is based on first sensor data generated by a virtual reality device at a first time;
• determining a first visibility of one or more objects defined within the 3D space by projecting rays based on the first orientation of the viewer to test for intersection with the one or more objects;
• generating one or more first lines of pixels based on the determined first visibility of the one or more objects;
• outputting the one or more first lines of pixels for display by the virtual reality device;
• determining a second orientation of the viewer in the 3D space, wherein the second orientation is based on second sensor data generated by the virtual reality device at a second time that is subsequent to the first time;
• determining a second visibility of the one or more objects defined within the 3D space by projected rays based on the second orientation of the viewer to test for intersection with the one or more objects;
• generating one or more second lines of pixels based on the determined second visibility of the one or more objects;
• and
• outputting the one or more second lines of pixels for display by the virtual reality device;
• wherein the one or more second lines of pixels associated with the second orientation of the viewer are displayed concurrently with the one or more first lines of pixels associated with the first orientation of the viewer.

A system comprising:

• one or more processors and one or more computer-readable non-transitory storage media coupled to one or more of the processors, the one or more computer-readable non-transitory storage media comprising instructions operable when executed by one or more of the processors to cause the system to perform operations comprising:
• determining a first orientation of a viewer in a three-dimensional (3D) space, wherein the first orientation is based on first sensor data generated by a virtual reality device at a first time;
• determining a first visibility of one or more objects defined within the 3D space by projecting rays based on the first orientation of the viewer to test for intersection with the one or more objects;
• generating one or more first lines of pixels based on the determined first visibility of the one or more objects;
• outputting the one or more first lines of pixels for display by the virtual reality device;
• determining a second orientation of the viewer in the 3D space, wherein the second orientation is based on second sensor data generated by the virtual reality device at a second time that is subsequent to the first time;
• determining a second visibility of the one or more objects defined within the 3D space by projected rays based on the second orientation of the viewer to test for intersection with the one or more objects;
• generating one or more second lines of pixels based on the determined second visibility of the one or more objects;
• and
• outputting the one or more second lines of pixels for display by the virtual reality device;
• wherein the one or more second lines of pixels associated with the second orientation of the viewer are displayed concurrently with the one or more first lines of pixels associated with the first orientation of the viewer.
