Systems and Methods for Rendering Foveated Effects

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 an orientation in a three-dimensional (3D) space, wherein the orientation is based on sensor data generated by a virtual reality device;
• generating a plurality of ray footprints in the 3D space based on the determined orientation;
• for at least one ray footprint of the plurality of ray footprints:
• identifying a corresponding number of subsamples to generate for that ray footprint;
• generating one or more coordinates in the ray footprint based on the corresponding number of subsamples;
• and
• determining visibility of one or more objects defined within the 3D space by projecting a ray from each of the one or more coordinates to test for intersection with the one or more objects;
• and
• generating an image of the one or more objected based on the determined visibility of the one or more objects.

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 an orientation in a three-dimensional (3D) space, wherein the orientation is based on sensor data generated by a virtual reality device;
• generating a plurality of ray footprints in the 3D space based on the determined orientation;
• for at least one ray footprint of the plurality of ray footprints:
• identifying a corresponding number of subsamples to generate for that ray footprint;
• generating one or more coordinates in the ray footprint based on the corresponding number of subsamples;
• and
• determining visibility of one or more objects defined within the 3D space by projecting a ray from each of the one or more coordinates to test for intersection with the one or more objects;
• and
• generating an image of the one or more objected based on the determined visibility of the one or more objects.
