Abstract: A head mounted display (HMD) comprises an eye tracking system configured to perform a calibration process using an eye tracking system of the HMD that includes determining a pupillary axis and/or determining an angular offset between the pupillary axis and the eye's true line of sight. The eye tracking system obtains an eye model captures images of the user's pupil while the user is looking at a target or other content displayed on the HMD. In some embodiments, the calibration process is based on a single image of the user's eye and is performed only once. For example, the process can be performed the first time the user uses the HMD, which stores the calibration data for the user in a memory for future use.

Abstract: In one embodiment, a method for determine visibility may perform intersection tests using block beams, tile beams, and rays. First, a computing system may project a block beam to test for intersection with a first bounding volume (BV) in a bounding volume hierarchy. If the beam fully contains BV, the system may test for more granular intersections with the first BV by projecting smaller tile beams contained within the block beam. Upon determining that the first BV partially intersects a tile beam, the system may project the tile beam against a second BV contained within the first BV. If the tile beam fully contains the second BV, the system may test for intersection using rays contained within the tile beam. The system may project procedurally-generated rays to test whether they intersect with objects contained within the second BV. Information associated with intersections may be used to render a computer-generated scene.

The apparatus may also reconfigure the integral display in response to receiving updated bit-depth assignment data. Various other methods, systems, and computer-readable media are also disclosed.
