1. A display system comprising:
a light projection system;
a head-mountable display configured to project light into an eye of a user to display virtual image content, the head-mountable display comprising:
at least one waveguide comprising:
a plurality of light in-coupling regions configured to receive light from the light projection system; and
a plurality of light out-coupling regions configured to output light to the eye of the user; and
processing electronics in communication with the head-mountable display and the light projection system, the processing electronics comprising one or more processors and one or more computer storage media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
determining a light out-coupling region associated with an eye pose of the eye; and
providing instructions to direct light from the light projection system to a light in-coupling region associated with the determined light out-coupling region.
