1. A wearable augmented reality display system comprising:

  • a head-mounted augmented reality display comprising;

    a waveguide stack comprising a plurality of waveguides, wherein each waveguide of the plurality of waveguides comprises;

    in-coupling diffractive optical elements configured to in-couple light, andout-coupling diffractive optical elements configured to out-couple light to an eye of a wearer of the head-mounted augmented reality display,wherein one or more waveguides of the plurality of waveguides are configured to output light with a different amount of wavefront divergence than one or more other waveguides of the plurality of waveguides, wherein the different amounts of wavefront divergence correspond to different depth planes; and

    at least one outward looking camera configured to capture an image of at least a portion of the world around the wearer,wherein the display system is configured to;

    process the image;

    re-render the image; and

    project the re-rendered image from the waveguide stack of the head-mounted display to the eye of the wearer.
