1. A volumetric display comprising:
a two-dimensional display;
a varifocal optical system configured to receive image light from the two-dimensional display and focus the image light; and
at least one processor configured to:
control the two-dimensional display to cause a plurality of sub-frames associated with an image frame to be displayed by the display in an order corresponding to a depth value range of each sub-frame of the plurality of sub-frames, wherein each sub-frame of the plurality of sub-frames includes a corresponding portion of image data associated with the image frame, wherein each sub-frame includes a plurality of pixels of the image frame binned into the sub-frame based on depth values associated with the pixels, and wherein the depth value range of each sub-frame is determined based on the depth values associated with the pixels such that a first sub-frame of the plurality of sub-frames includes one or more first pixels, of the plurality of pixels, having depth values between a first depth and a second depth greater than the first depth and a second sub-frame of the plurality of sub-frames includes one or more second pixels, of the plurality of pixels, having depth values greater than the second depth; and
control the varifocal optical system to a corresponding focal state for each respective sub-frame.
