1. An energy waveguide system for defining a plurality of energy propagation paths comprising:
an array of energy waveguides, the array comprising a first side and a second side, and being configured to direct energy therethrough along a plurality of energy propagation paths extending through a plurality of energy locations on the first side;
wherein a first subset of the plurality of energy propagation paths extend through a first energy location and a first energy waveguide of the array of energy waveguides, wherein the first subset of the plurality of energy propagation paths fill at least a portion of an aperture of the first energy waveguide and extend towards the second side of the array in a first direction which is determined at least by the first energy location, the first subset of the plurality of energy propagation paths comprising a chief ray path and additional paths that are substantially parallel to the chief ray path on the second side of the array; and
wherein each waveguide of the array of waveguides comprises a shape of a set of one or more shapes configured to tessellate across a transverse plane of the energy waveguide system, the array of energy waveguides being arranged in a tiling of the one or more shapes across the transverse plane of the energy waveguide system, wherein the tiling of the energy waveguides results in the energy waveguides across the tiling operable to propagation energy differently depending on the configuration of each energy waveguide.
