1. A computer implemented method for updating a point map on a system having a head-mounted audio-visual display component, and a torso-mounted power pack comprising a microprocessor and memory communicatively coupled to the display component, the method comprising:
the power pack dividing the point map into a plurality of point map subunits, the point map corresponding to a real-world environment surrounding the display component;
the power pack sending a first subset of the plurality of point map subunits to the display component, the first subset of the plurality of point map subunits corresponding to a first location of the display component;
the display component storing the first subset of the plurality of point map subunits;
the display component detecting a movement thereof;
the display component sending movement data to the power pack;
the display component deleting a portion of the first subset of the plurality of point map subunits based on the movement;
the power pack sending a second subset of the plurality of point map subunits to the display component in response to movement of the display component, the second subset of the plurality of point map subunits corresponding to a second location of the display component;
the display component receiving the second subset of the plurality of point map subunits; and
the display component storing the second subset of the plurality of point map subunits.
