1. A method for calculating vision obstruction, comprising the steps of: providing data representing a physical environment around a human being, portions of the represented physical environment being visible to the human being as a plurality of viewing areas; establishing a centroid located between a simulated right eye and a simulated left eye of a human being; simulating light projection from the right eye and the left eye of the human being onto at least one of the plurality of viewing areas to produce at least one rendered image comprising a plurality of pixels; displaying the at least one rendered image onto at least one of the plurality of viewing areas; designating a first set of colors to represent a first plurality of objects which are visible in the at least one rendered image; designating a second set of colors to represent a second plurality of objects which are obstructed in the at least one rendered image; and determining the numbers of pixels representing the first plurality of objects which are visible and the second plurality of objects which are obstructed by: counting the number of pixels, out of a total number of the pixels in at least one of the plurality of viewing areas, to represent what is visible to the right eye only, the left eye only, and the right eye and the left eye; designating a first portion of the counted number of pixels to represent each of the first plurality of objects visible to the right eye; designating the first portion of the pixels representing each of the first plurality of objects visible to the right eye to have a first color of the first set of colors; designating a second portion of the counted number of pixels to represent each of the first plurality of objects visible to the left eye; and designating the second portion of the pixels representing each of the first plurality of objects visible to the left eye to have a second color of the first set of colors; calculating a percentage of the at least one rendered image visible to the right eye by dividing the first portion of the pixels representing each of the first plurality of objects visible to the right eye by a total number of the pixels; and calculating a percentage of the at least one rendered image visible to the left eye by dividing the second portion of the pixels representing each of the first plurality of objects visible to said left eye by the total number of the pixels.
