1. A method for displaying a plurality of individuals' ocular responses to a dynamic visual stimulus that changes over time, comprising the steps of: receiving data indicative of each of the plurality of individuals' ocular responses to the dynamic visual stimulus;generating, via software executing on a processor, a three-dimensional scanpath based on the data for each of the plurality of individuals, wherein two of the dimensions correspond to a position of a point of regard for each individual and one of the dimensions corresponds to time;generating, via software executing on the processor, a display of the scanpaths in a three-dimensional grid comprising two positional axes and one time axis. 2. The method of claim 1, further comprising the step of displaying an attentional funnel around the scanpaths. 3. The method of claim 1, further comprising the step of displaying a frame of the dynamic visual stimulus in the grid positioned on the time axis so as to correspond with the individuals' ocular responses to the frame. 4. The method of claim 1, wherein said step of displaying the scanpaths further comprises streaming the scanpaths to show the progression of the scanpaths as the time axis advances with time. 5. The method of claim 4, further comprising the steps of displaying an attentional funnel around the scanpaths; and streaming the attentional funnel to show the progression of the funnel as the time axis advances with time. 6. The method of claim 5, further comprising the step of displaying at least a portion of the dynamic visual stimulus such that the attentional funnel streams through the portion of the dynamic visual stimulus so that the individuals' ocular responses represented by the attentional funnel passing through the portion of the dynamic visual stimulus correspond to the frame of the dynamic visual stimulus being displayed. 7. A method for measuring the distribution of visual resources of an individual in response to a dynamic visual stimulus that changes over time, comprising the steps of: receiving data indicative of the individual's ocular responses to the dynamic visual stimulus;calculating, via software executing on a processor, an effective distribution of retinal cells for the individual;measuring points of regard on the dynamic visual stimulus over time for the individual;mapping, via software executing on the processor, the effective distribution of retinal cells onto the points of regard for the individual; andgenerating, via software executing on the processor, a display of the individual's effective distribution of retinal cells mapped onto the points of regard, the display comprising an area overlaid on the dynamic visual stimulus around at least one of the points of regard. 8. The method of claim 7, wherein said step of calculating an effective distribution of retinal cells comprises calculating an effective distribution of ganglion cells. 9. The method of claim 8, further comprising the steps of: creating a density matrix of the anatomical distribution of retinal ganglion cells;creating a density matrix of the anatomical distribution of cone photoreceptors;determining a ratio of ganglion cells to cone photoreceptors across the entire retina;multiplying the distribution of cone photoreceptors by the ratio to yield a map of effective retinal ganglion cells. 10. The method of claim 9, further comprising the step of: determining a density of cells relative to a unit of viewing angle for the individual based on the individual's field-of-view. 11. The method of claim 10, wherein the individual's field of view is one of a field-of-interest or a distance from a plane of fixation. 12. A method for quantifying and mapping visual salience to a dynamic visual stimulus that changes over time, comprising the steps of: receiving data indicative of each of a plurality of individual's ocular responses to the dynamic visual stimulus;determining, via software executing on a processor, a distribution of visual resources of the plurality of individuals with respect to at least a portion of the dynamic visual stimulus based on said data; andgenerating, via software executing on the processor, a display of the distribution of visual resources in a three-dimensional grid comprising two positional axes and one of a time axis or an axis representing a value of relative salience. 13. The method of claim 12, wherein said step of determining comprises calculating an effective distribution of retinal cells for each of at least a portion of the plurality of individuals. 14. The method of claim 13, wherein said step of determining further comprises the steps of: creating a density matrix of the anatomical distribution of retinal ganglion cells;creating a density matrix of the anatomical distribution of cone photoreceptors;determining a ratio of ganglion cells to cone photoreceptors across the entire retina;multiplying the distribution of cone photoreceptors by the ratio to yield a map of effective retinal ganglion cells. 15. The method of claim 12, wherein the three-dimensional grid comprises a time axis and the method further comprises the step of displaying a frame of the portion of the dynamic visual stimulus in the grid positioned on the time axis so as to correspond with the plurality of individual's distribution of visual resources corresponding to the frame. 16. The method of claim 12, wherein the three-dimensional grid comprises a time axis and the method further comprises the step of displaying an attentional funnel corresponding to the distribution of visual resources. 17. The method of claim 16, wherein said step of displaying the attentional funnel further comprises streaming the attentional funnel to show the progression of the attentional funnel as the time axis advances with time. 18. The method of claim 17, further comprising the step of displaying the portion of the dynamic visual stimulus on the grid such that the attentional funnel streams through the portion of the dynamic visual stimulus so that the distribution of visual resources represented by the attentional funnel passing through the portion of the dynamic visual stimulus corresponds to the frame of the portion of the dynamic visual stimulus being displayed. 19. The method according to claim 12, wherein said step of determining a distribution of visual resources includes aggregating the distributions of visual resources of each of the plurality of individuals.
