Claim 0:
1. A method of directing energy based on four dimensional (4D) coordinates for content data, the method comprising:
receiving content data;
determining a location for each of a plurality of data points with respect to a first surface to create a digital volumetric representation of the content data, the first surface being a reference surface for defining the locations of data points in space;
tracing the location of each of the data points to the first surface through a plurality of locations at a second surface where energy is to be propagated therethrough in accordance to a 4D function applied at the second surface;
determining a set of 4D coordinates for each data point based on a plurality of traced intersections at the first and second surfaces;
determining a first set of energy source modulation values for a first set of 4D coordinates based on the 4D function, the first set of 4D coordinates associated with a first point of convergence at a location of a first data point; and
determining a second set of energy source modulation values for a second set of 4D coordinates based on the 4D function, the second set of 4D coordinates associated with a second point of convergence at a location of a second data point that is different than the location of the first data point;
wherein the first and second sets of 4D coordinates are determined based on different pluralities of traced intersections at the first and second surfaces; and
wherein the first set of energy source modulation values is operable to instruct an energy directing device to direct energy to the first point of convergence along a first plurality of energy propagation paths to form at least a first portion of a detectable volumetric representation of the content data, and the second set of energy source modulation values is operable to instruct the energy directing device to direct energy to the second point of convergence along a second plurality of energy propagation paths to form at least a second portion of the detectable volumetric representation of the content data;
wherein the first and second portions of the detectable volumetric representation of the content data comprise a holographic surface that is perceivable to a viewer.
