Patent ID: 8407269

Claim:
A computer executable method of processing a representation of a modal interval spherical projection comprising the steps of: a. providing an azimuthal projection unit for receiving a representation of a vector comprised of modal intervals X, Y, and Z, each modal interval of said modal intervals delimited by first and second marks of a digital scale; b. using said azimuthal projection unit to receive said representation of a vector comprised of modal intervals X, Y, and Z, each modal interval of said modal intervals delimited by first and second marks of a digital scale; c. using said azimuthal projection unit to partition an analytical expression of an azimuthal spherical projection into a pair of independent functions, a function of said pair of independent functions exhibiting a monotonicity over piecewise domains of said function; and, d. using said azimuthal projection unit to perform a modal interval analysis upon said function of said pair of independent functions wherein arguments of said piecewise domains are modal intervals, said modal interval analysis upon said function being predicated upon creation of a bit mask characterized by bit patterns of each first and second marks of each modal interval of said modal intervals X, Y, Z.
