Abstract:
A method of mapping diagonal rows and columns of two-dimensional grid elements to rectangular rows and columns of two-dimensional grid elements, comprising the steps of:defining a u,v space for the diagonal rows and columns, such that the u axis and v axis run through diagonals of each grid element; assigning a u,v coordinate pair for each grid element; for each grid element in the u,v space, calculating an x,y coordinate pair, by performing the following operation: [xy]=int&it;â€ƒ&it;([0.51-0.51]&CenterDot;[uv]+[0.50.5])â€ƒand; for each non-integer value, rounding to an adjacent integer value.
