The Discrete Equation of the Straight Line
March 1975 (vol. 24 no. 3)
pp. 310-313
A new method of description of a straight line defined on a square grid is presented. The discrete equation of the straight line (desl) is introduced as an extension of the classical Cartesian equation, and applies to straight lines quantized on a grid by the grid intersect method. The desl includes a set of intercepts which can be scanned in proper order to generate the chain for the given straight line.
Index Terms:
Chain encoding, discrete equation, discrete straight line, grid intersect, quantized line drawing.
