WebThe slope of a line plays a major role in the line equation that's why Bresenham line drawing algorithm calculates the equation according to the slope of the line. The slope of the line can be greater than 1 (m>1) or less than or equal to 1 (m<=1). Now enough talking let's derive the equations.
A linear DDA starts by calculating the smaller of dy or dx for a unit increment of the other. A line is then sampled at unit intervals in one coordinate and corresponding integer values nearest the line path are determined for the other coordinate. Considering a line with positive slope, if the slope is less than or equal to 1, we sample at unit x intervals (dx=1) and compute successive y values as jewelry hooks for necklacesWebEasy Tutor author of Program to draw a line using Bresenham's Line Algorithm (BLA) for lines with slopes positive and greater than 1 is from United States.Easy Tutor says .
