UGC NET CSE | August 2016 | Part 3 | Question: 15
Consider the Breshenham's line generation algorithm for a line with gradient greater than one, current point $(x_{ i} , y_{i} )$ and decision parameter, $d_{i}$. The next point to be plotted $(x _{i+1}, y_{i+1})$ and updated decision parameter, $d_{i+1}$ ... $x_{ i+1} = x_{ i + 1} y_{i+1} = y_{i + 1} d_{i+1} = d_{i} + 2 (dy - dx)$
