WebI'm supposed to extend Bresenham's line algorithm for a university assignment so that it's able to draw lines in all octants. I was able to come up with working code for the first and third quadrant (so first, second, fifth and sixth octant). However I'm completely struggling getting it to work for the second and the fourth quadrant.
