lineImproved( ) Demonstration


Draw a line by clicking and dragging on the pixel grid shown with the left mouse button. An ideal line is displayed until the left button is released. Upon release a discrete approximation of the line is drawn on the display grid using the lineImproved() method described in the previous slide. An ideal line is then overlaid for comparison.

The lineImproved() method:






Notice that the slope-intercept equation of the line is executed at each step of the inner loop.
