Question

Using the following code of the Simplified Bresenham algorithm, show the complete steps for drawing a line from the point (1, -3) to the point (-4, 0) in a 2D Cartesian domain.

function line(x0, y0, x1, y1)
dx := abs(x1-x0)
dy := abs(y1-y0)
if x0 < x1 then sx := 1 else sx := -1
if y0 < y1 then sy := 1 else sy := -1
err := dx-dy

loop
plot(x0,y0)
if x0 = x1 and y0 = y1 exit loop
e2 := 2*err
if e2 > -dy then
err := err - dy
x0 := x0 + sx
end if
if x0 = x1 and y0 = y1 then
plot(x0,y0)
exit loop
end if
if e2 < dx then
err := err + dx
y0 := y0 + sy
end if
end loop
