Midpoint Algorithm in drawing line c++. 2. Submit a Topic In Mid-point Ellipse drawing algorithm we use 4 way symmetry of the ellipse to generate it.We perform calculations for one part and the other three parts will be drawn by using 4-way symmetry. The entire algorithm is based on the simple equation of circle X 2 + Y 2 = R 2. But as the diagonal line passes the "halfway" mark to becoming vertical, it doesn't update y and only draws the line with a smaller slope. If q j 0, the midpoint is inside the curve and we choose pixel V. If q j ≥0, the midpoint is outside the curve and we choose pixel U.Decision parameter for the next step is: q j+1 =f(x j+1 +,y j+1-1) Task.
