In computer graphics, the midpoint circle algorithm is an algorithm used to determine the points needed for drawing a circle. Drawing on a computer screen is different from drawing on paper in that the paper starts out white, and all you have to do is draw the picture. We plug the Midpoint into the above F() for the line and see where the midpoint falls in relation to the line. Here i have used fillpoly function to draw the object body and used fillellipse function to draw tier. The circle is thus drawn as a series of straight lines. Takes the line co-ordinates from the user to plot the desired line. Danielsson, “Incremental Curve Generat ion”, IEEE T ransactions on Computers, vol. Explain the steps in midpoint ellipse.
