Mid points of line is obtained by dividing it in two short segments. Again division is done, by finding midpoint. This process is continued until line of visible and invisible category is obtained. Let (x i,y i) are midpoint
WebDrawing a circle on the screen is a little complex than drawing a line. There are two popular algorithms for generating a circle: Bresenham’s Algorithm and Midpoint Circle Algorithm. These algorithms are based on the idea of determining the subsequent points required to draw the circle. Let us discuss the algorithms in detail: WebMidpoint Subdivision Line Clipping Algorithm; Liang-Barsky Line Clipping Algorithm; Cohen Sutherland Line Clipping Algorithm: In the algorithm, first of all, it is detected whether line lies inside the screen or it is outside the screen. All lines come under any one of the following categories:
