Scan Conversion of an Ellipse: An ellipse can be defined as a closed plane curve, which is a collection of points. It is the cause of the intersection of a plane over a cone. The ellipse is a symmetric shape figure. It is similar to a circle, but it contains four-way...

Filled Area Primitives: Area filling is a method or process that helps us to fill an object, area, or image. We can easily fill the polygon. The polygon filling is defined as filling or highlighting all the pixels. The pixels appear inside the polygon shape with any...

The midpoint circle drawing algorithm helps us to calculate the complete perimeter points of a circle for the first octant. We can quickly find and calculate the points of other octants with the help of the first octant points. The remaining points are the mirror...

“When we represent regular objects in the form of discrete pixels, it is called Scan Conversion.” Every graphics system must transform the primitives into a collection of pixels. The scan conversion is also called “Rasterization.” Each pixel in the graphical system...

A circle is an eight-way symmetric shape. All quadrants of a circle are the same. There are two octants in each quadrant of a circle. If we know the value of any point, then we can easily calculate the values of the remaining seven points by using the eight-way...

The Mid-point Subdivision algorithm is the extension of the Cyrus-Beck algorithm. The Mid-Point line plotting algorithm was introduced by “Pitway and Van Aken.” It is an incremental line drawing algorithm. In this algorithm, we perform incremental calculations. The...

This algorithm was introduced by “Jack Elton Bresenham” in 1962. This algorithm helps us to perform scan conversion of a line. It is a powerful, useful, and accurate method. We use incremental integer calculations to draw a line. The integer calculations include...

Bresenham’s algorithm is also used for circle drawing. It is known as Bresenhams’s circle drawing algorithm. It helps us to draw a circle. The circle generation is more complicated than drawing a line. In this algorithm, we will select the closest pixel position to...

“The Line drawing algorithm is a graphical algorithm which is used to represent the line segment on discrete graphical media, i.e., printer and pixel-based media.” A line contains two points. The point is an important element of a line. Properties of a Line Drawing...
