In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point.

The DDA Line Algorithm is a fundamental concept in Computer Graphics and Multimedia Applications (CGMA), providing a simple and computationally effective way to draw straight lines by interpolating ...

This correspondence comments on the method of circle generation described by Armstrong [1], and discusses the methods by which satisfactory circles for computer graphics may be obtained with digital ...

A straight line or line segment is the most basic operation in embedded graphical systems. It is very difficult to draw a smooth straight line as the limited screen resolution. In this paper a new ...
