DDA (Digital Differential Analyzer) Line Drawing Algorithm Explained with Notes | Computer Graphics

DDA (Digital Differential Analyzer) is a line drawing algorithm used in computer graphics to generate a line segment between two specified endpoints. It is a simple and efficient algorithm that works by using the incremental difference between the x-coordinates and y-coordinates of the two endpoints to plot the line.

The steps involved in DDA line generation algorithm are:

Input the two endpoints of the line segment, (x1,y1) and (x2,y2).
Calculate the difference between the x-coordinates and y-coordinates of the endpoints as dx and dy respectively.
Calculate the slope of the line as m = dy/dx.
Set the initial point of the line as (x1,y1).
Loop through the x-coordinates of the line, incrementing by one each time, and calculate the corresponding y-coordinate using the equation y = y1 + m(x – x1).
Plot the pixel at the calculated (x,y) coordinate.
Repeat steps 5 and 6 until the endpoint (x2,y2) is reached.
DDA algorithm is relatively easy to implement and is computationally efficient, making it suitable for real-time applications. However, it has some limitations, such as the inability to handle vertical lines and the need for floating-point arithmetic, which can be slow on some systems. Nonetheless, it remains a popular choice for generating lines in computer graphics.
