Dda line drawing algorithm with example. Here you will learn about dda line drawing algorithm in C and C++. Mar 17, 2025 · Program to implement DDA Line Drawing Algorithm: Output: Symmetrical DDA: The Digital Differential Analyzer (DDA) generates lines from their differential equations. 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. Before continuing with the algorithm, let’s recall the line equation. Jul 23, 2025 · Introduction : DDA (Digital Differential Analyzer) is a line drawing algorithm used in computer graphics to generate a line segment between two specified endpoints. Example: A line has a starting point (1,7) and ending point (11,17). Slope Calculation Slope (m): The slope of the line between two points (x 1, y 1) and (x 2, y 2) is calculated using the formula: Jun 8, 2021 · A line in computer graphics is usually defined by two endpoints. In Computer Graphics the first basic line drawing algorithm is Digital Differential Analyzer (DDA) Algorithm. However, most line-drawing algorithms calculate the slope and y- intercept as intermediate outputs. The DDA (Digital Differential Analyzer) algorithm is, despite its long and impressive name, the obvious way to draw a line. The equation of a straight line is The DDA works on the principle that we simultaneously increment x and y by small steps proportional to the first derivatives of x and y. Solution: We have two coordinates, Explore the Line Generation Algorithm in Computer Graphics to understand how lines are drawn on a screen using different techniques like DDA and Bresenham's algorithm. Since we are looking at lines whose increase in y is less than their increase in x, the simple solution is to start with a pixel at (x0, y0) and then loop increasing x by one each time and y by the slope, and then rounding . DDA stands for Digital Differential Analyzer, which works by calculating the intermediate points required to draw a line between two points on the screen.
