Sep 11, 2023 · 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.

Step 1: Read the input of the 2 end points of the line as (x1, y1) & (x2, y2) such that x1 != x2 and y1 != y2. Step 2: Calculate dx = x2 – x1 and dy = y2 – y1. Step 3: if(dx>=dy) step=dx. else. step=dy. Step 4: xin = dx / step & yin ...

DDA is an easy algorithm to calculate the points on the line using integer arithmetic. DDA works by calculating the difference in y and x between the two points. It then calculates the incremental change values for each x and y pixel.

This C++ program with OpenGL visualizes the DDA line drawing algorithm. User-inputted coordinates define the line, displayed along with pixels, Cartesian grid, and a thick green line. Interactive features include moving, scaling, and rotating a square.

May 19, 2015 · Here is a simple C++ program to implement the DDA line drawing algorithm using the graphics.h library: The program begins by initializing the graphics mode using initgraph(). It prompts the user to enter the starting and ending coordinates of the line. The change in x (dx) and y (dy) is calculated.

Apr 26, 2013 · Below is a C program to implement the DDA (Digital Differential Analyzer) line drawing algorithm. DDA is a very simple line drawing algorithm that is used to draw a line on a 2D plane using two specified points like (xa, ya) and (xb, yb).
