Product description

The provided source code demonstrates how to implement Bresenham's Line Algorithm in C++ using OpenGL and GLUT to draw a line on the screen. It initializes a window, sets up a 2D coordinate system, and draws a line from one point to another using efficient pixel plotting. The bresenhamLine function handles the line-drawing logic, calculating which pixels to fill in based on the algorithm's decision-making process. The program also includes basic setup functions for the OpenGL display window and uses the glutMainLoop() to keep the window active, displaying the drawn line.
