C program to color the different figures drawn on the console using OpenGL

In this article, the task is to create different figures on a computer screen using OpenGL.

Approach:

• In this article, in order to fill the figures with colors, different algorithms are used, so the filling can be done in the optimized pattern.
• Here, the flood fill and boundary fill algorithm with the implementation in the C++ program with the concept of sub-windows will be used.
• The mouse() function is used in the program. After running the program, use the left click to draw the image and then right-click to fill the image.

Below is the C++ program illustrating the use of OpenGL:
