OS used: Ubuntu

OpenGL installation on Ubuntu:

1. sudo apt-get update
2. sudo apt-get install freeglut3
3. sudo apt-get install freeglut3-dev
4. sudo apt-get install g++ cmake
5. sudo apt-get install libglew-dev
6. sudo apt-get install g++
7. sudo apt-get install mesa-common-dev
8. sudo apt-get install build-essential
9. sudo apt-get install libglew1.5-dev libglm-dev

After your development libraries have been installed to get information about the OpenGL and GLX implementations running on a given X display.

glxinfo | grep OpenGL

To Compile and Execute the C / C++ Program

1. g++ filename.cpp -lglut -lGL -lGLEW -lGLU -o filename
2. ./filename

Basic Structure of OpenGL code

	#include<iostream>
	#include<GL/glut.h>
	
	void Draw(){
		glClear(GL_COLOR_BUFFER_BIT);
		
		glPointSize(5);
		
		glBegin(GL_POINTS);
			glVertex2f(0,0);
		glEnd();
		glFlush();
	}
	
	int main(int c, char*V[]) {
		glutInit(&c,V);
		glutInitWindowSize(500,700);	
		glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);
		glutCreateWindow("Basic opengl program");
		
		glClearColor(0,0,0,1);	
		glColor3f(1,1,1);
		glutDisplayFunc(Draw);
		glutMainLoop();
		
		return 0;
	}

Assignment and Problem Statement

ASSIGNMENT	PROBLEM STATEMENT
Assignment 2	Implement DDA and Bresenham line drawing algorithm to draw: i) Simple Line ii) Dotted Line iii) Dashed Line iv) Solid line; using mouse interface Divide the screen in four quadrants with center as (0, 0). The line should work for all the slopes positive as well as negative.
Assignment 3	Implement Bresenham circle drawing algorithm to draw any object.The object should be displayed in all the quadrants with respect to center and radius
Assignment 4	Implement the following polygon filling methods : i) Flood fill / Seed fill ii) Boundary fill ; using mouse click, keyboard interface and menu driven programming
Assignment 5	Implement Cohen Sutherland polygon clipping method to clip the polygon with respect the viewport and window. Use mouse click, keyboard interface
Assignment 6	Implement following 2D transformations on the object with respect to axis i) Scaling ii) Rotation about arbitrary point iii) Reflection
Assignment 7	Generate fractal patterns using i) Koch Curve
