Linux(Ubuntu 14.04) setting up OpenGL

1. Install c/c++ compilation package.

2. install openGL and freeGlut library

sudo apt-get install mesa-common-dev

sudo apt-get install freeglut3-dev

3. testing: run this code (comes from openGL red book) by save it as a cpp file. Then open the terminal and navigate to the directory containing this cpp file.

 g++ text.cpp -lglut -lGL
Then you will get an a.out. run it by

./a.out4. Done

 1 #include "GL/freeglut.h"

 2 #include "GL/gl.h"

11     glClear(GL_COLOR_BUFFER_BIT);

12     glColor3f(1.0, 1.0, 1.0);

13     glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

14     glBegin(GL_POLYGON);

16         glVertex2f(-0.5, 0.5);

17         glVertex2f(0.5, 0.5);

18         glVertex2f(0.5, -0.5);

19     glEnd();

20     glFlush();

21 }

23 /* Main method - main entry point of application

24 the freeglut library does the window creation work for us, 

25 regardless of the platform. */

28     glutInit(&argc, argv);

29     glutInitDisplayMode(GLUT_SINGLE);

30     glutInitWindowSize(500,500);

31     glutInitWindowPosition(100,100);
