Starting OpenGL

Here's a code on how to start your hello world in openGL:

#include <GL/gl.h>

#include <GL/glu.h>

#include <GL/glut.h>

void display(){

   glClear(GL_COLOR_BUFFER_BIT);

   glutWireTeapot(0.5);

   glFlush();

}

int main(int argc, char *argv[]){

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE);

    glutInitWindowSize(400, 300);    // horizontal, vertical

    glutInitWindowPosition(200, 100);    // horizontal, vertical

    glutCreateWindow("Hello World");    // title of the window

    glutDisplayFunc(display);

    glutMainLoop();

    return 0;

}
