First Glut Program

with 0 Comment
// My first Glut Program
// Simple introductory opengl program #include <GL/glut.h>
void display(void)
{
 glClear (GL_COLOR_BUFFER_BIT);
 glColor3f (1.0,0.0,1.0);
 glBegin (GL_POLYGON);
  glVertex3f (0.25, 0.25, 0.0);
  glVertex3f (0.75, 0.25, 0.0);
  glVertex3f (0.75, 0.75, 0.0);
  glVertex3f (0.25, 0.75, 0.0);
  glEnd();
  glFlush();
}
void init(void)
{
 glClearColor (0.0, 0.0, 0.0, 0.0);
 glMatrixMode(GL_PROJECTION);
 glLoadIdentity();
 glOrtho(0.0, 1.0, 0.0, 1.0, -1.1, 1.0);
}
int main(int argc, char** argv)
{
 glutInit(&argc, argv);
 glutInitDisplayMode( GLUT_SINGLE| GLUT_RGB);
 glutInitWindowSize(250,250);
 glutInitWindowPosition(100,100);
 glutCreateWindow ("First Program");
 init();
 glutDisplayFunc(display);
 glutMainLoop();
 return 0;
}

Programming = = Computer Language
Computer Language = = Communicate with myself, no need to be understood.

HOW SAD :'(
