{
    glClearColor(1, 1, 0.5, 1);
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);

       glColor3f(1, 0, 0); glVertex3f(0.0, 0.0, 0.0);
       glColor3f(0, 1, 0); glVertex3f(1.0, 1.0, 1.0);
       glColor3f(0, 0, 1); glVertex3f(1.0, -1.0, 0.0);

    glEnd();

    glutSwapBuffers();
}

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