Pada tugas  kali ini kami akan membuat bentuk dasar dan bangun ruang menggunakan DevC++ dengan library openGL.

 Disini kami membuat 4 garis :

• harizontal
• vertikal
• diagonal
• garis bebas

serta kami juga membuat 3 ruang :

• Segitiga outline dan segitiga full area
• Segiempat full area  dan segitempat outline
• polygon full area dan polygon outline

Cara membuatnya pertama-tama kita buka aplikasi DevC++ kemudian kita buka library openGL dan ketikan kodingan dibawah ini :

1. Garis Harizontal

glClearColor (0.0f, 0.0f, 0.0f, 0.0f);

            glClear (GL_COLOR_BUFFER_BIT);

            glPushMatrix ();     

            glBegin (GL_LINES);

            glColor3f (128.0f, 255.0f, 0.0f); 

                                                glVertex2f (-0.8f, 0.0f);

                                                glVertex2f (0.8f, 0.0f);        

            glEnd ();

            glPopMatrix ();

            SwapBuffers (hDC);

            theta += 1.0f;

            Sleep (1);        }

    }
