Contoh Coding Membuat Drone/Baling-Baling Pemrograman Grafis pada Java

Coding Membuat baling-baling berputar pada pemrograman grafis tidak terlalu susah. Anda hanya perlu membuat persegi, tiang, segiti. Selebihnya Anda kombinasikan objek-objek tersebut untuk membuat sebuah drone atau baling-baling.

Coding dibawah ini adalah contoh coding membuat drone atau baling-baling sederhana pada java. Anda juga bisa membuat nya lebih sempurna.



Berikut adalah coding dari cara membuat drone pada java :

import java.awt.event.WindowEvent;
import javax.media.opengl.GL;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCanvas;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.glu.GLU;
