Selamat siang pemirsa....!!
mau bagi bagi tugas lagi nich,hehehe....
program ini adalah tugas saya di kuliah Pemrograman Komputer Grafis membuat Garis dengan Algoritma Bressenham.Mungkin masih kurang sempurna,tapi lumayan bisa buat referensi teman teman yang mungkin lagi sibuk Ubek ubek google.program ini saya buat pake java netbeans dengan plugin OpenGL.Kalau belum ngerti cara pake OpenGL di Netbeans,bisa dibaca di sini
Langsung saja di simak source programnya
hehehehe....pusing gak bacanya ?hehehehe....
