Dapat tugas grafika komputer dari Dosen STIKOM AK "Mizar Firdaus Tino" nih tentang buat quads, rectangel dan triangel. Yaa semoga bermanfaat buat kalian.
nih rumusnya kita pake C++ yah. . . belajar ini kita belajar vektor vektor lagi. Matematika lagi kepake lagi tuh koordinat (x,y) nya. hayoo lah cuss. .
