Umthumeli woxinzelelo lwedijithali, usebenzisa amacandelo avela kumazwe angaphandle oxinzelelo loxinzelelo, kunye nokumelana ne-laser yekhompyuter yembuyekezo yobushushu, kusetyenziswa uyilo oluhlanganisiweyo lwebhokisi yokuhlangana. Ngeetheminali ezikhethekileyo kunye nomboniso wedijithali, ukufakwa lula, ukulinganisa kunye nokugcinwa. Olu chungechunge lweemveliso zifanelekile kwi-petroleum, ukugcinwa kwamanzi, ushishino lweekhemikhali, isinyithi, amandla ombane, imboni yokukhanya, uphando lwezenzululwazi, ukhuseleko lokusingqongileyo kunye namanye amashishini kunye namaziko, ukuphumeza umlinganiselo woxinzelelo lwe-fluid kwaye usebenzise kwiimeko ezahlukeneyo zonke- imo yezulu kunye neentlobo ngeentlobo zolwelo oludlekayo.
