Atgal Veido i\u0161pjaustymas<\/h1>\n

\"Back face culling\" - tai kompiuterin\u0117s grafikos metodas, naudojamas trima\u010di\u0173 objekt\u0173 atvaizdavimo na\u0161umui pagerinti. Tai trima\u010dio objekto veid\u0173, kuri\u0173 nemato \u017ei\u016brovas, atmetimo procesas. \u0160is metodas pagr\u012fstas principu, kad veidas matomas tik tada, kai jo normalinis vektorius nukreiptas \u012f \u017ei\u016brov\u0105.<\/p>\n

Kai 3D objektas atvaizduojamas, tikrinama, ar kiekvienas objekto veidas yra nukreiptas \u012f \u017ei\u016brov\u0105, ar nuo jo. Jei veidas nukreiptas \u012f \u017ei\u016brov\u0105, jis atmetamas, o atvaizdavimo variklis pereina prie kito veido. \u0160is procesas vadinamas veid\u0173 i\u0161trynimu.<\/p>\n

\"Back face culling\" yra svarbus 3D grafikos metodas, nes jis gali gerokai pagerinti atvaizdavimo proceso na\u0161um\u0105. Atmetus nematomus veidus, atvaizdavimo variklis gali sutelkti d\u0117mes\u012f tik \u012f matom\u0173 veid\u0173 atvaizdavim\u0105, tod\u0117l suma\u017e\u0117ja skai\u010diavim\u0173, reikaling\u0173 scenai atvaizduoti, skai\u010dius. Tai savo ruo\u017etu sutrumpina laik\u0105, reikaling\u0105 scenai atvaizduoti, tod\u0117l atvaizdavimo procesas tampa efektyvesnis.<\/p>\n

Veido nugar\u0117l\u0117s i\u0161trynimas naudojamas daugelyje 3D grafikos program\u0173, \u012fskaitant vaizdo \u017eaidimus, virtuali\u0105j\u0105 realyb\u0119 ir kompiuterin\u012f projektavim\u0105 (angl.CAD<\/a>) programin\u0117 \u012franga. Tai ypa\u010d naudinga programose, kuriose reikia realaus laiko atvaizdavimo, pavyzd\u017eiui, vaizdo \u017eaidimuose, kur atvaizdavimo variklio na\u0161umas yra labai svarbus vartotojo patir\u010diai.<\/p>\n

Apibendrinant galima teigti, kad galini\u0173 veid\u0173 i\u0161trynimas yra galingas 3D grafikos metodas, naudojamas siekiant pagerinti objekt\u0173 atvaizdavimo na\u0161um\u0105. Jis grind\u017eiamas principu, pagal kur\u012f atmetami \u017ei\u016brovui nematomi objekto veidai, tod\u0117l suma\u017e\u0117ja scenai atvaizduoti reikaling\u0173 skai\u010diavim\u0173 skai\u010dius ir atvaizdavimo procesas tampa efektyvesnis.<\/p>","protected":false},"excerpt":{"rendered":"
