Mitundu ya Zojambula Computer

Mitundu makompyuta chiyani? Pali magulu awiri chachikulu cha zithunzi ntchito makampani kompyuta: awiri azithunzi omwe tikunena (2D) ndi atatu azithunzi omwe tikunena (3D). zithunzi 2D Nayenso lagawidwa vekitala ndi raster. Yesetsani kumvetsa zimene mitundu makompyuta zosiyana Chrixitu.

raster zithunzi

Tiyeni tiyambe ndi mtundu raster. Mu chilungamo tisaiwale kuti CG maziko nawuyika bitmaps. Njira imeneyi kupanga mafano ntchito gululi wa pixels, aliyense mchitidwe waika mwa magawo (kuyera, mtundu code, mlingo wa chilungamo) ubwino kwambiri, komanso kupitiriza ubwino, kuipa palibe zazing'ono.

Kumva mfundo za kupanga mauna anakulunga kulephera kuwonjezera kapena kuchepa fano chifukwa. Ngati kwambiri yafupika, zinthu otayika, ngati kuchuluka, adzaoneka wokhala pixelation. Mukufuna kufufuza? Tsitsani ku Internet chithunzi chilichonse ndi kusolola kuti phindu pazipita kuti adzakupatsani kusintha. Ngati inu kutsegula mu utoto yachibadwa - pali yayikulu njira 800%, basi zimene mukufuna.

Kodi chidwi, ndi mwayi waukulu "dontho" kunamuthandiza waukulu ali, raster chithunzi safuna kuwerenga nthawi iliyonse. Wokwanira kamodzi kubweretsa kompyuta, ndiye udzasugidwa kumeneko zikutsatiridwa, omwe si vekitala zithunzi zimene timakumana nawo mu gawo lachiwiri la nkhaniyi.

Ikani bitmap zithunzi ali paliponse: ntchito yofalitsa mabuku, pa TV, masewera a pakompyuta ndi mafilimu a kanema, chabwino, ndipo, ndithudi, Internet.

vekitala zithunzi

Creation makompyuta ntchito ma aligorivimu processing vekitala amapereka wojambula ndi mwayi waukulu. Images akhoza momasuka zimayenda ndi scaled, motero alibe kupotoza kapena kuwonongeka mu khalidwe la mankhwala chifukwa zimachokeradi. Koma Chiwerengerochi ali anafika mtengo ndithu mkulu. Nthawi iliyonse kusintha chithunzi izo recalculated, kotero kuti pamene ambiri zinthu zosiyana vekitala pa zenera, chifukwa redrawing munthawi yomweyo kungafune kwambiri processing mphamvu.

Chifukwa cha kulunjika vekitala ake zithunzi zimagwiritsa ntchito kamangidwe ka Logos, mu zilembo pamene kujambula otchulidwa zojambula kwa mndandanda, malonda, kapangidwe etc.

Atatu azithunzi omwe tikunena zithunzi.

Mitundu ngati makompyuta onse raster ndi vekitala akhoza kulankhula mpaka kalekale, koma pali zambiri zosangalatsa mtundu - atatu azithunzi omwe tikunena zithunzi.

Ngati m'mbuyomu awiri, ooneka enieni embodiments, aliyense mchitidwe chithunzi akufotokozedwa yekha mu ndondomeko awiri mu 3D kufotokoza udindo wa mfundo kale amafuna ndondomeko zitatu. Motero, kuti kuchokera lalikulu kukopedwa pa pepala kuti kyubu kuti magawo ake alipo ayenera kuwonjezera chimodzi chokha zina.

Ngati inu mwaziwona filimu yotchuka "Avatar", ndiye inu mukhoza kufuna kudziwa kuti iye anali kwathunthu analengedwa pa kompyuta ntchito zithunzi atatu azithunzi omwe tikunena. Ndipo pafupifupi onse awonekere PC chophimba ndi kutonthoza masewera ofanana ndi akonzi a zanyengo atatu azithunzi omwe tikunena. zithunzi 3D kumafuna kompyuta mphamvu adzayankha magawo a fano anasonyeza, choncho lekani kwa miniti kufunafuna mipata konza ndi imathandizira ntchito ndi mtundu uwu. Koma, mwatsoka, chitukuko kwambiri njira apambana pa kwambiri. Kuchuluka mphamvu processing zithunzi makadi, ndi kuchuluka ndalama yokumbukira ndi purosesa pafupipafupi.

Pomaliza

Mitundu yonse ya zithunzi kompyuta ntchito kulikonse. Kotero kuti kuphunzira mbali iyi zochita za anthu - kothandiza kwambiri ndipo zingamuthandize thupi.
