Dab tsi yog qhov graphics ntawm lub computer

Hais txog cov duab zoo li cas, thiab cov duab zoo li cas zoo dua, koj tuaj yeem sib tham txog cov xuab moos, ib yam nyob ntawm tib - siv lub computer los ua ib qho cuab yeej tsim cov duab cia rau koj sai sai thiab zoo rau qhov kev xav tau.

Ib tug neeg nyiam dub thiab dawb graphics, ib tug neeg - xim, ib tug neeg nyob hauv nruab nrab, thiab yuav zoo siab rau qhov ntxoov txho. Nrog lub advent ntawm lub computer yuav tsum tau ntsib cov ntsiab lus tshiab: raster, vector thiab fractal graphics.

Koj nug: "Vim li cas?" Lub sij hawm vim hais tias yog nws. Graphics, tshwj xeeb tshaj yog khoos phis tawj, yog siv ntau yam ntawm cov neeg ua haujlwm.

Nrog raster graphics txhua yam yog yooj yim - cov duab muaj matrix ntawm cov ntsiab lus, txhua tus uas muaj ib tug cim xeeb ceem - qhov no yog nws cov xim. Qhov zoo ntawm daim duab no cuam tshuam los ntawm ob tug tsis - qhov kev daws teeb meem thiab pes tsawg tus xim uas siv hauv daim duab. Rau lub raster graphics yog yus muaj los ntawm tsis zoo nrog ib qho kev nce nyob rau hauv lub loj ntawm cov duab, tab sis koj yuav pleev xim li xim nyob rau album.

Tab sis nrog dab tsi yog vector graphics, nws yog tsim nyog tshawb xyuas nyob rau hauv ntau dua kom meej. Yog li, vector graphics yog ib phau ntawm cov khoom uas sawv cev thiab muab khaws cia rau hauv daim ntawv ua zauv. Piv txwv, lub voj voog yog muab los ntawm cov chaw nruab nrab ntawm lub plawv thiab lub vojvoog, duab plaub los ntawm cov kab sib chaws ntawm cov kab lus sib txawv, txoj kab ntawm lub khos ntawm pib thiab xaus ntawm ntu, thiab ntxiv rau. Cov khoom no kuj yog cov hom kab contour (khoom los yog dashed), cov xim ntawm cov kab contour, xim ntawm tus sau, lub xub ntiag thiab hom kev khawm, thiab ntxiv rau. Txhua yam khoom tsim tshiab ua kom obscures yav dhau los, tab sis lawv tsis ploj tsis muaj qhov cim tseg, thiab, yog tias tsim nyog, lawv tuaj yeem rub mus rau pem hauv ntej tsis muaj kev piam sij. Yuav ua li cas yuav tsis ua tau nrog ib tug bitmap duab.

Feem ntau, vector graphics yog siv rau kev luam, tsim cov ntaub ntawv txhawb. Vector dluab teb zoo hloov qhov luaj li cas tej zaum yuav tau nce tsis pab cov duab zoo. Lub disadvantage ntawm vector graphics yog ib tug loj loj loj ntawm thawj cov ntaub ntawv nrog graphics, raws li ib txoj cai, tsis zoo compressible.

Mus ua hauj lwm nrog vector graphics, muaj ib tug xov tooj ntawm tshwj xeeb duab editors, mus rau leej twg yog, piv txwv li, Corel lub kos, raws li tsev av tuav thiab lwm tus neeg. Txawm tias lub teeb vaj huam sib luag hauv Microsoft Word kuj yog ib qho kev tsim vector graphics editor. Tab sis, zoo li cas hauv graphics thiab lo lus hauv cov software tshwj xeeb? Qhov no, raws li lawv hais, ob qhov sib txawv loj.

Zoo, fractal graphics , tsis zoo li yav dhau los hom tsis muab rau lub cia ntawm pixels nyob rau hauv lub cim xeeb. Daim duab yog ua raws nraim li ib qho kev ua lej algorithm uas muaj kev sib npaug thiab cov qauv. Nrog kev pab los ntawm fractal graphics, koj muaj peev xwm tsim tau zoo nkauj heev thiab txoj qauv, uas yog cov nyuaj rau kev ua tiav kev cai.

Tam sim no teb cov nqe lus nug txog cov duab zoo li cas thiab qhov twg nws tuaj yeem ua ke, yuav tsis yooj yim. Graphics puag ncig peb txhua txhua hnub: hauv TV, hauv ntawv xov xwm, tom tsev, nws tso cai rau peb kom muaj xim rau peb lub neej, ua kom nws muaj txiaj ntsig thiab nthuav.
