Sib tham sib vs Passive Graphics
Lub sij hawm computer graphics yog hais txog txhua yam uas tsis yog suab thiab cov ntawv nyeem ntawm lub computer saib. Kev txhim kho cov duab ntawm cov khoos phis tawj tau ua kom yooj yim rau cov tib neeg sib tham thiab nkag siab cov ntaub ntawv uas tsis muaj suab lossis ntawv nyeem. Khoos phis tawj duab tau muaj kev cuam tshuam loj hauv kev nkag siab tias lawv tso cai rau kev sib txuas lus zoo ntawm tib neeg thiab khoos phis tawj. Muaj ob hom computer graphics xws li kev sib tham sib computer graphics (IGU) thiab passive computer graphics. Qhov loj sib txawv ntawm ob hom yog tias thaum nyob rau hauv kev sib tham sib computer graphics cov neeg siv tuaj yeem cuam tshuam nrog cov duab thiab tuaj yeem hloov pauv hauv lawv, nws tsis tuaj yeem ua li ntawd hauv passive computer graphics i.e. Nws tsis muaj kev tswj hwm cov duab.
Muaj ntau qhov zoo ntawm cov duab sib tham sib dhau cov duab passive
• Cov duab zoo dua
• Tus nqi qis
• Kev tsim khoom siab dua
• Kev tsom xam qis
Nws muaj peb yam tseem ceeb ntawm kev sib tham hauv computer graphics uas yog, lub cim xeeb digital, saib, thiab cov tswj saib. Cov zaub yog khaws cia rau hauv lub cim xeeb digital nyob rau hauv daim ntawv ntawm binary tooj uas sawv cev rau tus kheej pixels. Thaum nws yog B&W cov duab, cov ntaub ntawv yog nyob rau hauv daim ntawv ntawm 1's thiab 0's hauv lub cim xeeb digital. Ib qho array ntawm 16 x 16 pixels tuaj yeem sawv cev siv 32 bytes khaws cia hauv lub cim xeeb digital. Nws yog cov zaub maub los uas nyeem cov ntaub ntawv no nyob rau hauv daim ntawv ntawm binary tooj thiab hloov lawv mus rau hauv video signals. Cov teeb liab no tau pub rau lub monitor uas tsim cov duab dub thiab dawb. Display controller rov hais dua cov ntaub ntawv no 30 zaug ib pliag kom khaws cov duab tsis tu ncua ntawm lub monitor. Koj li tus neeg siv tuaj yeem hloov kho cov duab los ntawm kev hloov kho kom haum rau cov ntaub ntawv khaws cia hauv lub cim xeeb digital.
