Cov nyhuv aliasing yog qhov pom ntawm cov npoo jagged lossis "jaggies" hauv cov duab rasterized(ib daim duab siv pixels). Qhov teeb meem ntawm jagged npoo technically tshwm sim vim distortion ntawm cov duab thaum scan conversion yog ua nrog sampling ntawm ib tug tsawg zaus, uas yog tseem hu ua Undersampling.
Dab tsi yog aliasing thiab anti-aliasing hauv computer graphics?
Aliasing yog qhov pom kev stair-stepping ntawm ntug uas tshwm sim hauv daim duab thaum qhov kev daws teeb meem tsawg dhau. Anti-aliasing yog qhov smoothing ntawm jagged npoo hauv cov duab digital los ntawm qhov nruab nrab ntawm cov xim ntawm cov pixels ntawm ib thaj tsam.
Yuav ua li cas alias ua piv txwv?
Aliasing: Aliasing yog hais txog qhov xwm txheej uas tib qhov chaw nco tuaj yeem nkag tau siv cov npe sib txawvPiv txwv li, yog tias ib txoj haujlwm siv ob lub pointers A thiab B uas muaj nqi ib yam, ces lub npe A[0] aliases lub npe B[0] i.e., peb hais tus pointers A thiab B alias ib leeg.
Vim li cas aliasing tshwm sim hauv cov duab?
Qhov no tshwm sim hauv cov duab ntawm txhua qhov chaw thaum tus qauv zaus poob qis dua qhov qub zaus, xws li: Thaum qhov kev ntxhib los mos raug txo qis vim nws tau saib los ntawm qhov deb. Mipmapping aims los kho qhov teeb meem no los ntawm low-pass pre-filtering textures thiab khaws cov ntawv luam hauv cov kev daws teeb meem qis.
Koj piav qhia li cas?
Hauv kev ua cov teeb liab thiab lwm yam kev qhuab qhia, aliasing yog ib qho txiaj ntsig uas ua rau cov cim sib txawv los ua qhov sib txawv tsis tau(lossis lwm tus neeg lub npe) thaum ua piv txwv.

Dab tsi yog cov installers hauv computer?
Ib qho kev teeb tsa lossis kev teeb tsa yog ib lub khoos phis tawj uas nruab cov ntaub ntawv, xws li cov ntawv thov, tsav tsheb, lossis lwm yam software, rau hauv lub computer . Qhov kev teeb tsa txhais li cas? : kev ua lossis txheej txheem ntawm kev tsim lub tshuab, kev pabcuam, thiab lwm yam, npaj siv rau hauv ib qho chaw:
Txoj cai swb hauv computer science yog dab tsi?
Txoj cai swb yog ib lub tshuab computer analog… Raws li cov thawj tswj hwm txhua tus muaj qhov ntsuas logarithmic, nws tuaj yeem ua kom haum lawv kom nyeem cov lej ntawm cov logarithms, thiab yog li suav cov khoom ntawm ob tus lej . Txoj cai swb yog dab tsi thiab nws ua haujlwm li cas?
Dab tsi yog abstraction hauv computer science?
Hauv software engineering thiab computer science, abstraction yog: cov txheej txheem ntawm kev tshem tawm lub cev, qhov chaw, lossis lub cev nqaij daim tawv lossis cov cwj pwm hauv kev kawm ntawm cov khoom lossis cov tshuab kom mob siab rau cov ntsiab lus … Dab tsi yog abstraction hauv kev suav?
Hauv computer graphics polygons?
Polygons yog siv rau hauv computer graphics kom sau cov duab uas muaj peb-dimensional nyob rau hauv tsos … yog li cov polygons yog ib theem hauv computer animation. Cov lej suav suav hais txog tus lej ntawm cov polygons tau ua rau ib tus ncej .
Kev sib koom tes hauv xov tooj hauv computer yog dab tsi?
Computer telephony integration, tseem hu ua computer-xov tooj kev koom ua ke lossis CTI, yog ib lub npe zoo rau txhua lub tshuab uas tso cai rau kev sib cuam tshuam hauv xov tooj thiab lub khoos phis tawj los ua ke lossis sib koom ua ke. Lub ntsiab lus ntawm kev sib txuas hauv computer yog dab tsi?
