I-Vector animation iyigama elisetyenziselwa ukubhekisela kwimifanekiso apho ubugcisa okanye ukunyakaza kulawulwa ngabahloli ngaphandle kweepekseli . I-Vector animation ivame ukuvumela ukucoceka, ukugqithisa ngokugqithiseleyo kuba imifanekiso iboniswa kwaye isatshintshile ngokusebenzisa ixabiso leemathematika endaweni yokugcina ixabiso lepikelli. Enye yeenkqubo ezisetyenziswa kakhulu kwiimpawu zee-vector yi-Adobe Flash (yangaphambili iMacromedia Flash). Ngaphambi kokuqonda inzululwazi emva kwendalo ye vector, kufuneka uqonde umehluko phakathi kweentlobo ezimbini ezibonakalayo eziphambili: i-bitmap kunye negraphic vector.
Isingeniso kwiBitmap kunye neVector Graphics
Uninzi lweentlobo zezithombe abantu abaziqhelana nazo ziquka igridi yamaphikseli apho nganye ipiliseli okanye ibinzana iqulethe ulwazi malunga nendlela umbala kufuneka uboniswe ngayo. Iifayile ze-JPEG, i-GIF kunye ne-BMP, umzekelo, zonke iimifanekiso zepikelli ezibizwa ngokuba yi- raster okanye i-bitmap imifanekiso . Le mizobo ye-bitmap, ngoko ke, inesigqibo esisigxina okanye inani leepekseli kwigridi, lilinganiswe ngamaphikseli nge intshi (PPI). Isisombululo se-bitmap sinciphisa ubungakanani befayile yesibonakaliso njengoko abanako ukuhlaziywa ngaphandle kokulahlekelwa ngumgangatho womfanekiso. Wonke umntu ugijimele kwi-bitmap eye yavuthela kude ibukeka i-blocky okanye i-pixelated.
Imifanekiso yeVector, ngakolunye uhlangothi, iqukethe iindlela ezichazwe ngethuba lokuqala neyokugqibela. Le mizila ingaba nayiphi na into esuka kumgca ukuya kumqolo weendlela ezidala umlo njengesikwere okanye isangqa. Nangona uqobo lwe-block block building, imizila ingasetyenziselwa ukudala imifanekiso enzima kakhulu. Into nganye yomzila ithatha isitatimende sayo semathematika esichaza indlela into ekufuneka iboniswe ngayo. Ezinye zeefomathi zeefayile eziqhelekileyo ziquka i-AI (Adobe Illustrator), iDXF (AutoCAD DXF), kunye neCGM (iComputer Graphics Metafile) .Iimifanekiso zeVector zingaphinda zifunyenwe kwi-EPS (i-PostScript ye-PostScript) kunye ne-PDF (Ifomathi yeFomathi yoFomathi).
Umehluko obaluleke kakhulu phakathi kwemifanekiso ye vector kunye ne-bitmap kukuba iifayile ze vector zizimeleyo ezizimeleyo, nto leyo ithetha ukuba ineneka. Ngenxa yokuba imifanekiso engabonakaliyo yenziwe ngegridi ehleliweyo njengemifanekiso ye-bitmap, inokuthi ihlaziywe ngaphandle kokulahlekelwa ngumgangatho womfanekiso. Oku kwenza ukuba zilungelelaniswe kwizixhobo ezahlukeneyo zokuyila iifayile ezifana nelogos, ezifuna ukukwazi ukuphakanyiswa kwezinto ezincinci njengekhadi leshishini okanye ukuphakanyiswa into into enkulu njengomqondiso webhodibhodi.
Vector Izithombe Basics
Nangona abanye abahleli bevector (iinkqubo zekhomputha ezenza iifayile ze-vector) zixhasa inkxaso, iiprogram ezithandwa kakhulu kwiindalo zendalo, njenge-Adobe Flash, zijoliswe ngqo kule njongo. Ngelixa iindidi ezinokuzibandakanya zingabandakanya imifanekiso ye-bitmap, ininzi isebenzisa imifanekiso egciniweyo kuphela yecatshulwa ngoba njengoko sifunde kwangaphambili, bayakwazi ukukhula ngcono kwaye ngokuqhelekileyo bathathe indawo encinane. Ezi ziboniso zentengiso zineendlela ezibonakalayo ezicocekileyo xa kuthelekiswa nezinye iindlela.
Kumazwe, kukho ezinye iifom zefayile kunye neentengiso . Ngokomzekelo, i-EVA (Extended Vector Animation) yifayile efomathi yefayile efakwe kwiJapan apho isofthiwe ye-EVA Animator isetyenziswa kakhulu. Uhlobo oluphambili phakathi kwefomathi ye-EVA kunye nezinye iifom ze vector kukuba zirekhoda kuphela utshintsho kwi-vector phezu kwexesha kunokuba urekhode ulwazi ngolwazi lwesakhelo ngasinye. Iifom ze-EVA nazo zihlala zincinci kunezinye zazo.
