Vector animation yog ib lo lus siv los xa cov animation uas cov kos duab los yog cov lus tsa los tswj los ntawm vectors es pixels . Vector animation feem ntau tso cai rau kev ntxhua khaub ncaws, smoother animation vim tias cov duab tso tawm kom pom thiab siv cov lej siv cov kev ua zauv tsis txhob siv cov pixel qhov tseem ceeb. Ib qho ntawm cov vector siv feem ntau siv vector animation yog Adobe Flash (yav tas los Macromedia Flash). Ua ntej nkag siab txog science tom qab vector animation, koj yuav tsum to taub qhov txawv nruab nrab ntawm ob hom kev nraaj loj: bitmap thiab vector graphics.
Taw qhia rau Bitmap thiab Vector Graphics
Ntau cov duab hom neeg feem ntau paub txog kev ua ib kab hauv pixels uas txhua qhov pixel lossis me ntsis muaj cov ntaub ntawv qhia txog tias yuav tsum muaj xim li cas. JPEGs, GIFs, thiab BMP dluab, piv txwv li, yog txhua yam pixel dluab hu ua raster lossis bitmap graphics . Cov duab bitmap, yog li no, muaj ib qho kev daws teeb meem los yog pes tsawg tus pixels hauv daim phiaj, ntsuas los ntawm pixels ib nti (PPI). Ib qho kev txiav txim siab bitmap txwv cov duab nraaj vim lawv tsis tuaj yeem ua kom tsis tau poob duab zoo. Txhua tus neeg tau khiav mus rau hauv ib lub tshuab bitmap uas tau tshuab tuaj txog thaum nws zoo li blocky lossis pixelated.
Vector graphics, ntawm lwm tes, muaj cov paths uas tau txhais los ntawm kev pib thiab qhov kawg. Cov kab no tuaj yeem ua txhua yam los ntawm ib txoj kab rau cov kab uas tsim cov duab zoo li lub voj voog lossis lub voj voos. Dua li ntawm qhov simplistic xwm ntawm ib lub vector lub tsev thaiv, paths yuav siv tau los tsim cov txheej txheem yooj yim. Ib qho khoom siv twg yog qhov nws muaj nws daim ntawv qhia zauv uas qhia tias qhov khoom yuav tsum tau muab tso tawm li cas. Qee hom vector ntau tshaj li AI (Adobe Illustrator), DXF (AutoCAD DXF), thiab CGM (Computer Graphics Metafile) .Vector graphics kuj muaj nyob hauv EPS (Encapsulated PostScript) thiab PDF (Portable Document Format).
Qhov tseem ceeb sib txawv ntawm vector thiab bitmap graphics yog tias vector graphics yog kev ywj pheej ywj pheej, txhais tau hais tias lawv yog qhov tseeb tiag. Vim vector graphics tsis yog ua los ntawm ib daim phiaj tsau zoo li bitmap graphics, lawv tuaj yeem ua qauv tsis tau poob duab zoo. Qhov no ua rau lawv zoo siab rau ntau hom kev tsim qauv nraaj xws li cov logos, uas yuav tsum muaj peev xwm ua kom muaj peev xwm ua qhov khoom me me zoo ib yam li ib daim npav lag luam los yog loj tuaj rau tej yam loj li ib daim ntawv sau npe.
Vector Animations Ntsiab
Hos cov vector editors (lub computer cov kev pab cuam uas compose thiab hloov vector graphics) txhawb animation, cov kev pab cuam tshaj plaws rau cov animation creation, xws li Adobe Flash, yog lawv geared rau ntawd lub hom phiaj. Thaum animations muaj xws li cov duab bitmap, feem ntau tsuas siv cov vector-based graphics vim hais tias raws li peb tau kawm ua ntej, lawv nplua zoo dua thiab feem ntau coj tsawg dua qhov chaw. Cov vector animations no feem ntau muaj kev nrheev nrig raws li lawv txoj kev xaiv.
Thoob ntiaj teb, muaj lwm hom vector thiab animators . Piv txwv, EVA (Extended Vector Animation) yog web-based vector ntaub ntawv hom nrov hauv Nyiv qhov twg EVA Animator software yog dav siv. Thawj qhov sib txawv ntawm EVA hom thiab lwm hom vector yog tias lawv sau cov kev hloov hauv vector dhau lub sijhawm es tsis txhob teev cov ntaub ntawv rau ib thav duab. EVA cov ntaub ntawv kuj yuav ua rau me dua cov uas lawv xaiv.
