Vector animation ndigwiritsiridwa ntchito kutanthauzira zojambula zomwe zojambulajambula kapena kuyenda zikulamulidwa ndi vectors osati ma pixel . Vector animation nthawi zambiri amalola kutentha, kosavuta chifukwa zithunzi zimawonetsedwa ndikukhazikitsidwa pogwiritsa ntchito masamu m'malo mmalo osungidwa a pixel. Imodzi mwa mapulogalamu otchuka a vector ndi Adobe Flash (kale Macromedia Flash). Musanazindikire sayansi ya vector animation, muyenera kumvetsa kusiyana pakati pa mitundu iwiri yojambulajambula: bitmap ndi vector graphics.
Mau oyamba a Bitmap ndi Vector Graphics
Mitundu yambiri ya mafano omwe amadziwika bwino ndi ojambulidwa ndi gridi ya pixel imene pixel iliyonse kapena bit ndi chidziwitso cha momwe mtunduwo uyenera kuwonetsedwera. Zithunzi za JPEGs, GIFs, ndi BMP, mwachitsanzo, ndizo zithunzi zonse za pixel zomwe zimadziwika ngati zithunzi za raster kapena bitmap . Mafilimu awa a bitmap, motero, ali ndi chiganizo chokhazikika kapena nambala ya pixeleri mu gridi, yoyezedwa ndi pixels per inchi (PPI). Chisankho cha bitmap chimachepetsa kukula kwa zithunzi zomwe sangathe kusinthidwa popanda kutaya khalidwe lachifaniziro. Aliyense wathamangira ku bitmap yomwe yawombera mpaka iyo ikuwoneka yotetezedwa kapena yopopedwa.
Zithunzi za Vector, kumbali inayo, zimakhala ndi njira zomwe zimatanthauzidwa ndi chiyambi ndi mapeto. Njira izi zingakhale chirichonse kuchokera mzere mpaka mndandanda wa mizere yomwe imapanga mawonekedwe ngati ozungulira kapena bwalo. Mosasamala kanthu kowoneka mosavuta kwa nyumba yomanga nyumba, njira zingagwiritsidwe ntchito popanga zithunzi zovuta kwambiri. Cholinga chilichonse chimanyamula mawu ake a masamu omwe amasonyeza momwe chinthucho chiyenera kuwonetsedwera. Zina mwa mawonekedwe omwe amagwiritsidwa ntchito kwambiri ndi AI (Adobe Illustrator), DXF (AutoCAD DXF), ndi CGM (Computer Graphics Metafile) .Mafilimu a Vector angapezekanso mawonekedwe a EPS (Encapsulated PostScript) ndi PDF (Portable Document Format).
Kusiyana kwakukulu pakati pa vector ndi bitmap zithunzithunzi ndikuti zithunzi za vector ndizokhazikika paokha, kutanthauza kuti zowoneka bwino. Chifukwa zithunzi zojambula sizinapangidwe ndi galasi monga bitmap, akhoza kusinthidwa popanda kutaya khalidwe lachifanizo. Izi zimawapangitsa kukhala abwino kwa zojambula zojambulajambula zosiyanasiyana monga logos, zomwe zimafuna kukula kwa chinthu chaching'ono ngati khadi la bizinesi kapena kukula kwa chinachake chachikulu ngati chizindikiro cha billboard.
Vector Animations Basics
Ngakhale olemba mapulogalamu ena (mapulogalamu a makompyuta omwe amalemba ndi kusintha zithunzi zojambulajambula) zothandizira zithunzithunzi, mapulogalamu otchuka kwambiri ozilenga, monga Adobe Flash, ali ndi cholinga chenicheni. Ngakhale zojambula zingakhale ndi zithunzi za bitmap, zambiri zimagwiritsa ntchito zithunzi zokhazokha chifukwa monga taphunzira poyamba, zimakhala bwino komanso zimatenga malo ochepa. Zithunzi zojambula zithunzizi zimakhala ndi maonekedwe oyeretsa poyerekeza ndi njira zawo.
Padziko lonse lapansi, pali zowonjezera zojambulajambula. Mwachitsanzo, EVA (Extended Vector Animation) ndi mawonekedwe a mafayilo a webusaiti otchuka ku Japan komwe pulogalamu ya EVA Animator imagwiritsidwa ntchito kwambiri. Kusiyanitsa kwakukulu pakati pa mawonekedwe a EVA ndi mawonekedwe ena a vector ndikuti amangolemba kusintha kokha pa vector pa nthawi m'malo molemba zinthu pazithunzi. Maofesi a EVA amakhalanso ang'onoang'ono kusiyana ndi njira zawo.
