I-Vector animation iyigama elisetshenziselwa ukubhekisela kwi-animation lapho ubuciko noma ukunyakaza kulawulwa yi-vectors kunama- pixel . I-Vector izithombe ngokuvamile ivumela izithombe ezihlanzekile, ezipholile ngoba izithombe zikhonjiswa futhi zishintsha kabusha ngokusebenzisa amanani wezinombolo esikhundleni samanani we-pixel agcinwe. Enye yezinhlelo ezivame ukusetshenziswa kakhulu ze-vector izithombe yi-Adobe Flash (eyayisendulo i-Macromedia Flash). Ngaphambi kokuqonda isayensi ngemuva kwe-vector animation, kufanele uqonde umehluko phakathi kwezinhlobo ezimbili eziyinhloko zemifanekiso: i-bitmap ne-vector ihluzo.
Isingeniso kwi-Bitmap ne-Vector Graphics
Izinhlobo eziningi zesithombe abantu abazijwayele kakhulu zihlanganisa igridi yama-pixel lapho i-pixel ngayinye noma i-bit ngayinye iqukethe ulwazi mayelana nokuthi umbala kufanele uboniswe kanjani. Ama-JPEG, ama-GIF, nama-BMP, isibonelo, zonke izithombe ze-pixel eziziwa njengehluzo ze- raster noma ze-bitmap . Lezi zihluzo ze-bitmap, ngakho-ke, zinokulungiswa okuhleliwe noma inombolo yamaphikseli egridi, kulinganiswa ngamaphikseli ngamasentimitha angu-intshi (PPI). Isixazululo se-bitmap sikhawulela usayizi wesithombe njengoba zingenakushintshwa kabusha ngaphandle kokulahlekelwa ikhwalithi yesithombe. Wonke umuntu ugijimise ku-bitmap eye yaqhutshwa kuze kube yilapho ibonakala ivulekile noma iphaxisiwe.
I-Vector ihluzo, ngakolunye uhlangothi, iqukethe izindlela ezichazwe yisiqalo sokuqala nesiphetho. Lezi zindlela zingaba yizinto ezivela emgqeni kuya ochungechungeni lwemigqa eyenza ukuma njengesikwele noma umbuthano. Naphezu kokuhleleka kwebhokisi lokukwakha i-vector, izindlela zingasetshenziswa ukwakha imidwebo enzima kakhulu. Into ngayinye yezinyawo ithatha isitatimende sayo sembalo esichaza indlela into okufanele ikhonjiswe ngayo. Amanye amafomethi we-vector avamile afaka i-AI (Adobe Illustrator), i-DXF (i-AutoCAD DXF), ne-CGM (i-Computer Graphics Metafile) .Ihluzo zeVector zingatholakala nasefomethi ye-EPS (Encapsulated PostScript) ne-PDF (Portable Document Format).
Umehluko obaluleke kunazo zonke phakathi kwehlukumezi ze-vector ne-bitmap yilokho ihluzo ze-vector ziyizixazululo ezizimele, okusho ukuthi zishayekile ngempela. Ngenxa yokuthi ihluzo ze-vector azihlanganiswa negridi ehleliwe njengehluzo ze-bitmap, zingahle zishintshwe kabusha ngaphandle kokulahlekelwa ikhwalithi yesithombe. Lokhu kubenza kube kuhle ezinhlelweni ezihlukahlukene zokudweba ezinjenge-logos, ezidinga ikhono lokunciphisa phansi into encane njengekhadi lebhizinisi noma ukuphakanyiswa okuthile okufana nephawu lwebhodibhodi.
Vector Izithombe Basics
Ngenkathi abanye abahleli be-vector (izinhlelo zekhompyutha ezakha futhi zihlela ihluzo ze-vector) izithombe zokusekela, izinhlelo ezidumile kakhulu zokudala izithombe, njenge-Adobe Flash, zihloselwe ngokuqondile leyo njongo. Ngenkathi izithombe zingabandakanya ihluzo ze-bitmap, iningi lisebenzisa ihluzo kuphela ezisuselwa ku-vector ngoba njengoba sifundile ngaphambili, ziba ngcono futhi zithatha isikhala esincane. Lezi zithombe ze-vector ngokuvamile zibonakala zibukeka ngokucacile uma ziqhathaniswa nezinye izindlela zazo.
Ngaphakathi kwezwe, kunezinye izakhiwo ze-vector nama- animators . Isibonelo, i-EVA (i-Extended Vector Animation) ifomethi yefayela ye-vector efomethiwe e-Japan lapho isofthiwe ye-EVA Animator isetshenziswa kakhulu. Umehluko omkhulu phakathi kwefomethi ye-EVA namanye amafomethi e-vector ukuthi arekhoda kuphela izinguquko ku-vector ngokuhamba kwesikhathi esikhundleni sokurekhoda ulwazi ngolwazi ngalunye. Izakhiwo ze-EVA nazo zivame ukuba zincane kunezinye izindlela zazo.
