Ngemva kweminyaka emine yentuthuko ukukhululwa kwephakheji , ehlanganisa umhleli wezithombe zevekhtha kanye nesistimu yokudala ukugqwayiza kwe-2D. Uhlelo lubekwe njengephrojekthi yocwaningo enokuqaliswa kokuhlolwa komqondo wezibalo (I-Vector Graphics Complex), ekuvumela ukuthi udale izithombe ezinyakazayo nemifanekiso engaboshelwe ekulungisweni kwamaphikseli. Intuthuko yephrojekthi ibhalwe ku-C++ (kusetshenziswa i-Qt ne ) Futhi ilayisensi ngaphansi kwe-Apache 2.0. Izakhiwo ezilungiselelwe i-Linux (), iWindows ne-macOS.
Ingqikithi yendlela ye-VGC ukwenza ngokuzenzakalelayo ukulandela ngomkhondo kokuxhumana phakathi kwemigqa kumdwebo we-vector, okwenza inqubo yokuhlela ibe lula ngokwenza lula ukucutshungulwa komumo abanemingcele efanayo. Ngokuvamile, amajika akha imingcele ethintayo yomumo ababili adwetshwa ngokuhlukana (ijika elihlukile lidwetshwa umumo ngamunye). Ku-VPaint, umngcele uchazwa kanye bese unamathiselwa kumumo ngamunye futhi ungahlelwa kanye nawo. Opopayi “njenge-spatio-temporal topological complex” lapho imingcele ehlangene ehambisanayo yomumo ivumela ukuhlukana okuyinkimbinkimbi noma ukuhlangana komumo ukuthi kwenzeke, futhi kusizakale ukukhiqizwa okuzenzakalelayo kwamafreyimu amaphakathi.
Uhlelo lusesigabeni se-prototype ngekhwalithi yokukhishwa kwe-beta, luhlinzeka kuphela ngohlaka lwamathambo oluyisisekelo lwemisebenzi eyinhloko ukuze kuhlolwe umqondo wokuhlela ohlongozwayo kanye nomdwebi wezithombe ezingafanelekile umsebenzi wansuku zonke. Nokho, i-VPaint ithola ukusebenza kancane kancane futhi inguqulo entsha manje ihlanganisa ukusekelwa kwezendlalelo, ukungenisa amafayela e-SVG nokusekelwa kwezikrini eziphezulu ze-pixel (HiDPI).
Ngokuzayo, ukuthuthukiswa kwe-VPaint kuhlelwe ukuthi kusetshenziselwe ukudala amaphakheji okuthengisa . Eyokuqala ihloselwe ukuncintisana namaphakheji e-Adobe Illustrator, Autodesk Graphic, CorelDRAW kanye ne-Inkscape, kanti eyesibili ne-Adobe Animate, ToonBoom Harmony, CACANi, Synfig ne-OpenToonz.
Womabili amaphakheji, ngaphandle kokusatshalaliswa okukhokhelwayo, azonikezwa njengomthombo ovulekile ngaphansi kwelayisensi ye-Apache 2.0. I-Builds ye-Linux izolethwa mahhala (kuphela izinhlelo ze-Windows ne-macOS ezizokhokhwa).
Izici eziyinhloko:
- Amathuluzi okudala imidwebo yefomu lamahhala. Esikhundleni samajika
Imigqa yezier eyakha umfanekiso yakhiwe njengamajika adwetshwe ngesandla abizwa ngokuthi "umphetho". Amajika angaba yinoma yikuphi ukujiya futhi ngokuvamile asethwa kusetshenziswa ithebhulethi. - Amathuba okumodela okuqoshiwe. "Amaphethelo" adwetshiwe
ingahlelwa ngesitayela ngezinguquko ezingahleliwe kububanzi bejika, ububanzi nezinga lokushelela. Imihlukanandlela nama-tangent wamajika alandelelwa ngokuzenzakalelayo futhi alondolozwe ngesikhathi sokuhlela, ngokungafani nabahleli bakudala lapho amajika
Amajika e-Bezier aphathwa njengamajika azimele. - Ithuluzi lokugcwalisa elikuvumela ukuthi uguqule umbala wohlaka ngokuchofoza nje endaweni eboshwe imiphetho. Ngokungafani nabanye abahleli be-vector abaningi, lapho ugcwalisa, imiphetho eyakha umngcele ilandelwa, futhi ngokuzayo, lapho uhlela le miphetho, indawo egcwele umbala ibuyekezwa ngokuzenzakalelayo, futhi konke ukuxhumeka konqenqemeni kugcinwa.
- I-Timeline Animation, enikezela ngesixhumi esibonakalayo esilula sokudala ukugqwayiza kohlaka ngohlaka. Ungadweba uhlaka, bese ulukopisha futhi wenze izinguquko kuhlaka olulandelayo, njll. Umsebenzi wokunamathisela onyakazayo uyatholakala, okukuvumela ukuthi ufake izakhi ezijwayelekile kumafreyimu ambalwa ngesikhathi esisodwa ngokwakheka okuzenzakalelayo kwamafreyimu amaphakathi.
- Ukwemba u-anyanisi, okukuvumela ukuthi umboze amafreyimu amaningana ancikene ngesikhathi esisodwa ukuze uthuthukise ukulawula isikhathi kanye ne-trajectory yokugqwayiza. Ungakwazi futhi ukuhlukanisa indawo ebonakalayo ezindaweni eziningi ukuze ubuke noma uhlele ozimele abahlukene ngesikhathi esisodwa.
