Mu makina a makompyuta , pamene wojambula amatha kumanga chikhalidwe, ndi maimidwe a 3D omwe amawoneka ngati maonekedwe a marble. (Ndipo ngati munayamba mwayesa kujambula ndi kujambula zithunzi zamatabwa, mumadziŵa kuti zimakhala pafupi ndi zosatheka).
Pambuyo pachitsanzo cha 3D character akhoza kuperekedwa ku gulu la animators, ziyenera kukhala zomangamanga ndi zida zothandizira kuti otsogolera athe kupanga chitsanzo. Ntchitoyi imatsirizidwa ndi ojambula omwe amadziwika ngati otsogolera otsogolera (TDs) kapena ovina.
Khalidwe la TDs limagwirira ntchito limodzi ndi owonetsera kuti zitsimikizidwe zazomwe zimakambidwa, koma ntchito yawo yayikulu ndi kutenga maimidwe a 3D omwe amachititsa kukonzekera zojambulazo-ndondomeko yotchedwa kukola.
Kugwedeza
Chigoba choyimira chimakhala mafupa adijito omwe amamangidwa ku meshiti ya 3D. Monga mafupa enieni, thumba limapangidwa ndi mafupa ndi mafupa, zomwe zimakhala ngati "kugwiritsira ntchito" zomwe ozilitsa angagwiritse ntchito kuti azigwedeza khalidwelo ku zofunikanso.
Chikhalidwe chokha chingakhale chophweka ndi chokongola kuti chikhale chovuta kwambiri. Chida chokhazikika chosavuta chingamangidwe m'maola ochepa, pamene ndondomeko yowonjezera ya filimuyo ingafunike masiku kapena masabata asanayambe kukonzekera mafilimu a Pixar.
Kuyika Skeleton
Kuyika kwa mafupa mwina ndi gawo lophweka kwambiri pazitsulo. Kawirikawiri, ziwalo ziyenera kuikidwa pamalo enieni kumene zikanakhala mu mafupa enieni, ndi zosiyana kapena ziwiri.
- Otsogolera Otsogolera: Pofuna kugwira ntchito bwino, mafupa ndi ziwalo ziyenera kutsatizana ndi ndondomeko yoyendetsera bwino. Mukakhazikitsa mafupa a munthu, choyamba chokhalapo chimatchedwa mzere wothandizira . Mgwirizano uliwonse wotsatira udzakhudzana ndi muzu kaya mwachindunji, kapena mwachindunji kupyolera mu mgwirizano wina.
- Kupititsa patsogolo Kinematics: Kupititsa patsogolo kumbuyo (FK) ndi imodzi mwa njira ziwiri zofunika kuwerengera kayendetsedwe ka chiyanjano chokwanira. Pogwiritsira ntchito FK mbolo, mgwirizano uliwonse ukhoza kukhudza zigawo zina za mafupa omwe amagwera m'munsimu pazowonongeka.
- Mwachitsanzo, kusinthasintha kwa mbali ya chikhalidwe kumasintha malo a goli, mkono, ndi dzanja. Poyimba ndi zakulumikizidwe zamtsogolo, wojambulayo amafunika kuyendetsa mpikisano ndi udindo wa gulu limodzi payekha-kuti akwaniritse zofunikanso pamene wotsogolera amatha kugwira ntchito mwadongosolo lotsogolera sequentially: mizu → msana → m'mphepete → chikhomo → etc. Malo otsiriza Kuphatikizira (ngati mphuno) kumawerengedwa ngati ntchito ya mazenera ophatikizana a mgwirizano uliwonse pamwamba pa iyo mu ulamuliro.
Zinenero Zachilengedwe
IK kugwiritsira ntchito ndi njira yotsutsana ndi zakuthambo ndipo nthawi zambiri imagwiritsidwa ntchito njira yothetsera kugunda kwa manja ndi miyendo ya munthu. Pogwiritsa ntchito IK, mgwirizano wotsekedwawo umayikidwa mwachindunji ndi wotsogolera, pomwe ziwalozo pamwamba pake pazitsogoleredwe zimangotchulidwa ndi software.
IK ndi yoyenera kwambiri pamene zojambulazo zimafuna kuti mgwirizano ukathe kuikidwa bwino kwambiri & $ 151; munthu wokwera makwerero ndi chitsanzo chabwino. Chifukwa chakuti manja ndi miyendo ya munthuyo imatha kuikidwa mwachindunji pamakwerero a makwerero m'malo mowongolera kuti azisintha malo awo ophatikizana nawo, chigamulo cha IK chingachititse kuti zithunzithunzi zikhale bwino kwambiri. Chotsatira chimodzi ndichoti chifukwa mafilimu a IK amagwiritsa ntchito mapulogalamu a mapulogalamu, nthawi zambiri pamakhala ntchito yowonongeka yomwe iyenera kuchitidwa pofuna kuthetsa kuwombera.
Malamulo a Ufulu / Zotsutsana
Pamene mukugwedeza, kumbukirani kuti malemba monga mabala ndi mawondo amatha kukhala ndi chiwerengero chimodzi cha ufulu mudziko lenileni, kutanthauza kuti akhoza kugwedeza limodzi limodzi. Mofananamo, khosi la munthu silingasinthe madigiri 360. Pofuna kuthana ndi zosayembekezereka, ndibwino kukonza zovuta pamene mukukumanga. Tidzakambirana zambiri pa phunziroli.
Sikwashi ndi Kudula
Kuganiziranso kwina koyenera kupangidwa ndi ngati ngongole idzawathandiza squash ndi kutambasula, kapena ngati khalidwelo lidzakakamizidwa kuti liziyenda bwino. Sikwashi ndi kutambasula ndi mfundo yofunikira pa zojambula zojambula zojambulajambula , koma kawirikawiri siziwoneka bwino mu kanema / VFX. Ngati mukufuna kuti muteteze kuti mukhale osakwanira, ndikofunika kukhazikitsa zovuta kuti mutseke malo a mgwirizano uliwonse poyerekeza ndi zina zonse.
Kuthamanga kwa nkhope
Khungu la nkhope la munthu limakhala losiyana kwambiri ndi kayendetsedwe ka kayendetsedwe kake. Ndizovuta ndipo zimakhala zovuta kwambiri kuti zitheke kugwiritsira ntchito mwambo wokhudzana ndi chikhalidwe / mafupa, kotero kuti zovuta za morph (kapena kuphatikiza mawonekedwe) zimawoneka ngati njira yowonjezera. Kugwiritsira nkhope pamutu ndi nkhani yake yokha, kotero yang'anani nkhani ikufufuzira nkhaniyo mozama.
