Yuav Paub
- Yuav tsum paub: keeb kwm hauv 2D kos duab tsis tsim nyog rau 3D, tab sis nws tuaj yeem txhawb kev txawj 3D.
- Tsom rau: Kev nrawm nrawm / thumbnail iteration. Kev xav. Compositing/set extension/matte painting. Composition.
- Tsis txhob tsom rau: Pom-pom daim duab (kos duab raws nraim li koj pom), lossis tsim-zoo digital painting / 2D rendering.
Kab lus no piav qhia qee qhov feem ntau (thiab tsawg kawg) siv tau 2D kev kos duab rau siv hauv 3D qauv.
Kuv Yuav Tsum Paub Yuav Kos Rau 3D?
Txawm tias tsis tsim nyog, lub hauv paus tsim tau zoo hauv cov duab kos duab lossis cov duab kos duab digital yog ib qho cuab yeej tseem ceeb ntawm txoj kev mus rau kev vam meej raws li tus kws kos duab 3D.
Muaj ntau yam rau qhov no. Kev kos duab ua rau koj muaj ntau yam. Lawv muab kev yooj yim thiab kev ywj pheej rau koj thaum pib tsim cov theem. Lawv muab koj lub peev xwm los sib xyaw ua ke 2D thiab 3D cov ntsiab lus. Lawv tso cai rau koj los tweak koj cov duab hauv kev tsim khoom tom qab los txhim kho cov txiaj ntsig koj tau txais los ntawm koj lub cav ua haujlwm. Tsis muaj lus nug tias kev txawj 2D ib txwm muaj txiaj ntsig zoo rau txhua tus kws kos duab 3D.
Rau cov tub ntxhais hluas ua yeeb yam hauv tsev kawm theem nrab lossis tsev kawm theem siab, nws yuav tsim nyog siv sijhawm thiab siv zog los tsim 2D kev txawj kos duab. Txhua tus kws kos duab cov ntaub ntawv yuav tau txais txiaj ntsig los ntawm cov txheej txheem dav dav, suav nrog kev kos duab, kos duab, 3D qauv, texturing, thiab rendering.
Tab sis ua li cas yog tias koj coj mus rau 3D tom qab hauv lub neej thiab tsis muaj sijhawm los kawm kos duab lossis pleev xim? Puas yog nws zoo dua los tsom tag nrho rau 3D, lossis ua ib kauj ruam rov qab thiab txhim kho lub hauv paus ruaj khov hauv 2D?
Qhov tseeb yog nws nyob ntawm koj qib kev txawj thiab cov peev txheej. Ntawm no peb saib qee qhov kev txawj ntse tshaj plaws thiab tseem ceeb tshaj plaws rau kev kawm 2D thiab 3D kev kos duab thiab ua kom pom.
2D Kev Txawj Ntse Koj Yuav Tsum Ua Rau
Yog tias koj tau txiav txim siab siv sijhawm sijhawm los kawm 2D, ntawm no yog qee qhov kev txawj thiab cov tswv yim uas yuav ua pov thawj muaj txiaj ntsig zoo rau ib tus neeg xav pib ua haujlwm hauv 3D computer graphics:
- Sketching and Thumbnail Iteration: Lub peev xwm ua kom nrawm nrawm ntawm lub tswv yim los ntawm sketches thiab thumbnails yog lub peev xwm muaj txiaj ntsig ntau. Yog tias koj tuaj yeem churn tawm kaum lossis kaum tsib tus duab me me hauv ob peb teev, nws ua rau koj nyob hauv txoj haujlwm zoo. Koj tuaj yeem qhia lawv rau cov phooj ywg thiab tsev neeg, lossis hauv CG cov rooj sib tham kom paub seb qhov twg ua haujlwm thiab qhov twg tsis ua. Koj tseem yuav muaj kev ywj pheej los muab cov tswv yim los ntawm ntau cov duab kos los tsim koj tus qauv kawg.
- Perspective: 3D software yuav tuaj yeem ua qhov kev xav tau, tab sis qhov ntawd tsis cuam tshuam tus nqi ntawm kev nkag siab qhov kev xav rau ob qho tib si 2D thiab 3D kos duab. Xav tias nws yog ib lub hauv paus txheej txheem ntawm txhua yam tsim.
- Kev sib sau. Teeb Extension. Matte Painting: Cov no yog tag nrho cov ntsej muag ntawm CG uas nyob ntawm qhov sib xyaw ua ke ntawm 2D thiab 3D cov ntsiab lus. Rau ib daim duab kawg kom ua tiav yuav tsum muaj qhov kev pom meej meej txuas ntxiv. Hauv qee qhov xwm txheej, koj yuav tsis muaj sijhawm los ua qauv tag nrho hauv 3D. Thaum lub sijhawm ntawd los, koj yuav zoo siab tias koj paub yuav ua li cas tso 2D cov ntsiab lus rau ntawm daim phiaj kev pom tseeb.
- Composition: Ib puag ncig zoo lossis tsim tus cwj pwm tuaj yeem sawv ntawm nws tus kheej, tab sis cov ntsiab lus saum toj kawg nkaus feem ntau yog qhov cais cov duab zoo ntawm cov duab zoo xwb. Lub qhov muag rau kev muaj pes tsawg leeg yog ib yam dab tsi uas yuav txhim kho organically nyob rau lub sijhawm, tab sis nws tsim nyog los khaws ib phau ntawv lossis ob qho ntawm qhov kev kawm. Ua tib zoo saib rau cov phau ntawv ntawm zaj dab neeg-boarding, uas tuaj yeem yog ib qho chaw zoo heev rau ob qho tib si hauv kev sau thiab xoob kos duab.
Techniques Yuav Tsis Tsim Nyog Koj Lub Sijhawm
- Sight-See Drawing: Pom-pom yog hais txog cov txheej txheem ntawm kev kos duab raws nraim qhov koj pom. Nws yog cov txheej txheem kev kos duab nyiam nyob rau hauv ntau qhov chaw atelier thiab yog ib qho kev txawj ntse uas muaj txiaj ntsig yog tias cov duab kos duab thiab kos duab yog lub hom phiaj tseem ceeb. Tab sis rau ib tus neeg sim txhawb lawv cov txuj ci kev kos duab yooj yim los txhim kho raws li tus kws kos duab 3D, pom-pom kos duab yog tus nqi me me. Los ntawm nws qhov xwm txheej, pom-pom yog tag nrho ntawm cov qauv nyob thiab cov ntaub ntawv tseeb. Raws li tus kws kos duab CG, koj yuav tsim cov khoom uas tsis muaj nyob hauv lub ntiaj teb tiag tiag - cov tsiaj tshwj xeeb, ib puag ncig kev xav, dab neeg, cov cim, thiab lwm yam. Kev kawm ua cov ntawv luam ntawm cov duab siv yuav pab ntxiv qee qhov kev muaj tiag rau koj cov demo reel, tab sis nws yuav tsis qhia koj yuav ua li cas los tsim koj tus kheej.
- Production-Quality Digital Painting/2D Rendering: Yog tias koj lub hom phiaj tseem ceeb yog ua haujlwm hauv 3D, qhov txawv yog qhov zoo koj yuav tsis tas yuav kho cov duab kos lossis duab me me rau hauv ib tug ntau lawm-theem daim ntawm artwork. Nws yuav siv sij hawm ntau xyoo los kawm txog kev pleev xim lub teeb thiab duab ntxoov ntxoo, ua daim ntawv, thiab nthuav dav ntawm qib kev tshaj lij. Tsis txhob cia siab tias yuav kawm yuav ua li cas pleev xim zoo li Dave Rapoza, thiab tom qab ntawd nrhiav koj txoj haujlwm 3D. Nws yuav siv sij hawm ntau xyoo thiab ntau xyoo kom mus txog qib ntawd, thiab ntau tus neeg yeej tsis ua nws lawm. Tshwj tsis yog lub tswv yim-kos duab yog qhov koj xav ua haujlwm tshaj lij, koj zoo dua los tsom rau tej yam uas yuav pab tau koj ua tiav koj lub hom phiaj ntawm tus kheej. Koj yeej tsis xav kis koj tus kheej kom nyias nyias ntawm kev pheej hmoo ntawm kev poob siab.
Yuav ua li cas txog Anatomy?
Peb tsis tuaj yeem ua siab zoo pom zoo tawm tsam kev kawm kos tib neeg lub cev. Yog tias koj npaj yuav ua tus ua yeeb yam ua yeeb yam, koj yuav tsum kawm qee qhov kev xav ntawm lub cev. Tau hais tias, nws puas yuav muaj txiaj ntsig zoo dua los kawm kev kho lub cev ncaj qha hauv Zbrush, Mudbox, lossis Sculptris?
Muscle nco ua lub luag haujlwm loj hauv kev kos duab, thiab txawm tias muaj qee qhov sib tshooj ntawm kev kos duab ntawm daim ntawv thiab sculpting digitally, ib tus yuav tsis hais tias lawv zoo ib yam. Vim li cas siv ntau pua teev kom ua tiav cov duab kos duab kos duab thaum koj tuaj yeem siv sijhawm los txhawb koj lub peev xwm sculpting?
Peb tsis xav sib cav tawm tsam kev kawm lub cev los ntawm kev kos duab, tab sis qhov tseeb yog, kos duab hauv ZBrush tau mus txog qhov uas nws tsis tshua qeeb dua li kos duab rau ntawm daim ntawv. Peb xav tias yog ib yam uas tsim nyog xav txog. Koj tseem tuaj yeem kawm Loomis, Bammes, lossis Bridgman, tab sis vim li cas ho tsis ua 3D?
