Kev ua qauv yog kev lom zem-kom txog thaum koj pom koj tus kheej nce tawm tsam ntawm ib lub pob cib ntawm kev phem topology , cov ntsej muag uas tsis yog neeg ua haujlwm, sab nrauv, thiab ib pawg tseem ceeb ntawm cov teeb meem uas koj tsis paub daws teeb meem li cas.
Hauv daim ntawv teev npe no, peb pom cov cuab tsib caug uas pib hloov cov qauv feem ntau poob qis. Yog tias koj nyob nraum tshiab rau cov qauv zoo nkauj ntawm cov qauv 3D , nyeem kom koj txuag tau koj tus kheej ntawm ib lossis ob lub taub hau tom qab ntawm txoj kev.

Tawm Ambitous, Too Tsis ntev
Ambition yog qhov zoo. Nws yog dab tsi ua rau peb siv zog ua tej yam loj thiab zoo dua, nws nyuaj rau peb, ua rau peb zoo dua. Tab sis, yog tias koj xav tias koj yuav dhia mus rau hauv ib lub qauv ntawm cov qauv 3D thiab tsim ib tus qauv ntawm qhov tsis tshua muaj qhov nyuaj rau koj thawj zaug, koj yuav raug yuam kev.
Nws yog kev ntxias tsom rau cov hnub qub sab nraud ntawm lub rooj vag, tab sis yog vim li cas koj pom kaum ob ntawm cov kev hloov ntawm cov nram qab no quote feem ntau ntawm CG cov rooj sab laj: "Qhov no yog ib daim duab uas kuv tau muaj nyob rau hauv kuv lub taub hau rau xyoo, tab sis kuv 'peb tau tos kuv cov kev txawj ntse kom ntes tau. "
CG yog ib qho nyuaj, nws yog technical thiab complex. Thaum koj npaj koj cov dej num los nug koj tus kheej, "Kuv yuav ua li cas cov kev ua rau kuv xav tau, thiab kuv tuaj yeem kho tau lawv lub sijhawm no?" Yog tias cov lus teb yog muaj, mus rau nws! Txawm li cas los xij, yog tias tus txheej txheem xa ntawv tuaj yeem xav kom koj sim cov plaub hau, dej dawb, thoob ntiaj teb illumination, thiab kev xeem dhau rau thawj zaug, nws muaj peev xwm smarter los kawm txhua lub ntsiab lus ntawm tus kheej ua ntej koj sim muab lawv ua duab. Tawm koj tus kheej, tab sis sim paub thaum twg koj ambition tau txais qhov zoo ntawm koj.
Tsis paub tseeb, ntau tshaj li lwm yam, yog dab tsi ua rau cov kev tsim tso tseg, thiab nyob rau hauv kuv lub tswv yim, tus duab tsis zoo yog tseem zoo dua ib qho tsis tiav.

Kev tsis lees paub Topology
Topology thiab ntug ntws tseem ceeb heev rau cov qauv ua cim uas txhais tau hais tias yog kev ua kom muaj cov animation. Rau cov kev ua si zoo li qub-qhov chaw, thiab ib puag ncig cov qauv, ntug ntws zoo dua, tab sis qhov ntawd tsis txhais hais tias nws yuav tsum raug ignored nkaus.
Cov qauv hauv quads (plaub-sided polygons) ntau npaum li ua tau, tshwj xeeb tshaj yog tias koj npaj rau kev coj tus qauv rau hauv Zbrush los yog Mudbox rau tom sculpting tom qab. Quads zoo tagnrho vim hais tias lawv muaj peev xwm muab subdivided (rau sculpting) los yog triangulated (rau kev ua si-xyaw) yooj yim heev thiab yooj yim.
Topology yog lub ntsiab lus loj heev, thiab mus rau hauv kev nthuav dav ntawm no yuav tsis yooj yim sua. Cia li khaws qee cov hauv paus ntsiab lus thaum koj ua haujlwm:
- Tsis txhob N-gons (5-sided polygons lossis greater).
- Khaws daim duab peb sab rau ib tus txheeb ze.
- Sim ua kom muaj kev sib koom ua ke, thiab tsis txhob txhawj ntsej muag. Koj cov duab tsis tas yuav tsum yog xwm txheej zoo tiam sis cia lawv nyob ze rau qhov uas koj tuaj yeem tsim nyog.
- Rau ib qho mesh animated, ntxiv cov ntug looj ntxiv rau txhua qhov chaw yuav muaj deformation (lauj tshib, hauv caug, di ncauj, thiab lwm yam).
- Nco ntsoov ntxuav cov khoom thaij sab saum toj tom qab siv Maya's bevel tool (uas feem ntau tsim cov vaj tse peb sab thiab qee zaus n-gons.
- Yog hais tias koj du koj tus qauv thiab daim ntawv ceeb toom "pinching" sim xav txog seb koj tuaj yeem rov tau txoj hauv kev kom koj lub ntsej muag zoo zoo dua.
- Yog tias koj pom tias tsis muaj tus qauv ntsuas (geometry) , nres qhov koj tab tom ua thiab kho tam sim ntawd . Yog tias koj tsis paub meej hais tias tsis yog tus txiv neej tus qauv, nws nyem qhov no .

Ntau Hlis, Nyuam Ntxov
Yog hais tias kuv nco ntsoov hais kom yog, qhov no yog ib yam uas peb tau kov rau hauv peb feem ntau ntawm tus nplaig-hauv-cheek Yuav ua li cas ua phem CG tsab xov xwm , tab sis nws fits ntawm no zoo li.
Tshaj tawm ntawm koj lub ntsej muag thaum ntxov ntawm kev ua tus qauv yuav tsuas ua rau mob thiab kev tu siab, thiab feem ntau tuaj yeem ua rau "lumpy" los sis tsis pom zoo zoo hauv ntau ntau yam haujlwm tshiab.
Raws li txoj cai ntawm tus ntiv tes xoo, tsis txhob ntxiv qhov kev daws teeb meem kom txog rau thaum koj paub tseeb tias koj tau ntov cov duab thiab silhouette nrog cov uas koj twb muaj lawm. Yog tias koj pom koj tus kheej hauv ib qho xwm txheej uas koj xav tau hloov tag nrho cov qauv ntawm koj tus qauv tab sis twb subdivided rau ib tug taw tes uas koj tsis tau ua nws zoo, sim siv lub cuab yeej lattice hauv Maya's animation zaub mov. Yog tias koj pib hnov cov lus tsis zoo rau ntawm koj tus qauv, sim siv lub txhuam kom zoo rau lub lumps.

Txhua zaus Ua Qauv Ua Seamless Meshes
Nws yog ib qho kev tsis sib haum xeeb ntawm cov pib qauv tias ib tus qauv tiav lawm yuav tsum yog ib qho kev tsis sib haum xeeb nkaus xwb. Qhov no tsis yog qhov teeb meem txhua lub sij hawm, thiab sim ua cov qauv uas yuav ua rau koj lub neej nyuab dua.
Kuv nco ntsoov saib 3DMotive kev cob qhia ua ke ib ntus rov qab thiab tus kws qhia muaj ib txoj hauv kev zoo los xav txog cov nqe lus nug ntawm seb lub hauv paus ntawm koj tus qauv yuav tsum yog tsis ua hauj lwm los yog cais geometry; xav txog txoj kev tus qauv koj nyob nraum tsev yuav raug tsim ua hauv lub ntiaj teb tiag, thiab sim nws kom ze rau qhov ua tau.
Cov neeg tsim khoom pheej hais tias daim ntawv ua raws li nram qab no, thiab daim ntawv qhia tau tuav qee qhov ceeb thawj ntawm no-yog tias koj khiav mus rau qhov chaw uas koj xav tias nws yuav yooj yim rau cov qauv hauv ob daim ntawv, ua nws.
Tam sim no nws tau hais tias, muaj ob qho kev zam rau qhov no- 3d luam , thiab kev ua si kos duab.
3D luam tawm nrog cov txheej txheem tseem tshiab, tias peb yuav tsis nkag mus rau hauv no, tab sis, yog tias koj xav tau peb tau sau ib daim ntawv qhia luv luv rau ntawm qhov teeb meem. Nrog kev ua si nraaj, nws yog qhov feem ntau nyiam rau qhov khoom vaj khoom zaum kawg yuav yog ib qho seamless mesh, Txawm li cas los, qhov kev ua si zaum kawg mas feem ntau yog ib tug retopologized version ntawm ib lub high-resolution mesh. Yog hais tias tsis muaj kev txiav txim siab, tsis txhob fret-tus tom ntej gen gameart workflow yog heev technical thiab txoj kev tshaj li qhov ntawm Scope ntawm no tsab xov xwm, txawm li ntawd los, lub aforementioned 3DMotive nyeem (Cov khoom muaj nqis Chest series) npog nws zoo heev.
Rau tam sim no, nyuam qhuav paub, nws zoo heev los siv ntau yam khoom los ua kom tiav ib qho qauv siab kawg.

Tsis siv duab Planes
Kuv paub qhov no zoo vim tias kuv siv los sim muag khoom txhua lub sijhawm, los yog dhia mus rau hauv Maya yam tsis xav xaiv thiab kev hloov ua ke, xav "huag kuv mam li tsim nws raws li kuv sim qauv nws."
Kuv maj mam tsim ib qhov cwj pwm ntawm kev nqa me ntsis 5 los ntawm 7 pad ntawm daim phiaj ntawv, thiab thaum twg kuv tsis ua dab tsi Kuv yuav rub tawm ib phab thiab kos tawm tswv yim tawm tswv yim rau cov tuam tsev thiab cov khoom muaj nqi. Kuv muab pov tseg ob zaug ntau npaum li kuv txuag tau, tab sis yog tias kuv nyiam ib qho kuv mam li muab nws tso rau ntawm ib co corkboard saum kuv tus saib kom nws nyob ntawd yog tias kuv puas xav tau nws. Yog tias kuv txiav txim siab ib qho ntawm lawv mus rau hauv ib qhov project, kuv mam li ua ib lub luam theej duab thiab rub nws mus rau hauv Maya ua duab dav hlau.
Tsis yog nws cia kuv ua hauj lwm sai, nws tso cai rau kuv mus ua hauj lwm ntau dua, thiab qhov tseeb yog ib qho yuam sij rau kev ua haujlwm. Tam sim no kuv siv cov duab dav hlau rau txhua qhov khoom vaj khoom tsev uas kuv tau hloov, tshwj xeeb tshaj yog cov cim los yog tej lub pob zeb loj, thiab kuv txoj haujlwm yog qhov zoo dua rau nws.
Thiab qhov no suav ob zaug (lossis txawm triple) yog tias koj nyob nraum shooting photorealism!
Yog li tam sim no koj paub dab tsi yuav tsum tsis txhob!
Txhua tus thiab peb txhua tus tau ua txhaum ntawm qee yam lossis tag nrho cov khoom no ib zaug los yog lwm qhov.
Ua yuam kev yog qhov tseem ceeb ntawm txoj kev kawm, tiam sis nws yog peb txoj kev cia siab tias los ntawm kev paub txog qee tus ciav hlau uas ua rau tus neeg pib mob plague rau kev ua qauv zoo , koj yuav muaj peev xwm zam tau koj tus kheej.
Zoo siab ua qauv!
