Nzira Dzakanaka Dzichaita Kuti 3D yako Ipe Zvimwe Zvimwe Zvechokwadi
Photo-realism ndeimwe yezvinangwa zvevakawanda veCG artists, uye ndeimwe yezvinonyanya kuoma kubudirira. Kunyange kana iwe uri mutsva ku 3D mifananidzo yemafuta , zvisinei, zvishandiso zvemazuva ano uye mashizha ekufambisa kwebasa zvinogadzira kuitika kwemafoto kunowanikwa. Heano maitiro masere okukubatsira kuti uende ikoko:

Bevel, Bevel, Bevel
Kukanganwa kuvekwe kana kuti kukwikwidza kumativi ndeimwe yezvikanganiso zvakakurumbira zvakaitwa nevatangi vema 3D. Icho chiri pedyo nehuse-yakakorokera kumativi emasikirwo, uye kunyange zvinhu zvakawanda zvakagadzirwa nevanhu zvinotenderera zvishoma apo nzvimbo mbiri dzinopikisana dzinosangana. Kunyanya kubetsera kunobatsira kuburitsa zvakadzama, uye kunotengesa zvisizvo zvemuenzaniso wako nekubvumira mitsetse kuti iwane zvakakosha kubva pakuchenesa kwako.
Kushandisa bevel (kana chamfer tool mu 3ds Max) ndeimwe yezvinhu zvokutanga zvaunofanira kudzidza semuenzaniso. Kana uri musha wakakwana kusvika kuD 3D kuti hauna chokwadi kuti iwe ungagadzira sei mapepa, iwe mukana unogona kubatsirwa zvechokwadi kubva mudzidzo yakanaka yekutanga kana kunyange kubhadharo yekudzidzira .

Dzidza Kushandisa Linear Workflow
Kunyange zvazvo kushandiswa kwemaitiro kwakapoteredza kwemakore, ichiri chikonzero chinokanganisika uye chakaoma kune vanotanga. Handizoedza kuitsanangurira zvakakwana dzidziso iyi (pane zvakawanda zvokutaura), asi ndinoda kuve nechokwadi kuti iwe unenge uchiziva kuti maitiro aya aripo.
Chido chekushanda kwemazuva ano chinowanzosvika pakuti chokwadi chako chinoratidza mifananidzo mune imwe nzvimbo yemuvara (sRGB) pane izvo zvinobudiswa nejini yako (linear). Kuti urwise izvi, vanyori vanofanirwa kutora matanho anodiwa ekushandisa gadzirudzo yekugadzirisa kuti iite.
Asi basa rakasununguka rinonyatsoenda kune zvisingasarudze gamma zvigadziriswe-zvinenge zvese nezvekuchera maitiro ekare uye mabasa (akawanda ayo anowanikwa pane nguva dzisina nguva), uye achienda kune chokwadi chechokwadi chekugadzirisa mhinduro.
Kune zvakawanda zvakawanda zvokutaura pamusoro pekushanda kwemashoko, nekuonga zvakambokurukurwa zvakanyanya mumakore mashoma akapfuura. Heino chibatsiro chakakosha chekudzidza nheyo yekusangana-anonongedzera kune dzimwe nzvimbo zvishoma, saka pane zvakawanda zvekuverenga zvinofanira kuitwa. Chechipiri inosungirirwa ndeye Digital Tutors course iyo inobata zvakananga nekushanda kwemashoko muMaya 2012.

Shandisa IES Light Profiles yePhotometric Lighting
Pamwe chete nekukwira kwebasa rekushanda, 3D artists (kunyanya avo vanoshanda mukugadzira zvigadzirwa) vakatanga kushandisa mafaira anonzi IES chiedza mapairi kuitira kuti vanyatsofananidza mhepo chaiyo-chiedza chenyika.
Nhoroondo dzeIES dzakanga dzakasikwa nevakagadziri vakaita seGener Electric senzira yekuita digital kuverenga photometric lighting data. Nokuti IES inojekesa zvinyorwa zvine chinyorwa chakarurama photometric pamusoro pekugadzirwa kwechiedza, kubwinya, uye kumira. Vashandi ve 3D vakawana mukana wekuwedzera IES kutsigire mune dzakawanda zvikuru 3D mapuraneti.
Nei uchipedza maawa uchiedza kuenzanisa chiedza chenyika chaiyo apo iwe unogona kushandisa nhoroondo yeIES uye une chinhu chaicho?
CG Arena ane chinyorwa chakanaka nemamwe mapikicha makuru kukupa pfungwa yekuti IES inoratidzi yekunaka yakaita sei.

Shandisa Kureba Kwemunda
Kudzika kwebindu (zvakasvibiswa kumashure) migumisiro ndeimwe yenzira dzakanyanyisa dzekuwedzera huripo hwekushandura kwako nokuti chinhu chatinoshamwaridzana nehupenyu chaihwo hwekupikisa.
Kushandisa kusimba kwakadzika kwebindu kunobatsira kudzivisa zvidzidzo zvako, uye kunogona kuvandudza marongerwo ako nekukwirira uye nemiganhu kana inoshandiswa mumamiriro ezvinhu akakodzera. Kuwedzera kwezvakaitika kunogona kuverengwa pakupa nguva kubva mukati me 3D yako purasi, kana kushandiswa mumashure-kubhizha uchishandisa z-kina kupfuura uye lens blur ku Photoshop. Kushandisa kuitika mumugumo kunowanikwa nenzira yakakurumidza, kunyange zvakadaro kuisa kukama kwebasa mukati memapurogiramu yako epakukupa kunokupa hutungamiri hwepamusoro.

Wedzera Chromatic Abberation
Zita racho rinonzwika zvakaoma, asi kuwedzera chromatic aberration kumashanduro ako ingangodaro nzira iri nyore pane iyi.
Chromatic aberration inowanikwa munyika chaiyo yekuona mapikicha apo lensi inokundikana kupa mifananidzo yose yevaravara panguva imwechete yekutendeuka. Chiitiko ichi chinoratidzika se "maruva fringing," apo kusiyana kwakanyanya kumativi kunoratidza ruvara rutsvuku kana ruvara rwebhuruu.
Nokuti chromatic aberration haiti kuitika muCG chiedza , 3D artists vakagadzira nzira dzekunyengedza ichi chiitiko kuburikidza nokugadzirisa mutsara wepepuru uye webhuruu wekupa pixel kana maviri mu Photoshop
Chromatic aberration inogona kuwedzera kuitika kwekuita, asi inogonawo kupesana kubva kune imwechete apo mhinduro inopfuura. Usatya kuzviedza, asi yeuka kuti unyengeri ndiye shamwari yako yepamusoro.
Sezvandareva, chromatic aberration yakaisvonaka yakazara nyore kushandisa uye Digital Tutors ine maminitsi maviri emaminitsi ekudzidzisa kuti ikuratidzei sei:

Shandisa Specular Maps
Vazhinji vashandi vanodzidza kushandisa mapepa ekunyatsotarisa zvakanaka nguva pfupi, asi zvinonyatsotenderwa kutaurirwa kune ani zvake asati atova pabhodhi.
Mamwe mapoka anotaurira yako injini iyo zvikamu zvemuenzaniso wako zvinofanira kunge zvakanyanyisa (kubwinya) uye izvo zvinofanira kuve zvakanyanya kupararira. Kushandisa mapoka e-specular kuwedzera kwechokwadi nokuti ngatitarise-zvinhu zvakawanda mumasikirwo hazviratidzi maziso akafanana, asi paunobva mepu inonyanya kubuda, ndiyo ndiyo nzira yako yaunopa.
Kunyange kune zvinhu zvinenge zvakasvibiswa zvigadziriswe (yakagadzirwa nekerubamikisi, yakakonzerwa nesimbi) iwe unofanirwa kushandisa mapepa chaiwo kuti ubatsire kubvisa zvinhu zvisina kukwana kubva kumatema, dings, uye dents.

Grunge it Up
Iwe hausi kuona "kukanganisa kweukwana" zvakanyanya sezvawakaita mumazuva ekutanga eCG, asi kune avo vese vanoda chiyeuchidzo: usatya kuwedzera tsvina uye grit kune yako mitero uye mavara.
Zvose zvechokwadi-zvinhu zvenyika hazvina kuchena uye zvakajeka, saka kusiya mifananidzo yako nenzira iyo inogona kuuya seine usimbe uye inenge ichinyadzisa kushuva kwako kwemafoto-realism. Hazvirevi kungova nemashoko ekunyorwa kana-kuedza kuwedzera kukanganisa kukuru uye kuparadza kune vamwe vevatori vako, kunyanya kana uri kushanda mumamiriro ezvinhu emutambo weFPS.
Chengetedza pfungwa yekusina kukwana mupfungwa apo uri kuwedzera zviitiko zvako zvakare. Kunze kwekuti uri kuenda kunzvimbo yakarongeka yakarongeka yemhando yekuratidza, shatisa zvimwe zvigadzirwa zvese mumamiriro ako ose kuitira kuti nzvimbo yacho ioneke inogara.

Wedzera Asymetry
Iko kukwanisa kuenderera mberi nekuenzanisa kana kuenzanisa kana kuveza munhu unhu hukuru-hunoreva kuti sevatungamiri isu chete tinotofanira kuita hafu yebasa uye hatimbofaniri kuzvidya mwoyo pamusoro peziso rimwe rakakura kudarika rimwe, kana kuti tione kuti kuruboshwe cheekbone inosangana nekodzero (munoziva, matambudziko iwayo ane simba anotambudza vanyori vezvetsika nevagadziri).
Asi kana pachisvika nguva yekuita tsanangudzo yekupedzisira uye kuisa muenzaniso wako, iyo pfungwa yakawanda yekuvhara kuenzanisa uye kuwedzera marudzi akasiyana ekusiyana kweunhu hwako.
Zvingave zviri mune pose, zvigadziro, kana zvinyorwa zvinyorwa zvemashoko, asymmetry ichaita kuti maonesheni ako ave akafanana nehupenyu, uye mikana iwe uchazoguma neine simba uye rakabudirira mufananidzo wekupedzisira.
