Inotsvaga vs. Unbiased, Reyes, uye GPU-Kukurumidza
Kana iwe wakapedza chero nguva uchitarisa kune dzakasiyana-siyana zvinoshandiswa injini pamusika, kana kuti uverenge pamusoro pekugadzirisa -mhinduro yekugadzirisa mhinduro , mikana iwe wakawana mashoko akadai sekusarura nekusava nehanya, GPU-kukurumidza, Reyes, uye Monte-Carlo.
Ikozvino kuitika kwechizvarwa chinotevera chizvarwa chakakonzera huwandu hwakawanda hwehuputi, asi dzimwe nguva zvingava zvakaoma kutaura mutsauko pakati pekutengesa buzzword uye wakatendeseka-kuna-god feature.
Ngatitorei mamwe mazwi ekutaura kuitira kuti iwe ugone kuswedera kune zvinhu kubva pane zvakajeka:
Ndechipi Kusiyana Kwepakati Pekutsvaga uye Kusasarura Kunopa?
Kukurukurirana kwechinhu chisingabatsiri kushandura kushandura kana kushandura kwakagadzikana kunogona kuwana unyanzvi zvakakurumidza. Tinoda kudzivisa izvozvo, saka ndichaedza kuichengeta sechinhu chinokosha sezvinobvira.
- Unbiased - Unbiased zvinoshandiswa saMaximwell, Indigo, uye Luxrender zvinowanzotaurwa kuti "zvakarurama mumuviri" zvinopa injini. Kunyange zvazvo "zvakarurama mumuviri" pane chimwe chinhu chinonyadzisa (hapana chinhu muCG chiri chaicho chaicho chepanyama), shoko iri rinoreva kureva kuti mhandara isina kufanirwa inoverenga nzira yechiedza sezvakanyatsotaridzika zvinogona kuitika mukati mechiratidzo chezvino-gen kupa maitiro .
Mune mamwe mazwi, hapana kukanganisa kwakagadziriswa kana "kukanganisa" kunoitwa nemaune. Kusiyana kupi zvese kucharatidza soruzha, asi kunopiwa nguva yakakwana mushanduri asina kusarura achapedzisira achinjira pamathematically "yakarurama" chigumisiro. - Kusvibiswa - Kusvibiswa kwerudziro, kune rumwe rutivi, kuita zvimwe zvibvumirano mukufarira kwehutano. Panzvimbo pokugumburwa kusvikira gumisiro remutsva rave rasvika, zvinyararire zvinoshandiswa zvinoshandiswa zvinyorwa zvichange zvichitsvaga kusarura, uye kushandisa zvinyengeri kunyorwa kana kusvibiswa kuti kuderedze nguva. Dzakashandura zvinoshandiswa zvinogona kuve zvakanyatsogadziriswa kupfuura vasiri vavo vasina hanya, uye mumaoko akanaka, shanduro yakagadzikana inogona kuunza chikonzero chakarurama zvakakwana uye zvishoma nezvishoma CPU nguva.
Saka pakupedzisira, sarudzo iri pakati pejini isina unbiased, inoda zvimwe CPU nguva asi vashoma-vhidhiyo-maawa kuti vashande, kana shanduro yakagadzikana iyo inopa muenzi wacho zvishoma kunyanya kutarisira asi inoda nguva yakawanda yekutsvaga kubva kune unyanzvi hupi.
Kunyange zvazvo pane nguva dzose iri kunze kwehutongi, mapiritsi asingabatsiri anoshanda zvakajeka nokuda kwezvifananidzo, kunyanya muzvivakwa zvekugadzirwa kwezvinhu, kunyange zvakadaro mafirimu, mafirimu, uye mafirimu anokanganisa kushandiswa kweshanduro yakagadzikana inowanzodiwa.
Ko GPU Kukurumidza Kuita Sei?
GPU kukurumidza kuwedzera kukura kwetsva pakupa teknolojia. Mutambo-injini dzakatsigirwa neGPU yakagadzirwa nemifananidzo kwemakore nemakore, zvisinei, zvinongova munguva pfupi yapfuura kuti kubatana kweGPU kwave kushandiswa kushandiswa mune zvisiri chaiyo-nguva kupa maitiro apo CPU yakagara iri mambo.
Zvisinei, nekupararira kwakawanda kwepamburu yeNVIDIA yeCUDA, yakave yakakwanisa kushandisa GPU mumagariro neCPU mumabasa asingabvumirwi kugovera, zvichiita kuti pave nehupenyu hutsva hunofadza hwekushandura maitiro.
GPU-yakagadziriswa renderers inogona kusava nemafungiro, kufanana neIndigo kana Octane, kana kusagadzikana seRedhift.
Ndeipi Renderman (Reyes) Anopinda Mumufananidzo?
Pane imwe nhanho, Renderman anomira pane imwe nguva kunze kwekukurukura kwezvino. Icho chivako chekushandura kwakagadzikana chinotarisana neReyes shanduro, yakagadzirwa makore anodarika makumi maviri akapfuura paPiarar Animation Studios.
Renderman akanyanya kuiswa mumakombiyuta makhizha emabhizimisi, uye pasinei nekukwikwidza mukukwikwidza kubva kune Solid Angle's Arnold, zvingangodaro ichange iri imwe yepamusoro yekugadzirisa mhinduro pamagumo ekupedzisira uye zviitiko zvekudzidza kwemakore akawanda ari kuuya.
Saka kana Renderman ari akakurumbira, sei (kunze kwezvikwata zvakasara munzvimbo dzakadai seCGTalk), haunzwi nezvazvo kakawanda here?
Nokuti yakange isingakonzwiki kuti ishandiswe pakuzvidzivirira-user. Tarisa zvakatarisana neIndaneti CG uye iwe uchaona zviuru zvezvifananidzo kubva kune ra raytracers dzakanaka seVray uye Mental Ray, kana mapeji asina kufanira akaita saMaxwell uye Indigo, asi hazvishamisi kuti awane chimwe chinhu chakavakwa muRenderman.
Ichokwadi chaizvoizvo chinouya pasi pokuti Renderman (saArnold) akanga asina kumbofanirwa kushandiswa zvakanyanya nevaridzi vanozvimiririra. Kunyange zvazvo Vray kana Maxwell vachigona kushandiswa zvakananga nemunhu mumwe chete anozvimiririra, zvinotora timu kuti tishandise Renderman nenzira yaive yakarongwa. Renderman yakagadzirirwa mapaipi emapazi makuru, uye ndiyo iyo inobudirira.
Zvose Izvi Zvinorevei Kumugumo-Anoshandisa?
Chokutanga pane zvose, zvinoreva kune zvimwe zvingasarudzwa kupfuura kare. Kwete kare kare, kushandura kwaiva chinhu chine mashizha matsva munyika yeCG, uye ndivo chete vainyanya kufunga nezvemagetsi vaiita izvi. Pamakore gumi apfuura, kutamba kwave kwakapararira zvikuru uye kufungidzira-kuve kwakagadzirika zvakakwana kune rimwe boka revanhu (muchitarisiko chiripo, zvichida).
Tarisa tarisa hurongwa hwedu huchangobva kubudiswa hunoita kuti injini iwane manzwiro emangwana matsva mhinduro dzakabuda. Kutenga teknolojia yakasvetuka kubva kunze kwebhokisi, uye itsva mhinduro dzakadai seOctoane kana Redshift dzakasiyana zvakasiyana nemasikirwo ekare saRenderman zvokuti anenge asingatombogoni kuenzanisa.
