Kusayanjanitsika vs. Kusayanjanitsika, Reyes, ndi GPU-Acceleration
Ngati mwagwiritsa ntchito nthawi iliyonse kuyang'ana injini zosiyanasiyana pamsika, kapena muwerenge za njira zowonetsera okha , mwayi kuti mwakumanapo ndi mawu monga kukondera ndi osasamala, GPU-acceleration, Reyes, ndi Monte Carlo.
Zotsatira zamakono zotsatila mbadwo wotsatira zakhala zikuchuluka kwambiri, koma nthawi zina zimakhala zovuta kufotokoza kusiyana pakati pa buzzword ya malonda ndi chinthu chowonadi kwa mulungu.
Tiyeni tiwone zina mwa mawu kuti muthe kuyandikira zinthu mwawona bwino:
Kodi Kusiyanasiyana N'kutani Pakati pa Kusokonezeka ndi Kupanda Phindu?
Kukambitsirana kwa kutanthauzira kosasinthika motsutsana ndi kumasulira kosasinthika kungapangitse luso mwamsanga. Tikufuna kupeĊµa izo, kotero ndikuyesera kuziyika monga momwe zingathere.
- Osayanjanitsika - Operewera osayamika monga Maxwell, Indigo, ndi Ludzu amavomerezedwa ngati "olondola thupi" amapanga injini. Ngakhale kuti "chidziwitso cha thupi" ndi chinthu cholakwika (palibe chomwe chiri mu CG chiri chowonadi mwathupi), mawuwa amatanthawuza kutanthauzira kuti mzere wosasinthika umawerengetsa njira ya kuwala monga momwe tingathere polemba momwe tingagwiritsire ntchito njira zatsopano zopezera maonekedwe .
Mwa kuyankhula kwina, palibe vuto lovomerezeka kapena "nkhanza" lomwe limayambitsidwa mwadala. Kusiyanasiyana kulikonse kudzawonetsa ngati phokoso, koma kupatsidwa nthawi yokwanira yopereka mosasinthika pamapeto pake idzasinthika pa zotsatira za masamu "zolondola". - Kutsekedwa - Kutsekedwa ndi mafilimu, pambali ina, amavomerezana ndi chidwi. M'malo mogwedezeka mpaka phokoso lamveka lafika, akatswiri okonzeka amatsutsa zotsutsa, ndipo amagwiritsa ntchito mawu osokoneza bongo kapena amawombera kuti achepetse nthawi. Zithunzi zosakanizidwa zimatha kukhala bwino kwambiri kusiyana ndi anzawo osaganizira, ndipo m'manja mwanu, mpiritsi wosakanikirana angathe kubweretsa zotsatira zolondola ndi nthawi yochepa ya CPU.
Choncho pamapeto pake, chisankhocho chili pakati pa injini yopanda ntchito, yomwe imafuna nthawi zambiri za CPU koma ochepa maola ojambula ntchito, kapena mpangidwe wotsatsa zomwe zimapatsa ojambulawo mphamvu zambiri koma kumafuna ndalama zochuluka kuchokera kwa wothandizira.
Ngakhale kuti nthawi zonse pamakhala malamulo osiyana, mafilimu osagwirizana nawo amagwira bwino ntchito zowonetsera mafano, makamaka muzithunzi zojambula zomangamanga, komabe mafilimu, mafilimu, ndi ziwonetsero zimatsutsana kwambiri ndi zomwe zimapindulitsa.
Kodi GPU Imapangidwira Bwanji?
Kuthamanga kwa GPU ndi chitukuko chatsopano popereka teknoloji. Mitundu ya masewera yakhala ikudalira zithunzi za GPU zaka ndi zaka, komabe, posakhalitsa kuti kugwirizanitsa GPU kwafufuzidwa kuti igwiritsidwe ntchito m'malo osapereka nthawi yeniyeni pomwe CPU yakhala mfumu.
Komabe, pofalikira ponseponse pa nsanja ya CVA ya NVIDIA, zinakhala zotheka kugwiritsira ntchito GPU polemba ndi CPU mu ntchito zopereka zopanda pake, zomwe zimapangitsa kuti pakhale ntchito yatsopano yosangalatsa yoperekera ntchito.
GPU-acclerated renderers sangakhale osayanjanitsika, monga Indigo kapena Octane, kapena kukondera ngati Redshift.
Kodi Renderman (Reyes) Ali Kuti Ali M'chithunzi?
Pa mlingo wina, Renderman amaima mosiyana ndi zokambirana. Ndizojambula zosasinthika zochokera kumasinthidwe a Reyes, opangidwa zaka zoposa 20 zapitazo ku Pixar Animation Studios.
Renderman alimbidwa kwambiri mu makina opanga makompyuta, ndipo ngakhale kuti akukwera mpikisano wochokera kwa Alnold Angle, ingakhale imodzi mwa njira zowonjezeretsera zowonjezereka pamapikisano othamanga ndi zotsatira za maphunziro kwa zaka zambiri zikubwerazi.
Kotero ngati Renderman ndi wotchuka kwambiri, bwanji (pambali pa mapepala apadera kumalo ngati CGTalk), kodi simukumva za izo nthawi zambiri?
Chifukwa chakuti sizinapangidwe kuti apange omasuka okha. Yang'anani kuzungulira gulu la CG pa Intaneti ndipo muwona zithunzi zambirimbiri kuchokera ku raytracers monga Vray ndi Mental Ray, kapena mapepala osakondera monga Maxwell ndi Indigo, koma ndizosavuta kuti apeze chinachake chomwe chimamangidwa ku Renderman.
Zangowonjezera kuti Renderman (ngati Arnold) sanayambe kugwiritsidwa ntchito kwambiri ndi ojambula okhaokha. Ngakhale Vray kapena Maxwell angagwiritsidwe ntchito movomerezeka ndi wojambula mmodzi yekha, zimatengera timagulu kuti tigwiritse ntchito Renderman monga momwe anafunira. Renderman anapangidwa kuti apange mapaipi aakulu omwe amapanga, ndipo ndipamene zimakula.
Kodi Zonsezi Zimatanthauza Chiyani kwa Otsiriza?
Choyamba, zikutanthauza kuti pali njira zambiri kuposa kale lonse. Osati kale kwambiri, kutembenuza kunali kachipangizo kakang'ono mu dziko la CG, ndipo okhawo akatswiri odziwa zamakono anali ndi mafungulo. Kwa zaka khumi zapitazo, masewerawa adayambitsa zambiri komanso zithunzi zowona zithunzi zakhala zikupezeka bwino kwa gulu limodzi la anthu (muchithunzi chokha, makamaka).
Onani mndandanda wa makina otere omwe watulutsidwa posachedwapa kuti amve kuti pali njira zingati zatsopano zowonekera. Kupereka zipangizo zamakono zatuluka mu bokosi, ndipo njira zatsopano monga Octane kapena Redshift ndi zosiyana kwambiri ndi kafukufuku wakale monga Renderman moti sizingakhale zomveka kuziyerekeza.
