Siiya - waxa uu yahay waxan? Sida loo reserved?

xubno badan oo ka mid ah deegaanka muuqaal aadanaha oo casri ah ayaa maanta waxaa lagu abuuray isticmaalaya barnaamijyada naqshadeynta computer. Aan muuqaalaynta dhigay 3D-fanaaniinta, ma aan samayn karo wax studio naqshadda ama design ama saarayaasha kulan computer. technology ee abuuraya images sida - photorealistic ama simulating farsamooyinka kala duwan tahay - wuxuu ka kooban yahay dhowr tallaabo nidaamka. Siiya - Waa waxa ugu muhiimsan ee iyaga ka mid ah, qayb ka mid ah final, taas oo go'aan ka natiijada kama dambaysta ah.

Asalka ereyga

Erayga "abaalmarin" (ama "haya'ad") waa, sida aad u badan oo la xidhiidha teknoolajiyada ku salaysan IP, ka luqadda Ingiriisiga. Waxay ka timaadaa rendre ee Old Faransiis, taasoo la micno ah "in la sameeyo", "si ay u", "dib", "dib". Xididdada qoto dheer ee falka dib ugu Latin qadiimiga tagaa: re - Horgalaha taasoo la micno ah "dib", iyo ku dhicin - "siin".

Sidaa - mid ka mid ah macnayaasha casriga ah ee erayga. Siiya - tani ay ka mid yihiin hannaanka dib u dhiska image planar ku salaysan model saddex geesood ah oo ka kooban macluumaad ku saabsan guryaha jirka ah ee shayga - ay qaab, texture dusha, nalalka iyo wixii la mid ah.

Siiya iyo muuqaalaynta

hoos ugu degtay galay ereyada kuwa xirfad ku hawlan teknoolajiyada digital abuuro images, eraygan waxa loo sii kordheysa loo isticmaalay in isticmaalka maalin walba. Bixi diyaar abaalmarin weydiinaya, tusaale ahaan, marka amro alaabta - hal shay ama xaalad qol, iyo in design ah ee gudaha ama haya'ad oo dhan ee dhismaha - taasi waa mid ka mid ah hababkii ugu weyn ee uu u gudbiyo macmiilka macnaha dhise ama fikrado naqshadeeye ee.

Waxaa jira isku, la mid ah in macnaha iyo inta badan loo isticmaalaa in jawi caadi ah, in kasta oo dheeraad ah oo eheeyn - muuqaalaynta. Ka mid ah muuqaallo kale xirfadle naqshadda ama ciyaaraha computer maanta go'aansaday in ay takhasuska cidhiidhi ah, waxaa jira kuwa ku hawlan yihiin Qaabaynta - abuurista waxyaabaha saddex dhinac-cabbir ah, iyo kuwa ay bixiyaan haya'ad ee goobta la dhammeeyayna ay - dhigeysa nalalka, dooran fikrad iyo nooc, ka dibna uu bilaabo barnaamij haya'ad ah.

qeexo

Ereygan waxa uu leeyahay dhowr macne:

• Siiya ama haya'ad, - habka helo farsamo ama farshaxanka planar haya'ad image bitmap Qase, 3D Max, shineemo, - ku salaysan lagu daydo digital saddex dhinac-cabbir abuuray isticmaalaya baakadaha software gaar ah Maya et al.
• Siiya - waa, in fact, natiijada habka noocan oo kale ah - raster a image, sawir, iyo sidoo kale characters image iyo deegaanno kulan video ama by videos trideshnikami loo isticmaalo wax soo saarka ee filimada - caadi ah ama kartuun.
• Siiya ama renderer - sidaas loo yaqaan software gaar ah, taasi oo ka taas oo ay jirto isbadal ah 3D-daydo in image ah. Codsiyada noocan oo kale ah waa la dhisi karaa xirmo naqshadeynta ama codsatay sida codsiyada kala duwan: RenderMan, Ray Maskaxda, V-ray, Corona, Brasil, Maxwell, FinalRender, Fryrender, joogana iyo kuwo kale oo badan. Eebay, iyo sidoo kale wax kasta oo xidhiidh la leh technology digital, joogta ah updated. Waxay yihiin algorithms kala duwan loo isticmaalo ee dhimista xogta oo ka mid ah astaamaha lagu daydo iyo xeeran. On ay ku salaysan nidaamka haya'ad oo dhan, oggolaadaan in aad si ay u abuuraan aad alaabta, nalalka, kamaradaha, iyo wixii la mid ah. N.

Noocyada haya'ad: online iyo prerendering

Waxaa jira laba nooc oo asaasi ah haya'ad, ku xirantahay xawaaraha at kaas oo ka dhici waa in la helo image dhamaystirtay. First --waqtiga dhabta ah haya'ad loo baahan yahay in shaxda la wada qabanayo, inta badan ciyaaraha kombuyuutarka. Halkan waxaan u baahan degdeg ah u abaalmarin, image waa in la isla soo bandhigay, si inta badan goobta loo xisaabiyo in horay iyo waxaa lagu kaydiyaa foomka xogta shakhsiga. Kuwani waa qaabab in la qeexo muuqaalka kore ee waxyaalaha iyo iftiiminta. Barnaamijyada loo isticmaalo haya'ad online, iyadoo la isticmaalayo inta badan khayraadka kaarka naqshadeynta iyo xusuusta computer ee, iyo ilaa xad yar - processor ah.

Moodo Muuqaallo adag more aragga, iyo sidoo kale halkaas oo arrinta xawaaraha ma aha sidaas la xiriira sida ay ka muhiimsan tahay tayada haya'ad ah, iyo habab kale oo loo isticmaalaa in lagu abaalmarin barnaamijka. Xaaladdan oo kale, awood buuxda ee Processor multi-muhiimka ah, soo bandhigay fursado xal, qaabab, hoos ugu sareeya xogta iftiiminta. Inta badan loo isticmaalo, iyo haya'ad postprocessing, kaas oo u ogolaanaya Heer sare ah ee photorealism ama la doonayo saamayn farshaxanka.

Hababka for haya'ad goobta

Doorashada hababka diyaarinta image waxay ku xiran tahay dhibaatada gaar ah oo inta badan by doorashada shakhsi iyo waayo-aragnimo ee visualizer ah. In la sameeyo hab cusub oo hal abuur haya'ad - ama takhasus sare leh ama universal. Maanta, wadnaha ee renderer ah software ugu badan ku salaysan yahay saddex hab xisaabeed oo aasaasi ah:

• Rasterization (Scanline) - hab kaas oo sanam loo abuuray yaraysi ma shaqsi dhibco, pixels, iyo oo dhan wejigooda, geesoolayaashu iyo oogada ee qaybo badan. Qaabab qeexaya guryaha shay sida nuurka oo kale ee goobta, sida ay ugu jirto xogta beddelin. image keentay inta badan ma ka tarjumaya aragtida ee isbedel Nuur, si qoto dheer oo duurka , iyo wixii la mid ah. D. Inta badan ee loo isticmaalo in lagu abaalmarin goobaha kulamada iyo nidaamyada in videoprodakshene.
• Ray Raadinta (Raytracing) - goobta physics xisaabiyaa ku saleysan rays kaas oo ka siku camera dalwaddii of dogob kasta iyo falanqaynta soo wajahda alaabta oo ay dhacdo in goobta. Iyadoo ku xiran tirada iyo tayada "bounces" simulates milicsiga ama refraction iftiinka, midabka, u damaysay iyo D. Tayada image ka dhalanaya marka la barbar dhigo rasterization si on. Waa sareeyaa, laakiin ay xaqiiqo u leeyihiin in ay bixiyaan isticmaalka sii kordhaya ee khayraadka.
• Xisaabinta iftiinka ka muuqataa (Radiosity) - qodob kasta oo pixel kasta image waxaa ka fadilnaa midabka ah in madax bannaan yahay camera ah. Waxaa saamayn ku ilaha caalamiga ah iyo kuwa maxalliga ah ee iftiinka iyo deegaanka. hab noocan oo kale ah oo u ogolaanaya xisaabinta of muuqaalka on hannaankii dusha iyo midab of shakhi iftiin ka alaabta ku xiga.

Practice muujinaysaa in nidaamka haya'ad ugu horumarsan iyo caansan isticmaalaa isku-dar ah oo dhan ama hababka ugu waaweyn. Tani waxay u ogolaaneysaa ugu badnaan photo-xaqiiqo oo xaqiiq tahay in khariidaynta ee geeddi socodka jirka ee goobta la siiyo.

haya'ad isku xigxiga

Inkasta oo hab casri ah muuqaallo kale computer, waxay door bidaan in loo qoondeeyo in ay abaalmarin wajiga gaar ah, kaas oo ku lug leh aqoon gaar ah iyo xirfadaha, dhab ahaantii, waa lagama sooci karo nidaamka oo dhan diyaarinta muuqaalaynta ah. Haddii, tusaale ahaan, la saadaaliyey haya'ad gudaha ku xirnaan doontaa nooca qalabka loo isticmaalo, iyo nidaamka imaging kasta geynta ee simulating texture texture iyo dusha sare.

Isla sidaas u dhaqmaan habab of nalalka goobta. Dejinta iftiin dabiici ah oo macmal ah, iyo sifooyinka hooskiisay dhibic u gaar ah, hummaag, xoog, saamaynta is-Nuur - tallaabada xigta ee la abuurayo muuqaalaynta goobta a. Sida loo dhigay ilaa a abaalmarin waxay ku xiran tahay software-ka loo isticmaalo iyo waxqabadka nidaamka. Khariidad walba iyo barnaamijka-visualizer ayaa subtleties iyo Gudigga ay.

Tusaale ahaan, Corona Renderer ayaa goobaha hagaajin karo si toos ah inta lagu guda jiro jiritaanka image finalka. laambadihii xoogga la bedeli karaa online, qabsato midabka, macaamiloon.

-Processing Post natiijada ka abaalmarin

Waayo, shaqo gaar ah, waa macquul in la codsado farsamooyinka imaging gaar ah. naqshadaha wuxuu u baahan yahay siyaabo kale ah ee ra'yi dhiibashada badan leh sawir farsamo. Siiya xagga dibedda, tusaale ahaan, inta badan wuxuu u baahan yahay hanti artist ee baakadaha muuqaallo la images bitmap, kuwa ugu caansan kuwaas oo ka shaqeeya - Adobe Photoshop. Oo had iyo jeer ma sameeyaan si kor loogu qaado photorealism ah. -rogga ah ee hadda ku xaraynta ka mid ah dayashada naqshadda ee gacanta ku-sawir - watercolor, gouache, sawir khad, iwm ...

postprocessing haya'ad tayo sare leh sida caadiga ku bilaabanto xulashada format la doonayo file, soo saaray ka dib markii dhamaadka barnaamijka. Waxa laga hirgeliyey image finalka hayn layers, baaskiil channels midabka shaqsi. Tani waxay suuro gelineysaa in la gaaro natiijada sare ee hoos oo dhan layers sawirka guud, iyadoo la isticmaalayo goobta badan oo sax ah iyo khiyaano midabka.

Siiya iyo waxqabadka nidaamka

Bandhigyada muuqaalaynta tayo ku xiran tahay ma aha oo kaliya on nidaamka software ah. On line hoose waxay saamaysaa awoodda isticmaalo oo ay ku "bir ah". Gaar ahaan factor this saameyn ku xawaaraha - goobta mararka qaar adag waa buriyay dhawr maalmood, haddii computer uusan haysan RAM ku filan ama processor uu leeyahay wax soo saarka hooseeyo.

Sidee si loo dedejiyo haya'ad iyo in la wanaajiyo natiijada kama dambaysta ah, haddii khayraadka yar yihiin? Waad beddeli kartaa goobaha barnaamijka, diido in qadar macquul ah xal wax qaabab iyo dhameysteen image ah by beddelo ku soo koobin kulan si iftiinka iyo hooska khiyaameeyay meelaha waawayn, iyada oo aan si faahfaahsan u xad-dhaaf ah iyo wixii la mid ah D.. Haddii aad leedahay shabakad, waxaad isticmaali kartaa renderer Dufcaddii, marka hoos xogta awood image lug kombiyuutarada kale.

siiya beeraha

Maanta waxaa suurtagal ah in ay isticmaalaan awood fog kooxahaasi computer in ay bixiyaan adeegyada processing Dufcaddii 3D-files. nidaamka waxqabadka sare waxan kartaa in muddo gaaban loo arki ah goobaha ugu adag oo aad u daran. Waxay ula qabsadaan wax saameyn muuqaal xitaa ayadoo ay abuureyso files video ah muddo dheer.

La xiriir bixiyaha adeegyada sida, liiska oo had iyo jeer waxaa laga heli karaa internetka, qiimaha la isku raacay iyo file shuruudaha diyaarinta, waxaad badbaadin kartaa xaddi leh on xawaaraha iyo gaaro heerka loo baahan yahay ee tayada image finalka. At asturidda shirkadaha kuwaas waxaa kor waa in dhowr kun oo Processor iyo boqolaal terabytes ee RAM. Siiya beer xisaabi kharashka shaqada, ku salaysan mugga of file isha iyo wakhtigii loogu talagalay muuqaalaynta waxqabadka. Tusaale ahaan, qiimaha hal 1920x1080 jir, waayo, haya'ad on qalabka caadiga ah taas oo u baahan 3 saacadood ku saabsan yahay 100 rubles. Goobta waxaa loo xisaabaa 8 daqiiqo.

doorasho sax ah

Jawaabta su'aasha ah ee sida loo sameeyo haya'ad of qaab yar oo fudud oo ah shayga ama saamaynta muuqaalka bandhigidda animation qani ku ah tuulada waab, ayaa soo jeedinaya in hab ka duwan. In the case of layliga madax banaan oo shaqo ah sida loo baahan yahay in si fiican loo xulo software ah iyo in la xaqiijiyo awood ku filan oo qalab computer. Si kastaba ha ahaatee, wajiga ugu dambeeya ee shaqada - haya'ad - waxay ku xirnaan doontaa in aad ku qanacsan tahay natiijada kama dambaysta ah.
