The 2m2k3r
Nechizvarwa chega chega chevanyaradzi - parizvino inoperekedzwa neanotakurika consoles, makomputa uye smartphones -, matekinoroji ekucheka anobuda uye anovandudzwa kuti aite zviitiko zvakagadzirwa muindasitiri yemitambo yemavhidhiyo zvinotonyanya kuitika uye kunyudza. Iyi ndiyo nyaya ye Ray achitevera. 55c3c
Avo vanonakidzwa nemitambo vari kuramba vachiwedzera kudiwa maererano nekuita uye magirafu, uye makambani ari kuisa magiya avo mugiya rakazara kuunza mhedzisiro pane inowedzera simba hardware. Mumwe wemapiyona mumakadhi akazvitsaurira evhidhiyo ekutamba ari NVIDIA, uye ijana rakewo rokuva piyona murudzi urwu rwezvishandiso. Ngationei zvishoma nezve tekinoroji yekuda iyi.
Chii chinonzi Ray Tracing? 6q4d3r
O Ray achitevera ndeye vhidhiyo kadhi akateedzera tekinoroji GeForceRTX, iyo inovimbisa kushandura misika uye kurega, nekufamba kwemakore, makadhi akatevedzana 1000. Iyi ndiyo graphic processing resource ine chokuita nekuvhenekera munzvimbo uye zvinhu zvemitambo zvakasiyana kubva kune zvatakajaira, kuvandudza maitiro emifananidzo akadai semumvuri, kuratidzira, ambient occlusion, pakati pevamwe. Izvi zvinoitika nekuburitsa mwaranzi pazvinhu pachinzvimbo chekushandisa mwero wemwenje wezvinhu. mitambo injini current.
Iyo tekinoroji inosanganisira, yekutanga, yealgorithm inokwanisa kugadzira iyo inonzi BVH (kubatanidza vhoriyamu hierarchy), rudzi rwe data data inokwanisa kuita chaiyo-nguva ray tracing. Mushure mekuverenga kupindirana pakati pedanda uye chiitiko chiri mubvunzo, zvinosarudzwa kuti ndeipi kugadzirisa kunofanirwa kuitwa - iyo ray inogona kuratidzwa, kugumiswa kana kupindirana nezvimwe zvinhu zvechiitiko panguva yayo.
Muchinguva chechipiri, mushure mekugadzira mepu kupindirana kwese kwakaitika (nzira yekutsvaga), rudzi rwechifananidzo chegranular chinoumbwa, chinoratidza maitiro akadai sekudzika uye ruvara. Uku kugadzirisa kuburikidza neyepamberi Artificial Intelligence, inozivikanwa sekuderedza ruzha (denoising), inoshandura zvakavimbika seti yemapoinzi kuita furemu (mufananidzo) wechiitiko.
Isu tinofanirwa kuyeuka kuti zvese izvi zvinoitika munguva chaiyo, saka iyo yese gadzirira Iyo PC yemitambo iri mubvunzo inofanirwa kunge iri kuenderana nezvinodiwa zvishoma.
Zvakanakira nezvayakaipira 156d5e
Mhedzisiro ye-post-processing effects, zvichipiwa kuwanikwa kweplateti GeForceRTX e Hardware inowirirana, inoshamisa zvikuru. Panyaya ye kuvharwa kwekamuri (ambient occlusion), mumvuri uripo munzvimbo dzine musiyano mukuru wemwenje, tinogona kuona kuti mhedzisiro inoitika zvakanyanya mukuona kusinganzwisisike kwekusviba, nekunzwa kwechokwadi kwekudzika.
About the mimvuri (shadows), iyo ray projection technique inokubvumira kuti uone kana chinhu chiri kudzivirira danda iri kusvika kwarinoperera. Kuburikidza nekunangidzira kunoitika pamusoro pechinhu uye kuenzanisa kwemasvomhu, zvinogoneka kuona kuti chinhu chacho chii uye kuti chinozvibata sei maererano nezvinovheneka zvine hudzamu uye nemazvo.
Os reflexes ru Ray kutsvaga zviri pakati pezvakanakira zvemazuva ano magirafu emakombuta. Kusvikira munguva pfupi yapfuura, kuwana mazinga emhando yaikwanisika chete kuburikidza mimvuri programmable - iyo yaisagara ichizadzisa basa ravo zvinogutsa nekuda kwekudiwa kukuru kwekugadzirisa. Mhedzisiro yacho inogona kucherechedzwa pane inopenya kana yakawanda opaque nzvimbo, paine mamwe kana mashoma maramu emwenje ari kutungamirwa uye kurongerwa kumushandisi nenzira ye pixels.
Pakati pezvakaipira mitengo, iyo inotangira paUS$500 kusvika paUS$2500 zvichienderana nemhando dzacho. Vamwe vagadziri vanopa sarudzo ne mvura inotonhora (kutonhora kwemvura), izvo zvinowedzera kuwedzera kukosha. Kune zvakare dzimwe nzira dzakachipa zvinoenderana nemugadziri, asi mitengo inotenderera yakatenderedza kukosha kwakatemwa neiyo NVIDIA.
Munguva pfupi yapfuura, iyo NVIDIA yakatanga mutsara mutsva wemakadhi evhidhiyo anounza tekinoroji Ray kutsvaga semusiyanisi mukuru. Ku GeForce RTX SUPER 2060, 2070 uye 2080, ishanduko dzakananga dzeshanduro dzakajairwa dzezita rimwe chete, uye dzinouya ne8 GB yeGDDR6 RAM, inosvika 15.5 Gbps yekumhanya kwendangariro, uye wachi inosimudzira pamusoro pe1.800 MHz.
Nezvemitengo, iyo RTX 2060 SUPER, modhi ine mamwe magadzirirwo ekutanga, yakasvika musi wa9 Chikunguru nemitengo inotangira paUS$399. RTX 2070 e 2080 SUPER, ichaita US$499 uye US$699, zvichiteerana. A NVIDIA inopa pasuru kune avo vanotora makadhi matsva evhidhiyo mumutsetse RTX SUPER, kusanganisira mitambo Wolfeinstein: Youngblood e masimba. Kuti uwane rumwe ruzivo nezve maGPU matsva kubva NVIDIA, tarisa chinyorwa chedu chakakosha nezve kuburitswa:
Mitambo ine Ray yekutevera rutsigiro 1f282
Nechiziviso chechangobva kuitika chezvakajairwa zveiyo inotevera console mumhuri Dreamcast uye yakatevera turera inoratidza Project Xbox Scorpio, tinoziva kuti michina ine simba ichauya ichatsigira Ray achitevera. Kunyangwe muna 2019, mimwe mitambo kubva kumakambani makuru yatove nerudzi urwu rwerutsigiro kuita kuti ruzivo ruve rwechokwadi.
Pakati pe mitambo yakaburitswa inoenderana neray tracing, tine Mumvuri PAGUVA Raider, Metro Exodus, Battlefield V, Assetto Corsa, Quake II RTX uye yekutanga kupinda vhezheni ye Gara muChiedza. Nezvemitambo isati yaburitswa, inonyanya kukosha ndeye Wolfeinstein: Youngblood.
Tinogona chete kumirira zvimwe zviziviso zvemazita anotsigira tekinoroji inokurukurwa muchinyorwa - saka ramba wakatarira Showmetech kuti uwane zvese nezvemitambo uye tekinoroji.
