FXAA - ndichiyani? The njira kusalaza. kuwongola masewera

Izo zakhala nthawi imene masewera chinali chosangalatsa kosewera masewero ake okha: The player kale anakhala wovuta, makamaka, napempha kuti khalidwe tikuonera chophimba fano. Pa nthawi yomweyo, anthu ochepa mukudziwa kuti pofuna mkulu mlingo wa khalidwe lero, ambiri masewera kutukula ntchito FXAA antialiasing. Kodi ndi - amadziwika lero si onse opanga masewera, ndi zina zambiri amaganiza, ngati m'pofunika monga mbali.

Ambiri osakhala a osewera amadziwa zomwe zimapanga otchedwa makwerero pa m'mbali mwa zinthu, komanso momwe mukhoza vutoli mwa ntchito «odana aliansing» kapena kungoti "odana aliasing".

Kodi dithering?

Kuwongola - ichi ndi chinthu chabwino, monga kuzindikira kwambiri za chifanizirocho ndi mavuto masiku ano masewera, imene si ntchito, pamapeto pake zambiri kuti booed. Pa nthawi yomweyo amakhalabe osagwira njira imene anazindikira FXAA antialiasing. Chimene icho chiri, owerenga ambiri ngakhale chidwi, koma mfundo ndi kukhazikitsa amakhudza khalidwe la fano komaliza.

Osauka kukhazikitsa zambiri chifukwa kuti zida chandamale ali osakwanira kompyuta mphamvu. Inde, zinthu yabwino apa ndi anthu amene amakonda kusewera pa PC, monga mu nkhani iyi, mphamvu zida ndi mwachindunji amadalira mwayi chuma mwini, koma kutonthoza opanga masewera zambiri kokwanira kosewera masewero, monga khalidwe la zithunzi mu ambiri a anthu pa milandu makompyuta zambiri bwino poyerekeza ndi zomwe zithunzi ndi kutonthoza masewera. Komabe, aliyense ali ndi ufulu wosankha komwe ndi zimene sewero lake.

FXAA ndi chiyani?

Mwakucimbidza tisaiwale kuti ndithu nthawi yaitali igrodelov ntchito FXAA odana aliasing luso. Kodi izo, sanadziwe ndiye, koma ntchito yoyamba opezeka mu MMO M'badwo wa Conan, komanso wotchuka onse pa dziko chowombelera MANTHA masewera Komabe, ntchito yekha choyambirira Baibulo la odana aliasing, umene panthawi imeneyo unali osati kwambiri ntchito njira.

Mu nthawi yathu masewera ife ntchito mtundu FXAA yosiyaniranapo. Ndi chiyani icho? Amayimira onse Fast pafupifupi Anti-Aliasing, yomwe ndi njira zothandiza kwambiri poyerekeza ndi luso miyambo MSAA. Izi umodzi chikudutsa mapikiselo shader, limene limakhalapo chimango miscalculation anachita pa siteji ya pambuyo processing. shader chinalengedwa monga yachidule, amene ali oumirira pa yosungirako poyerekeza ndi pamwamba, koma ubwino luso amalipira ntchito, komanso khalidwe. Ataona zimenezi, ambiri amaganiza kuti luso sikuthandiza. Ndipotu zimenezi si zoona.

Kodi ubwino wa njira imeneyi?

Kuwongola losiyana FXAA m'njira zambiri kuphatikizapo bwino kuwongola otchedwa subpixels, ndi specular. An boma chikalata Timoteo Lotts mapulogalamu a sayansi imanena kuti katunduyo ndi zoikamo sing'anga khalidwe amachita pambuyo processing mafelemu pamaziko a chikalata cha 1920x1200 ndi GTX 480 pa mtengo wa millisecond n'komwe.

Ubwino waukulu ali wotsutsa-aliasing FXAA, MUKACHULUKIDWE zimene apa ntchito kuwongola aligorivimu boma pixels, lomwe ndi zosavuta poyerekeza ndi MLAA aligorivimu, amene ali okwanira kwambiri kuti ntchito zida kuti amayendera mlingo DirectX9. Kuti, mu nkhani iyi, pambuyo processing ikuchitika chikudutsa limodzi, ndi chidwi kwambiri ndi ufulu kotheratu kwa zomwe zinali GPU kugwira ntchito zowerengetsa API. Komabe, palinso wina drawback - pa kutukula njira imeneyi ayenera kukhala ophatikizidwa zosiyanasiyana masewera. Pa nthawi yomweyo, miyambo odana aliasing luso ntchito kapena M'malo mwake, simungathe ntchito pa mlingo woyendetsa. Choncho, pamene mapulogalamu ntchito mu injini awo njira kuwongola kwakukulu kwambiri, chotero sati ntchito zawo injini FXAA code, zidzakhala zosatheka kukwaniritsa zotsatira ankafunila, monga kusintha kuchokera kunja code sikunali kotheka mpaka posachedwapa.

Kodi vuto lingathetsedwe bwanji?

Pa ntchito batani [Imani] Pa nthawi, anaganiza poyamba atchule FXAA d3d.dl kachidindo mu laibulale, chifukwa mu mwayi wa kusintha kusintha zotsatira kudzera owona osiyanasiyana kasinthidwe, komanso athe kapena zongolimbana FXAA. akonzedwa Izi owona poyamba liwonerere kwa Directory kumene file executable alipo DX9 ofunsira, komanso kugwiritsa ntchito oyambitsa adzatola laibulale imene malamulo olondola alipo. Pa nthawi yomweyo, monga mapulogalamu kukhazikitsa luso malamulo mu laibulale unali anaonetsetsa kuti zotsatira za ntchito anaiika chipika, mapulogalamuwanso mwachangu anayamba kuzindikira nsikidzi mu njira imeneyi, amene mwamsanga tikonze. C ndi "jakisoni" anaonekera pa nthawi ndi malamulo kwa DirectX 10 akamagwiritsa 11.

Kodi kuonanso?

Zotsatira odziwika ndi kudziwa zimene agwiritsa ntchito njira kwakukulu kwambiri kuwongola ndi FXAA, akhoza kukhala masewera World ya akasinja.

Ngati FXAA odana aliasing si ntchito, amayamba kudziwonetsa osiyana "escalator", ndipo ngakhale kuti thanki chitsanzo kungakhale ndithu lalikulu ndi zimasiyana mwatsatanetsatane wamakhalidwe, zakale amaoneka kwambiri, makamaka pankhani zosiyanasiyana zinthu woonda. anamanga-mu njira odana aliasing akuyesera mu njira mafuta m'mphepete mwa chinthu, koma fanolo mediocre, osanenapo chakuti chithunzi Nthawi zina anangotengeka.

Kodi kusintha kumachitika?

Kamodzi anazimitsa FXAA chida, chifukwa chomveka: zinthu zakale kutha kwathunthu, koma pali ena blurring za chifanocho. Komanso pali wapadera Baibulo FXAA chisoni. luso mapulogalamu mu Baibulo limodzi anawonjezera fyuluta kumunda, amene anatengedwa kuchokera MPC-HC, pamene zotsatira zake zomalizira anali wakhalidwe labwino ndithu: chikusokosera kwathunthu kutha, mawonekedwe ndi kochititsa chidwi kuposa view kuposa choyambirira, ndi "makwerero", ngakhale ntchito ya sefa ndi pafupifupi kwathunthu kwina. Tsopano inu mukudziwa zomwe mtundu FXAA mu World ya akasinja masewera. Chifukwa chakuti olemba sanali poyamba anakonza kotero sharpness ya kapangidwe ka akhoza pang'ono "gwetsa" la nsanjayo, koma kosewera masewero ndi pafupifupi wosaoneka.

Magwiridwe pano pafupifupi osati yafupika. Kumene, World ya akasinja injini ntchito n'zosadabwitsa Ndipo tsono Kasupe kapena M'malo mwake, ntchito kuchepa m'kupita kwa nthaŵi kutuluka kuchokera popanda kanthu.

NoAA, SMAA kapena FXAA

Ngati Tikayerekeza modes «noAA» kapena SMAA ndi «FXAA mukhale» chithunzi zidzasintha kwambiri kwa bwino mu Zikatero. Nokha pano ndi ntchito m'munda fyuluta kuti itsekeke pang'ono kwambiri mizere woonda kwambiri, makamaka, makamaka noticeable wokwera zida zankhondo pamaso. chiwerengero cha mafelemu pa mphindi chimake FXAA kwambiri kuposa chimake m'mbuyomu.

Mu njira ya mayesero yaitali, padatsimikiza kuti ntchito FXAA ntchito akutsikira pafupifupi 10-12% ali choncho pamene ntchito njira kuwongola MSAA 4x, amene khalidwe competes lero ndi luso FXAA, ndipo amachita kuwonetsera ntchito dontho 50% kapena zambiri.

Pezani

Mu 2011, kunalinso Baibulo customizable jakisoni wa matenda, zimene zinaphatikizapo zonse mungachite pamwamba FXAA ndi ubwino wawo. Mu msonkhano umenewu panafika anthu ambiri ndithu Zosefera, mwa womwenso kuti:

• Blur.
• Vignetting.
• mtundu machulukitsidwe.
• Sepia.
• Ndi ena ambiri.

Zonsezi N'zosavuta kwa sintha kudzera file limodzi, ndi zothandiza kwambiri iyi: zoikamo zikhoza kusinthidwa, ngakhale posewera, chabe kuchepetsa ntchito, kutsegula Zikhazikiko Editor, kukuza pulogalamuyi ndi kusangalala zoikamo latsopano popanda Chisudzulo Chikuwononga ntchito kuti muli ndi chidwi. Choncho, latembenuka kuthetsa kuchepa mphamvu pambuyo kutsegula Kukulitsa fyuluta, kupereka bwino chithunzi cha komwe kulibe "makwerero" blur ndi akwaniritsa mawonekedwe mkulu khalidwe.
