Ngesikhathi esifanayo, bambalwa abantu bazi ukuthi ukuze kuqinisekiswe izinga eliphezulu izinga namuhla, abaningi game Onjiniyela zisebenzisa FXAA antialiasing. Lokho kuyinto - waziwa namuhla akubona bonke abadlali, kanye eziningi kangaka ucabanga, ukuthi kubalulekile ukufaka lesi sici.

Iningi eyinhloko abadlali uyazi ukuthi bakha isitebhisi okuthiwa at emaphethelweni izinto, kanye nendlela ungakwazi ukuxazulula le nkinga ngokusebenzisa «anti-aliansing» noma simane 'anti-aliasing ".

Yini dithering?

Bushelelezi - lokhu iyisici ezinhle, njengoba umbono anda kakhulu yesithombe, futhi namaqiniso okuphila kwanamuhla we imidlalo, lapho alisetshenziswa, ekugcineni kungenzeka booed. Ngesikhathi esifanayo uhlala ngendlela abanelisi lapho beqaphela FXAA antialiasing. Ukuthi kuyini, abasebenzisi eziningi zingase zingazi nokwazi lingabi nesithakazelo, kodwa eqinisweni kuba ukuqaliswa kuthinta iqophelo isithombe sokugcina.

ngokuvamile ukuqaliswa Kubi yokuthi imishini kwelitshe has enganele amandla ama. Yiqiniso, e izimo ezikahle nazi labo abakhetha ukudlala kwi-PC, njengoba kulokhu, amandla we imishini encike ngqo kwi amathuba zezimali yomnikazi, kodwa console abadlala ngokuvamile okuqukethwe nje Gameplay, njengoba ikhwalithi ihluzo in iningi elikhulu amacala kumakhompyutha okuningi kangcono uma kuqhathaniswa lokho imifanekiso console imidlalo. Nokho, umuntu ngamunye ukhululekile ukuba akhethe kuphi nokuthi yini play wakhe.

Kuyini FXAA?

Ngokushesha kufanele kuphawulwe ukuthi impela eside isikhathi igrodelov esetshenziswa FXAA anti-aliasing ubuchwepheshe. Kuyini, angazanga ke, kodwa ukusetshenziswa lokuqala butholakala MMO Age of Conan, kanye encwadini edumile wonke UKWESABA emhlabeni Bhalobhasha Lezi imidlalo Nokho, wasebenzisa kuphela inguqulo yasekuqaleni anti-aliasing, ngaleso sikhathi kwaba hhayi kakhulu isixazululo ukusebenza.

Esikhathini sethu kule imidlalo sisebenzisa ukuhluka format FXAA. Kuyini lokhu? Elikumelelayo kokubili okusheshayo eseduze Anti-Aliasing, okuyinto yisisombululo esiphumelela nakakhulu lapho kuqhathaniswa bendabuko ubuchwepheshe MSAA. Lokhu olulodwa pass kwe-pixel shader, lapho kwaphumela Uhlaka miscalculation eyenziwa ngaso esigabeni post-ukucubungula. Lokhu shader wadalelwa ukuba abe esisheshayo, okuyinto bafune kwisitoreji ngokuziqhathanisa ngenhla, kodwa izinzuzo ubuchwepheshe okhokhela umsebenzi, kanye izinga. Ebona lokhu, abaningi bangase bacabange ukuthi ubuchwepheshe asihlobene. Empeleni lokhu akulona iqiniso.

Yiziphi izinzuzo le ndlela?

Bushelelezi kuyahluka FXAA eziningi eziwusizo, kuhlanganise ngcono bushelelezi okuthiwa subpixels, futhi specular. Isikhulu idokhumenti Thimothewu Lotts kunjiniyela lobu buchwepheshe uthi umkhiqizo wakhe nge izilungiselelo naphakathi izinga wenza post-ukucutshungulwa ozimele ngesisekelo isinqumo 1920x1200 le GTX 480 ngesilinganiso engaphansi kweyodwa amasekhondi amancane.

Izinzuzo main ukuthi ine anti-aliasing FXAA, aqukethe kulokho elisetshenziswe lapha bushelelezi algorithm sub-pixel, okuyinto iyashelela eqhathaniswa MLAA algorithm, okuyinto ngempela eyanele for ukusebenza imishini eyehlayo on DirectX9 ezingeni. Lokho, kulesi simo, iposi ukucubungula wenziwa pass olulodwa, futhi ezithakazelisa kakhulu iyona ukuzimela ngokuphelele kulokho kusetshenziswa i-GPU yekhompyutha API. Nokho, kukhona omunye ethile - Onjiniyela lobu buchwepheshe kumelwe nakanjani ukuba kugxiliswe ezihlukahlukene imidlalo. Ngesikhathi esifanayo, bendabuko anti-aliasing ubuchwepheshe isebenza noma, kunalokho, awukwazi ukusebenza ezingeni umshayeli. Ngakho, nakuba ngokungangabazeki program izosebenzisa e izinjini zabo indlela bushelelezi lomchazi, futhi ngaleyo ndlela ngeke isetshenziswe ikhodi yabo izinjini FXAA, kuyoba kungenzeki ukufeza nomphumela ofiselekayo, njengoba aphenduke ngaphandle ikhodi kwakungenakwenzeka kuze kube muva nje.

inkinga isixazululekile kanjani?

On usebenzisa inkinobho [Pause] Ngokuhamba kwesikhathi, kwanqunywa ukuba ekuqaleni ukwethula FXAA ikhodi d3d.dl wezincwadi, okuholela ithuba ukulungiswa nezimo kwemiphumela ngokusebenzisa amafayela ahlukahlukene ukucushwa, kanye vumela noma vimbela FXAA. Lokhu yamafayela ekuqaleni ukopishelwe lwemibhalo lapho ifayela elisebenzisekayo likhona izicelo DX9, futhi sokuqalisa isicelo ziyoyizwa umtapo lapho ikhodi efanele likhona. Ngesikhathi esifanayo, njengoba unjiniyela ukuqaliswa ubuchwepheshe ikhodi wezincwadi ekuqaleni, waqiniseka ukuthi imiphumela umsebenzi babekwa lwamakholi, abasebenzisi ngenkuthalo waqala ukuhlonza izimbungulu lobu buchwepheshe, alungise ngokushesha. C futhi "imijovo" avele esikhathini ikhodi IDirectX 10 no-11 nezakhiwo.

Kanjani ukuhlola?

Umthelela osobala kakhulu ukunquma ukuthi indlela isetshenziswa bushelelezi lomchazi futhi FXAA, kungaba umdlalo World of Tanks.

Uma FXAA anti-aliasing alisetshenziswa, baqale ukukhombisa abahlukene "esizihambelayo", futhi naphezu kweqiniso lokuthi imodeli ithangi kungaba mikhulu futhi kuzohluka ngokuningiliziwe ehloniphekile, zobuciko avele kakhulu, futhi ikakhulukazi maqondana ezihlukahlukene lezinto mncane. esakhelwe anti-aliasing amasu uzama ngandlela-thile ukuze gcoba emaphethelweni lwento, kodwa kwenza kube kuhle Okuqukethwe akuzwakali, ingasaphathwa lokuthi isithombe Ngezinye izikhathi kungase anyakaza.

Iziphi izinguquko zenzeka?

Uma ushintshele FXAA ithuluzi, umphumela kuba sobala: izinto ezenziwe ngesandla zinyamalale ngokuphelele, kodwa kukhona abanye Ukufiphalisa yesithombe. Ngaphezu kwalokho, kukhona futhi inguqulo eyingqayizivele FXAA Lola. ubuchwepheshe kunjiniyela kwelinye okufushane ungeze ensimini lemifanekiso, okuyinto sathathwa MPC-HC, kuyilapho umphumela wokugcina kwaba ngempela ehloniphekile: ilensi zinyamalale ngokuphelele, ukwakheka ishaqisa nakakhulu umbono kuka original, kanye "isitebhisi", naphezu ukusetshenziswa ukuhlunga iyivelakancane ngokuphelele. Manje ngoba sewuyazi ukuthi hlobo luni lwe FXAA e World of Tanks umdlalo. Ngenxa yokuthi abalobi akazange ekuqaleni kuhlelwe ngakho nokucija ukuthungwa kungenzeka kancane "knock out" umbhoshongo, kodwa Gameplay cishe ezingabonakali.

Ukusebenza lapha cishe hhayi ziyancipha. Yiqiniso, World of Tanks injini isisebenza Yingakho-ke liqhumise noma, kunalokho, kwehla ukusebenza angagcina ukuphuma lutho.

NOAA, SMAA noma FXAA

Uma siqhathanisa izindlela «NOAA» noma SMAA futhi «FXAA Lola», isithombe zizoshintsha kakhulu ngenxa kangcono mBhalo. Okuwukuphela lapha ukusetshenziswa isihlungi ensimini ukuthi unciphise ngokweqile imigqa mncane nakakhulu, ikakhulukazi, ephawuleka ikakhulukazi ukukhwezwa wezikhali emehlweni. Isibalo ozimele ngesekhondi samuntu FXAA kuzidlula samuntu odlule.

Ngokuhamba ukuhlolwa eside, kwatholakala ukuthi uma usebenzisa FXAA ukusebenza kuncipha ngamaphesenti angaba ngu 10-12%, kanti esimweni lapho usebenzisa indlela bushelelezi MSAA 4x, ogama izinga kuphazanyiswa namuhla FXAA ubuchwepheshe, futhi enza ubonakalise iconsi ukusebenza 50% noma ngaphezulu.

Buyekeza

Ngo-2011, kwaba khona inguqulo ngokwezifiso lomjovo, eyayihlanganisa zonke okungenhla ongakhetha FXAA kanye nezinzuzo zabo. Kulesi inhlangano yahanjelwa eziningana impela izihlungi, phakathi okuyinto ivelele:

• Ilensi.
• Vignetting.
• ukugcwaliswa umbala.
• Sepia.
• Kanti abanye abaningi.

Konke lokhu Kulula kakhulu ukumisa ngokusebenzisa kufayela elilodwa, futhi ewusizo kakhulu kulokhu: izilungiselelo kungenziwa kalula ushintshe, ngisho ngenkathi idlala, umane ukunciphisa isicelo, vula Izilungiselelo Umhleli, ukunweba uhlelo lokusebenza futhi ujabulele izilungiselelo ezintsha ngaphandle kokuthi uqale kabusha uhlelo lokusebenza ukuthi unesithakazelo. Ngakho-ke, kuye kwavela aluqede ngokuphelele lantambama kamuva kusebenze imimese lemifanekiso, ukuhlinzeka isithombe esicacile lapho azikho "isitebhisi" ukufiphaza futhi izuzwe high quality ukwakheka.
