FXAA - ntoni na? Indlela emlungisa. emlungisa imidlalo

Kuye ixesha xa umdlalo yayintle umdlalo wayo kuphela: Umdlali kwakudala baba bafuna yaye, ingakumbi, lifuna umgangatho eboniswe umfanekiso wekhusi. Kwangaxeshanye, bambalwa abantu bazi ukuba ukuze kuqinisekiswe ukuba kumgangatho ophezulu ekumgangatho namhlanje, abaphuhlisi ezininzi umdlalo sebenzisa FXAA isotfwe. Yintoni na - yaziwa namhlanje zonke nabadlala, kwaye abaninzi bacinga ukuba, ukuba kuyimfuneko ukuquka lo msebenzi.

Uninzi eyinhloko abadlali uyazi ukuba zenza ekuthiwa xitepisi emiphethweni bezinto, kwakunye nendlela ungenza ukuyisombulula le ngxaki ngokusebenzisa «anti-aliansing» okanye nje "ulungiso-olululo lobungakanani".

Yintoni ukuthandabuzwa?

Mpuluswa - oku into elungileyo, njengoko imbono ukwanda kakhulu lo mfanekiso, yaye izinto mihla le midlalo, apho awusetyenziselwa, ekugqibeleni ngakumbi kusenokwenzeka ukuba booed. Ngelo xesha sisahleli indlela enganelisiyo waqonda apho FXAA isotfwe. Ntoni na, abasebenzisi abaninzi bade babe nomdla, kodwa enyanisweni ngayo nokuphunyezwa kuchaphazela umgangatho kumfanekiso lokugqibela.

Ukuphunyezwa Poor kaninzi isizathu sokuba izixhobo ekujoliswe linamandla computing ayonelanga. Kakade ke, xa iimeko zivuma apha abo bakhetha ukudlala kwi PC, njengoko kulo mzekelo, umthamo wendawo yokucoca kwezixhobo kuxhomekeke ngqo kwi amathuba yemali umniniyo, kodwa console nabadlala badla sanele nje umdlalo, njengoko umgangatho ngemizobo abaninzi zamatyala kwiikhompyutha kakhulu ngcono xa kuthelekiswa noko ke imizobo imidlalo console. Noko ke, umntu ngamnye ukhululekile ukukhetha phi yaye yintoni umdlalo wakhe.

Yintoni FXAA?

Ngoko nangoko kufanele kuqatshelwe ukuba kakhulu ixesha igrodelov elide kusetyenziswa FXAA anti-olululo lobungakanani technology. Yintoni na, wayengazi ke, kodwa ukusetyenziswa kuqala ifumaneka MMO Age of Kwinan, ngokunjalo kwi edume lonke shooter ehlabathini LULOYIKO Ezi imidlalo, Noko ke, isetyenziswe kuphela yinguqulelo wokuqala ulungiso-olululo, ngelo xesha kwakukho ubambekile isisombululo yokusebenza.

Ekuhambeni kwexesha lethu kule midlalo sisebenzisa FXAA ifomati eyahlukileyo kancinci. Yintoni na? Imela ukuba zombini Fast omalunga Anti-olululo lobungakanani, nto leyo isisombululo kakuhle kakhulu xa kuthelekiswa MSAA technology yemveli. Oku single pixel yokupasa shader, apho kubangela isakhelo miscalculation kwenziwa kwinqanaba le post-processing. Le shader wadalwa ukuze sisombululo sikhawulezileyo, nto leyo ongafuni ekulondolozeni xa kuthelekiswa Kunye nokungentla, kodwa iingenelo ubuchwepheshe uhlawula umsebenzi, kwakunye nomgangatho. Ebona oku, abaninzi bacinga ukuba ubuchwepheshe awungeni ndawo. Enyanisweni oku akuyonyaniso.

Ziziphi iingenelo le ndlela?

Mpuluswa kwahlukile FXAA kwiqela lokulungileyo, kuquka uphuculo smoothing ekuthiwa subpixels, kunye specular. Igosa uxwebhu uTimoti Lotts we obu bugcisa ithi imveliso yakhe izicwangciso ezisemgangathweni medium kunye wenza post-processing lezakhelo ngokwesiseko yesisombululo 1920x1200 le GTX 480 ngesantya millisecond ngaphantsi kwesinye.

Inzuzo ephambili okuye ulungiso-olululo lobungakanani FXAA, akumi yintoni apha kusetyenziswa smoothing sub-pixels algorithm, nto leyo kakuhle kakhulu xa kuthelekiswa ne-MLAA algorithm, nto leyo kwanele ukuba ukusebenza izixhobo osebenza kwinqanaba DirectX9. Oko kukuthi, kulo mzekelo, i-processing sithuba eyenziwa kwindawo lokuphumelela enye, kwaye ezinomdla kakhulu ukuzimela ngokupheleleyo oko GPU Compute API. Noko ke, kukho kwakhona omnye ethile - nabaphuhlisi obu bugcisa kufuneka kubeka elungiselwe ezahlukeneyo imidlalo. Ngelo xesha, i zemveli technology anti-olululo lobungakanani isebenza okanye, phezu koko, awukwazi isebenze kwinqanaba umqhubi. Ngoko ke, lo gama badwelisi benkqubo ziya kusebenzisa kwinjini zabo indlela mpuluswa bomtya, yaye ngaloo ndlela uya kuba akayi kusetyenziswa zabo ikhowudi kwinjini FXAA, kuya kuba nzima ukufikelela ziphumo zinqwenelekayo, njengoko ithuba evela ngaphandle ikhowudi ukuba bekunokwenzeka de kutshanje.

ukuba le ngxaki isonjululwe njani?

Kwi ngokusebenzisa iqhosha [Misa] Ekuhambeni kwexesha, kwagqitywa ukuba okokuqala ukuqalisa FXAA ikhowudi d3d.dl kwithala leencwadi, nto leyo ithuba ulungelelwaniso bhetyebhetye kweziphumo ngokusebenzisa iifayile ezahlukeneyo uqwalaselo, kwakunye ukwenza okanye ukukhubaza lo FXAA. Le iseti lwefayile ekuqaleni zikhutshelwa kwi weefayili apho ifayile eliphunyeziweyo yi izicelo DX9 langoku, kwaye siqalo isicelo achole kwithala apho ikhowudi oluchanekileyo ekhoyo. Ngelo xesha, njengoko umbhekisi phambili ukuphunyezwa technology ka ikhowudi elayibrari uye ekuqaleni waqinisekisa ukuba iziphumo zomsebenzi babekwa log, inxaxheba abasebenzisi baqalisa ukuchonga bugs kule bugcisa, leyo wakulungisa. C Kwakhona "iinaliti" ziye wabonakala phezu ixesha ikhowudi ye iDirectX 10 kunye neefomathi 11.

Indlela ukuhlola?

Le nguqu icace kakhulu ukuqonda oko indlela kusetyenziswa mpuluswa bomtya kunye FXAA, kungaba in the World umdlalo Amatanki.

Ukuba FXAA anti-olululo lobungakanani lisusiwe, baqale ukubonisa enomahluko "ezizihambelayo", yaye nangona ukuba umfuziselo itanki kuba inkulu kakhulu kwaye ziya kwahluka iinkcukacha endilisekileyo, zakudala kubonakala kakhulu, ingakumbi ngokuphathelele iindidi zezinto ezingcakacileyo. eyakhelwe-anti-olululo lobungakanani yokuzoba uzama ngandlela thile ukuze nokuthambisa isixhobo elunxwemeni into, kodwa loo nto yenza ukuba lihle eliphakathi, singasathethi ke yinto yokuba mfanekiso maxa wambi ifiphale.

Yintoni utshintsho kwenzeka?

Xa watshintshela isixhobo FXAA, umphumo kucaca: ezenziwe ngesandla unyamalale ngokupheleleyo, kodwa kukho ezinye ungabe yomfanekiso. Ukongeza, kukho kwakhona uguqulelo unique FXAA Lola. technology umqambi in version elinye wongezelela ifildi yokuhluza, leyo wathathwa iMPC-HC, ngelixa iziphumo wokugqibela kakhulu ephucukileyo: Blur unyamalale ngokupheleleyo, indlela yokwenza zinhle kakhulu ngakumbi umbono ngaphezu yokuqala, yaye "somthamo", nangona ukusetyenziswa lokucoca phantse engekho ngokupheleleyo. Ngoku uyazi ukuba FXAA uhlobo in World of Amatanki umdlalo. Ngenxa yokuba ababhali abazange ekuqaleni izicwangciso ngoko ke ndikho ye ukuguda noburhabaxa kancinci ukuba "wakhuphe" wenqaba ende, kodwa umdlalo cishe ezingabonakaliyo.

Performance apha Oku hayi lifinyele. Kakade ke, World of Amatanki injini isebenza ngakumbi Akumangalisi ngoko iyazigqabhuza okanye, phezu koko, ukwehla yokusebenza ekugqibeleni ukuphuma nto.

NoAA, SMAA okanye FXAA

Xa sithelekisa iindlela «noAA» okanye SMAA kunye «FXAA Lola», umfanekiso uya kutshintsha kakhulu kuba ngcono kwimeko yokugqibela. Le ngaphandle kuphela apha le ukusetyenziswa yecebo endle leswaku linciphise ngokugqithiseleyo imigca zibhityile ngakumbi, ingakumbi, i oqaphelekayo ngokukodwa imvelaphi inyuselwa zokudubula emehlweni. Inani ngesekhondi FXAA ngobuwena yesibini ebenokudlula lwalo yangaphambili.

Iikhosi iimvavanyo ixesha elide, kwakugqitywa kwelokuba xa usebenzisa intsebenzo FXAA kuncipha malunga 10-12%, lo gama kwimeko xa usebenzisa indlela mpuluswa MSAA 4x, ogama umgangatho ikhuphisana namhlanje kunye nobuchwepheshe FXAA, aze sibonise nethontsi yokusebenza 50% okanye ngaphezulu.

Update

Ngo-2011, kananjalo kwabakho inguqulelo ngentando yakho ye isitofu, esibandakanya zonke iinketho ngasentla FXAA kunye iinzuzo zabo. Kule ndibano wawuzinyaswe eziliqela okucoca, phakathi esimelela out:

• Iimvakatjhi.
• Omuhle.
• Ukwanda umbala.
• YeSepia.
• Kunye nabanye abaninzi.

Konke oku Kulula kakhulu ukuba uqwalasele ngokusebenzisa yifayile eyodwa, kwaye kakhulu esiluncedo kulo mzekelo: i izicwangciso ngokulula itshintshwe, ngoxa zidlala, ukunciphisa nje isicelo, vula i Izicwangciso Umhleli, ukwandisa le app ukonwabele izicwangciso ezintsha ngaphandle kokuba iqale isicelo ukuba unomdla. Ngenxa yoko, kulwenze ukubeka ecaleni ngokupheleleyo ebunayo kamva kusebenze ekuloleni filter, ngokubonelela icace gca apho kungekho "somthamo" kweso yaye uphumelele noburhabaxa ezikumgangatho ophezulu.
