Inkcazo ye-Antialiasing kwi-Gaming
Ukuguqulwa kwimifanekiso kunokuchazwa njengemizila yesiteji okanye iimijelo ezinje (ie jaggies ) ezisoloko zifumaneka kwiziboniso ezisezantsi. I-jaggies ibonakala ngenxa yokuba isilathisi okanye esinye isixhobo sokuvelisa asisebenzisi isisombululo esaneleyo sokubonisa umgca ogqithisiweyo.
Ulwaphulo-mthetho, ngoko-ke, iteknoloji enzame ukulungisa ukulungiswa kwezinto ezifunyenwe kumfanekiso (okanye nakwiisampuli zomsindo).
Unokufumana ukhetho lokulwa no-aliasing ukuba ukhangelelwa kwisetyuli somdlalo wevidiyo. Ezinye iinketho zingabandakanya i-4x, i-8x, kunye ne-16x, nangona i-128x inokwenzeka ngeenkqubo eziphambili ze-hardware.
Qaphela: Ulwaphulo-mthetho luvame ukubonwa njenge- anti-aliasing okanye i- AA , kwaye ngamanye amaxesha kuthiwa yi- oversampling .
Ulwaphulo-mthetho lusebenza njani?
Sibona imizila elula kunye nemigca ehlabathini lenene. Nangona kunjalo, xa unikezela imifanekiso yokubonakalisa kweso siqendu, zidilizwe zibe zizinto ezincinci zesikwele ezibizwa ngeephikseli. Le nkqubo ibangela imigca kunye neengcipheko ezivame ukubonakala zijonge.
Ukulwa ne-Antialiasing kunciphisa le ngxaki ngokusebenzisa isicwangciso esithile sokugqithisa imiphetho yomfanekiso jikelele ongcono. Oku kungase kusebenze ngokukhawuleza imida kuze kube yilapho ibonakala ilahlekelwa yiyo mgangatho. Ngokutshekisha iipekseli ngeenxa zonke, i-antialiasing iguqula umbala weepikseli ezijikelezayo, ukuxuba ukubonakala kwembonakalo.
Nangona ukuxuba kwepikseli kususa iingqamle ezibukhali, umphumo wokulwa nomonakalo ungenza ukuba iipikseli zifudesi.
Iintlobo zeeNkcazo zokuKhusela
Nazi ezinye iindlela ezahlukeneyo zobuchule bokulwa nokulwa:
I-Supersample Antialiasing (SSAA): Inkqubo ye-SSAA ithatha imifanekiso echanekileyo kunye neempendulo kumlinganiselo obalulekileyo. Oku kubangela ukugqithisa okulula, kodwa ukuphinda umgangatho wesidingo kufuna iimithombo ezininzi zeekhompyutha kwikhadi elibonisa imifanekiso, njengememori yevidiyo eyongezelelweyo. I-SSAA ayisetyenziswanga kakhulu ngenxa yokuba ifuna amandla amaninzi.
I-Multisample Antialiasing (MSAA): Inkqubo yesampula ye-MSAA idinga izixhobo ezincinci ngokuphinda uphakamise izinto kuphela zomfanekiso, ngakumbi iipolgoni. Le nkqubo ayikho nje inzixhobo ezinamandla. Ngelishwa, i-MSAA ayifani kakuhle kunye ne-alpha / transparent textures, kwaye ngenxa yokuba ayifaki isampula yonke indawo, umgangatho womfanekiso ungancitshiswa.
Ulwaphulo-mthetho olujongene ne-Adaptive Antialisation: Ukwandiswa kwe-AntiSAasing isandiso se-MSAA esisebenza kangcono nge-alpha / transparent textures kodwa ayithathi i-bandwidth kunye nezibonelelo zekhadi elibonisa imifanekiso ngendlela ephakamileyo.
I-Sampling Sampling Antialasing (CSAA): Uphuhliswe yi-NVIDIA, i-CSAA ivelisa iziphumo ezifanayo kunye ne-MSAA esemgangathweni kunye neendleko zokusebenza ezincinane kwi-MSAA.
I-EQAA yokuQinisekiswa koMgangatho (Quality Antialisation) (EQAA): Ephuhliswe yi-AMD kwiikhadi zemizobo yazo ye-Radeon, i-EQAA ifana ne-CSAA kwaye ihambisa i-antialiasing ephezulu ye-MSAA ngempembelelo encinci kwintsebenzo kwaye akukho mfuneko yememori yevidiyo.
Ukuxhatshazwa ngokukhawuleza okufutshane (FXAA): I- FXAA kukuphucula kwi-MSAA enokukhawuleza ngexabiso lentsebenzo elincinci. Ngaphezu koko, iguqula imida emfanekisweni wonke. Imifanekiso ene-FXAA antialiasing iyakuthi ibonakale ibonakala ngokugqithiseleyo, engenakunceda ukuba ukhangele imifanekiso eqingqiweyo.
I-AntiAracial Temporal (TXAA): I- TXAA yinkqubo yokuchasana entsha evelisa iziphumo eziphuculweyo kwi-FXAA ngokubandakanya iindlela ezahlukeneyo zokukhenkcela, kodwa ngeendleko zokusebenza eziphezulu. Le ndlela ayisebenzi kuwo onke amakhadi emifanekiso.
Indlela yokulungelelanisa i-Antialiasing
Njengoko kuchaziwe ngasentla, imidlalo ethile inika ukhetho phantsi kweefowuni zevidiyo, ukulungelelanisa i-antialiasing. Abanye banokunikela kuphela ngeendlela ezikhethiweyo okanye mhlawumbi bangakunikeli ukhetho lokutshintshela ukulwa nokulwa.
Unako kwakhona ukukwazi ukwenza izicwangciso ze-antialiasing ngokusebenzisa ipaneli yolawulo lwekhadi lakho levidiyo. Abanye abanye abaqhubi bezixhobo banokukunika ezinye iinketho zokuchasana ezingakhankanyiwe kule khasi.
Unokukhetha ukhetha ukuba unesigqeba sokulwa nesicatshulwa esichazwe yeso sicelo ukwenzela ukuba ukhetho oluthile lunokusetyenziswa kwimidlalo eyahlukeneyo, okanye unokuguqula ngokupheleleyo.
Yiyiphi i-Antialysis Setting Is Best?
Lo umbuzo onzima ukuwuphendula. Zama ngeempawu zekhadi kunye nemifanekiso yokubona ukuba zeziphi iindlela ozikhethayo.
Ukuba ufumana ukusebenza kuyancipha kakhulu, njengokunciphisa ireyithi zesalathisi okanye ubunzima bokulayishwa kwempahla, ukunciphisa izicwangciso zekhwalithi okanye uzame ukulwa ne-antialiasing.
Nangona kunjalo, khumbula ukuba ukhetho lwesimo sokulwa nesicatshulwa akusiyo imfuneko njengoko kwakusoloko kubakho ngenxa yokuba amakhadi amatshini aqhubekayo enza amagosa amatshini angcono kunye amasha anokwenza izigqibo eziqhelanisa ukuchithwa kwezinto ezininzi.
