Incazelo ye-Antialiasing kumageyimu
Ukuguqula izithombe kungachazwa njengezinyathelo zezitebhisi zesiteji noma emaphethelweni ahlangene (okusho ama- jaggies ) avame ukutholakala ekubonisweni okuphansi. I-jaggies ibonakala ngoba i- monitor noma enye idivayisi yokukhipha ayisebenzisi isinqumo esanele kakhulu sokubonisa umugqa oshelelekile.
Ngakho-ke, ukulwa nokulwa, ubuchwepheshe obuzama ukuxazulula ukuguqulwa okutholakala esithombeni (noma ngisho nasesampula zomsindo).
Ungathola inketho yokulwa no-aliasing uma ubheka ngezilungiselelo zomdlalo wevidiyo. Ezinye izinketho zingabandakanya i-4x, i-8x, ne-16x, nakuba i-128x kungenzeka ngezimiso eziphambili ze-hardware.
Qaphela: Ukulwa nokulwa nokuvame ukuvame ukubonwa njenge- anti-aliasing noma i- AA , futhi ngezinye izikhathi kuthiwa yi- oversampling .
Ukuphikisana nokulwa nokulwa nokusebenza kusebenza kanjani?
Sibona imikhondo ebushelelezi nemigqa ezweni langempela. Noma kunjalo, lapho unikeza izithombe ukuze ziboniswe kumqapha, zidiliziwe zibe yizinto ezincane ezibizwa ngokuthi amaphikseli. Le nqubo iphumela emigqeni nasemigqeni evame ukubonakala ifakwe.
Ukulwa ne-Antialiasing kunciphisa le nkinga ngokusebenzisa inqubo ethize ukuze ibambelele emaphethelweni wesithombe esiphezulu esingcono. Lokhu kungase kusebenze ngokufiphaza kancane emaphethelweni aze abonakale elahlekelwa yilo mkhwalithi oyigugu. Ngokwesampuli zamaphikseli azungeze emaphethelweni, i-antialiasing ilungisa umbala wama-pixel azungezile, ihlanganisa ukubonakala okwenziwe.
Nakuba ukuxuba kwephikelli kususa imiphetho ebukhali, umphumela wokulwa nokulwa ungenza ama-pixels afinyelele.
Izinhlobo Zokukhethwa Kwama-Antialiasing
Nazi ezinye izinhlobo ezahlukene zezindlela zokulwa nokulwa:
I-Supersample Antialiasing (SSAA): Inqubo ye-SSAA ithatha izithombe eziphezulu zokuxazululwa kanye nezibonelo ezisezingeni elidingekayo. Lokhu kubangela ukuphequlula okulula kakhulu, kodwa ukuphrinta ngaphezulu kudinga izinsiza eziningi zehadiwe kusuka kwikhadi elihluzisayo, njengememori yevidiyo eyengeziwe. I-SSAA ayisetshenziswanga okuningi ngenxa yokuthi idinga amandla angakanani.
I-Multisample Antialiasing (MSAA): Inqubo yesampula ye-MSAA idinga izinsizakalo ezimbalwa ngokuphinda isetshenziswe kuphela izingxenye zesithombe, ikakhulukazi ama-polygoni. Le nqubo akuyona njengemithombo enamandla. Ngeshwa, i-MSAA ayisebenzi kahle nge-alpha / transparent textures, futhi ngenxa yokuthi ayisampuli sonke isimo, ikhwalithi yesithombe ingancishiswa.
Ukulwa ne-Antialasing Adaptive: Antialasing Adaptive isandiso se-MSAA esisebenza kangcono nge-alpha / transparent textures kodwa ayithathi i-bandwidth kanye nezinsiza zekhadi legrafu ngendlela ephakeme ngayo.
Ukuhlolwa kweSampling Antialiasing (CSAA): Kuthuthukiswe yi-NVIDIA, i-CSAA ikhiqiza imiphumela efana nekhwalithi ephezulu ye-MSAA ngezindleko ezimbalwa zokusebenza ngaphezu kwe-MSAA ejwayelekile.
Ukuqiniswa Kwezinga Lokunciphisa Ukulinganisa (EQAA): Kuthuthukiswe i-AMD ngamakhadi abo ehluzo e-Radeon, i-EQAA ifana ne-CSAA futhi ihlinzeka nge-high quality anti-antiasing nge-MSAA ngenomthelela omncane ekusebenzeni futhi akukho mfuneko yememori yevidiyo.
Ukunciphisa Okusheshayo Okusheshayo (i-FXAA): I- FXAA iyithuthukisa ku-MSAA esheshayo ngezindleko zokusebenza ezingaphansi kwe-hardware. Ngaphezu kwalokho, iqhubekela phambili emaphethelweni kuwo wonke umfanekiso. Izithombe nge-FXAA antialiasing, noma kunjalo, zingabonakala zizwakala kakhulu, ezingenakusizo uma ufuna ihluzo ezibukhali.
I-Anti-Aging Temporal (TXAA): I- TXAA yinqubo entsha yokulwa ne-anti-calification eyenza imiphumela ethuthukisiwe nge-FXAA ngokufaka amaqhinga amaningana e-smoothing, kodwa ngezindleko zokusebenza eziphakeme kakhulu. Le ndlela ayisebenzisi kuzo zonke amakhadi ezihluzo.
Indlela Yokulungisa Ukulwa nokulwa nokulwa
Njengoba kushiwo ngenhla, ezinye imidlalo zinikeza inketho ngaphansi kwezilungiselelo zevidiyo, ukulungisa i-antialiasing. Abanye banganikeza okukhethwa kukho kokubili noma kungenzeka bangakunikezi okukhethwa kukho ukushintsha i-antialiasing nhlobo.
Ungase futhi ukwazi ukwenza ngezifiso izilungiselelo zokulwa nokulwa ngephaneli yokulawula ikhadi lakho levidiyo. Abanye abashayeli bedivaysi bangakunikeza ezinye izinketho zokulwa nokungaziwa okukhulunywe ngazo kuleli khasi.
Ngokuvamile ungakhetha ukuba nezilungiselelo zokulwa nokulwa ezibekelwe uhlelo lokusebenza ukuze izinketho ezahlukene zingasetshenziswa emidlalweni ehlukene, noma ungavula ngokuphelele i-antialiasing.
Yikuphi Ukusekela Ukulwa Nezintambo Okuhle Kakhulu?
Lo akuwona umbuzo olula ukuphendula. Hlola izilungiselelo zekhadi legeyimu ne-graphics ukuze ubone ukuthi yiziphi izinketho ozikhethayo.
Uma uthola ukusebenza kunciphile kakhulu, njengokunciphisa amazinga ohlaka noma ubunzima bokulayisha izakhi, ukunciphisa izilungiselelo zekhwalithi noma uzame ukulwa ne-antialiasing encane kakhulu.
Noma kunjalo, khumbula ukuthi ukukhetha indawo yokulwa ne-antialiasing akudingekile njengoba kwakunjalo ngaphambili ngoba amakhadi ahluzo aqhubeka enza abaqaphi abangcono futhi abasha banenqumo eziqeda ukungafani okungaqondakali.
