I ka Ia manawa, mau kanaka ike i ka mea e hōʻoia i ka kiʻekiʻe kiʻekiʻe o ka mea e like ai i kēia lā, he nui hihiu haku polokalamu hoʻohana FXAA antialiasing. He aha ka mea, mea - ua ike i keia mea i pau gamers, a no laila, he nui ke aloha, ina paha he mea e pono ke loaʻa i kēia hiʻona.

Ke predominant hapanui o na âlapa pôhili me ua ike e lakou i ka ai-kapa hulili ma na kihi o ka mea, e like me peheaʻoe ke hoʻoponopono i kēia pilikia ma ka hoʻohana 'ana i ka «Anati-aliansing» ole wale "Anati-aliasing".

I ka Ia manawa koe unsatisfactory ala ma i ike FXAA antialiasing. He aha ia mea, he nui na mea hoʻohana i ole hoi e hoihoi, akā, ma ka mea ka mea, o ka manaʻo e loli ai i ka pono o ka mea hope loa kiʻi.

Ilihune manaʻo He pinepine ke kumu i ka pale umauma hoʻokahi ipu he lawa Me ka mana. O ka hana ana, ma ke 'ano kūpono' aneʻi e ka poe i makemake e paani ma ka PC, me ia ma keia hihia, ka 'auhau o ka ipu mea pololei e kaukaʻi ma na nā papaha kālā o ka mea nana ka waiwai, akā, hooluolu mai gamers pinepine maʻiʻo me pololei ka gameplay, like me ka mea e like ai i nā kiʻi o loko o ka hapanui nui o nā hihia ma kamepiula' ē he nui maikaʻi hoʻohālike au ia mea i nā kiʻi i hooluolu mai ia lealea. Eia naʻe, kēlā kanaka mea noa e koho i kahi a me ka mea i kona hula.

He aha ka FXAA?

Koke ia e ke kaulana i ka hala loa o ka lōʻihi manawa igrodelov hoʻohana FXAA Anati-aliasing enehana. He aha ka mea, i ole i laila, akā, i ka mua ana ka mea, ua loaʻa i loko o MMO Age o Anohana, e like me ia ma ka kaulana a pau ma luna o ka honua poʻe makaʻu kēia mau lealea, nae, wale ka mua kēia o ka Anati-aliasing, a ma ia manawa ua he ole loa i hoʻohana lawelawe pāʻoihana.

I ka manawa i loko o nā pāʻani mākou hoʻohana he iki okoa waihona FXAA. He aha ka mea? Ia ihola ke kumu no nā Fast He kokekau wale Anti-Aliasing, a mea he nui ka hoʻokō pāʻoihana like like me ka loina 'enehana MSAA. He hookahi alahele kiʻi kiko shader, ai ka kūpono maoli miscalculation hana ma ke kahua o ke kia-aaioee. Kēia shader Ua hanaia me ke ola Lokomaikaʻi, mea i emi, ua koi ikaika ma waho pūnaewele i loko o e like me ka mea ma luna, akā, no ka pono o ka 'ike loea hou uku i ka hana, e like me kona mea e like. No keia, he nui manaʻo i i ka 'enehana mea pili' ole. I mea keia mea i oiaio.

He aha nō i ka pono o keia hana?

Smoothing kekahi FXAA i ka helu o ka pono, a me hou smoothing ai-kapaia subpixels, a me ka specular. An kūhelu palapala Timoteo Lotts nā mea haku polokalamu o kēia 'ike loea hou mai nei i kona huahana me ka meakino e like ai ka hoʻopaʻa' ana hanaʻia kia-aaioee o nā mōlina ma luna o ke kumu o ka olelo hooholo o 1920x1200 ka GTX 480 i ka uku o ka emi o kekahi millisecond.

I ka papa kuhikuhiE pomaikai i loaʻa Anati-aliasing FXAA, iloko ka mea ua 'aneʻi hoʻohana smoothing algorithm iiaciiie-nā kiko kiʻi, i mea oi efficient hoohalikeia me ka MLAA algorithm, i mea nō e pono ai no ka hana o ka ipu e holo ma luna o DirectX9 pae. I ua, ma keia hihia, i ka lāʻau kū-aaioee ua lawe mai i loko o ka hookahi alahele, a me ka loa hoihoi 'o ka piha kuokoa mai GPU Compute API mea i hoʻohana. Eia naʻe, he mea no hoi kekahi drawback - pono pono e i loko iho na haku polokalamu o kēia 'enehana ma ka likeʻole ma o nā pāʻani. I ka Ia manawa, kahiko Anati-aliasing enehana ka hana paha, ma ka mea ku ole, hiki ole hana ma ka Keaukaha pae. Penei, oiai programmers e hana i loko o kā lākou mau kiko'ī ano o exponential smoothing, a pela e ole e ia i loko o kā lākou mau kiko'ī FXAA kivila, ka mea e e 'ole ke hoʻokō i ka makemake hookoia, e like me ka huli, mai waho mai o ka kivila mai hiki ua ole a nei.

Pehea i ka pilikia Wehewehe i nā hāʻina?

Ma ka hoʻohana 'ana i ke pihi [kakali] Over manawa, ka mea i hoʻoholo i initially hoʻolauna FXAA d3d.dl kivila i loko o ka hale waihona puke, kūpono ma ka manawa o ka'ōlewa hoʻoponopono o nā hualoaʻa ma nā hoʻonohonohoʻia AEIU, e like me ka ho'ā a hoʻopio i ka FXAA. Kēia 'ia paha o nā AEIU mua mānewanewa kanikau a hiki i ka papa kuhikuhi ma ka executable waihona mea keia DX9 palapala noi, me ka noi mea hoʻomaka e koho i ka hale waihona puke ma i ka pololei kivila mea i loaʻa. I ka Ia manawa, e like me ka mea haku polokalamu o ka 'ike loea hou hoʻokō' ana o ke karaima i loko o ka hale waihona puke i kope i paa i ka hopena o na hana i kau ia ma ke kaola, hoʻohana 'Imi hoʻomaka' ana e kuhikuhi i pilikia i loko o kēia 'ike loea, a koke ee a. C mea hoi "injections" Uaʻikeʻia ma manawa me ka code for Na DirectX 10 a me 11 kūmole.

Pehea e nānā?

Ka loa ahuwale ia mea e hooholo ka papa hana ua hoʻohana 'exponential smoothing a me ka FXAA, hiki ia i loko o ka laua World o ka poʻina nalu.

Inā FXAA Anati-aliasing ua ole ia, hoʻomaka e hōʻike okoa "escalator", a me ka hoʻowahāwahā i ka mea i ka pahu kŘkohu hiki e loa ai nui, a E oko a kohu kūpono au mamuli, artifacts hōʻike he nui loa, a oi loa aku hoi me ka mahalo i keʻano o ka lahilahi mea. kukulu-i loko o Anati-aliasingʻano hana ua ho'āʻo ana ma kekahi ala e lubricate i ka lihi o ke kiʻi, akā, e hana ia nani mediocre,ʻaʻole e hōʻike i ka mea i i kekahi manawa i ke kiʻi e blurred.

He aha hoʻololi i hoʻomaka ai?

Once ua hō'ā FXAA koʻi lipi, o ka hopena i mōakāka: na artifacts nalo loa, akā, he mea kekahi blurring o ke kiʻi. Eia hou kekahi, he mea no hoi he kū hoʻokahi mana FXAA ka hoʻokala i. enehana nā mea haku polokalamu i loko o kekahi mana hou i ka Kānana kahua, a i laweʻia, mai MPC-HC, oiai o ka hopena hope ua hala loa kohu kūpono: blur loa nalo, textures nei ka 'oi hana keaka nānaina ma mua o ke kiʻi, a me ka "hulili", hoʻowahāwahā i ka waiwai o ka ka Kānana ua kokoke loa kahi e. Ano, i ko oukou ike ana i 'ano FXAA ma World o ka poʻina nalu hihiu. Aie i ka mea i na kākau i i mua? Oaony no laila, i ka oi ana o ka hionapāʻili hiki iki "kikeke mai" o ka hale kiai, akā, me ka gameplay ia meaʻaneʻaneʻike makaʻole.

Ua kokoke i hoemi Auana 'aneʻi. O ke ala, World o ka poʻina nalu engine hana hou surprisingly, no ia mea, o poha paha, ma ka mea ku ole, ka hana ana emi ana e ho'ōla i uē helu mai o ka ole.

Noaa, SMAA a FXAA

Inā ka 'ole «Noaa» a SMAA a «FXAA hoʻokala» kakou e hoakaka aku, i ke kiʻi e hoʻololi me ka nui loa no ka mea maikaʻi i loko o ka hope hihia. Ke wale koe naeʻaneʻi o ka hoʻohana 'ana o ke kula Kānana e narrows excessively lahilahi laina a hiki aku, i ka maikai, i oi loa aku hoi kekahi' i lele kaua mau maka. Ka helu o nā mōlina no kekonaʻano FXAA nui aku i ka muaʻano.

Ma ka papa o ka lōʻihi-makahiki ho'āʻo ma, ka mea i manao i ka wā hoʻohana FXAA hana paka ua ma kahi o 10-12%, oiai i loko o ka hihia ma ka wā o ka smoothing ano MSAA 4x, o kona mea e like ai paʻi i keia la me ka enehana FXAA, a hana hoike i ka hana kulu 50% a oi.

Kiʻi hou

I ka 2011, he ua no hoi he customizable hoʻokolohua o ka ka pahu kui, a komo a pau o ka mea ma luna o nā koho i FXAA a me kā lākou mau ia e pōmaikaʻi ai. I kēiaʻaha kanaka i hele ma muli o kona kulana i ka helu o nā kānana, i waena o i ku mai:

• Blur.
• Vignetting.
• waihoʻoluʻu saturation.
• Sepia.
• A he nui 'ē aʻe.

A pau i kēia mea nō oluolu e kele pūnaewele ma ka hookahi apuapu, a me ka loa pono keia mau mea i loko o keia hihia: na palapala koho hiki ke hoopuni hoʻololi, a hiki i ka wa hookani, wale loa kń i ke noi, e hoʻokaʻakaʻa aʻeʻoe i ka palapala koho Lunahooponopono, hoʻonui i ka mail app, a nanea i ka hou palapala koho me ka loaa e hō'ā i ka noi ana au e pili. Penei, ka mea, ua i huli loa hoʻopau mae wale ma hope ho'ā hoʻi heʻoiʻoi Kānana, ina he clearer kiʻi o kahi o nā ole "hulili" blur a loaʻa kiʻekiʻe ma Hawaiʻi textures.
