Anisotropic Tātari. whakamahi Practical o ngā toronga: tātari anisotropic

tātari Anisotropic Ko tetahi o nga mea timatanga o whakairoiro hou, e hanga maha kaiwhakamahi ki te kōrero e pā ana ki te pehea i hanga e wātea ana he momo o te hangarau image whakarei ake mō ngā kaiwhakamahi i tenei ra.

Ehara i te mea e tika ana ki te huna i te meka e e mea faufaa ki gamers teie mahana te-kounga Runga Rawa whakairoiro e toru-ahu, a ko reira ratou te hunga i tenei ra e tata anake nga kiritaki momo katoa o hangarau hou i roto i te mara o kāri whakairoiro. I muri i te katoa, anake e taea te hiahiatia whakatere mana-tiketike i te kau i roto i te kaupapa e hiahia ana koe ki te whakahaere i etahi whakamutunga-whakatupuranga kēmu, i roto i nei i reira te tino tono pūkaha whakahaere shaders matatini o putanga rerekē.

He aha e mahere?

Mahi etahi pūkaha overdeveloped i roto i to tatou wa - he ururua nui o ngā rauemi he reira. A i te wa ano i te tūpono nui. Ēnei tikanga whakamahi anake kaupapa nui-pūtea ki te pānuitanga nui-tauine, i roto i mua, ara i mua i te tuku, māia e ka kia kaha tahia atu i te whata te kēmu. Hoki tuhipoka o ko te meka e i roto i nga tau tata nei tokanga makehe ki "tōrangapū" i runga i te pūkaha kēmu hou, no te mea i roto i te mara o te whanaketanga kēmu he wa roa i mua i reira ko te kaupapa here e pai ki te tango ki roto ki pūkete nga ngākau nuitanga o te kamupene ārahi e rua i roto i te mara o pūtukatuka whakairoiro - ko NVIDIA ko Ati.

Ko te kamupene i te wa roa whakataetae ki ia atu, a roto i te meka i reira he kore anga e i roto i te heke mai tata ka waiho reira taea ki te mutunga i te aroraa, engari ki kiritaki he reira anake i te ringa. Na ehara i te mea nui ki te whakawhanake i tētahi pūkaha tino-te kounga teitei, e hiahia ana hoki koe ki te haina i te tautoko o tetahi o nga hua, e ara whakaturia ake ratou ake hōtaka hononga mō igrodelov.

tupu te hōtaka, me te tupu ...

Hanga he uaua te revolution tino i roto i te mara o engines 3D-whakairoiro, kia he varavara enei takaí. Heoi, i roto i tenei take, o te akoranga, ake te kounga image te wā i runga i te wā, me te, piro nui, tupu te reira noa i raro i te putanga o etahi tino "hokona" kēmu rite Crysis.

Kei te hāngai te reira i runga i te tātari anisotropic, me te kawea pera-ka karanga anti-aliasing te i roto i tenei ra i te tuku o te tau nui o ngā atekōkiri ataata rerekē mō ia kaiwhakanao, me ia kamupene he ona ake huarahi me te kaupapa here e pā ana ki tenei arotautanga, i te mea tino maha tika he kore hoki te katoa.

He aha te mea tātari anisotropic?

Anisotropic Tātari - ko te tikanga motuhake o te whakapai ake i te kakano i runga i ngā mata e te hunga i te tetahi whanaunga koki ki te kāmera. Waihoki rite bilinear trilinear ranei, ka taea anisotropic ki te whakakore aliasing i runga i ngā mata rerekē, engari whakamōhio reira he iti o blurring, reira e pupuri te whakapakoko taipitopito haurokuroku.

E tano ia tapao e i roto i ngā kēmu whakatinanahia tātari anisotropic e te tikanga o te tātai uaua, ko te kupu whakarato i te "ore- raa" āhua iti o te tautuhinga i roto i te kēmu i kitea anake mai 2004.

I roto i te tikanga ki te matau te mea he tātari anisotropic, e hiahia ana koe ki te whai i etahi matauranga taketake i roto i tenei rohe. O te akoranga, i tenei ra matau ia kaiwhakamahi i titoa te mata e o te rota o pika rerekē, nei tau tei runga i te taumira tika. I roto i te tikanga ki te whakaatu i te whakapakoko i runga i whakairoiro mata ki te tukatuka i te tae o ia pika.

parau tumu o te mahi

Tīpakohia te kakano motuhake, e hāngai ana ki te taumira, kei nei i puta noa te aronga o te arotake. I muri i taua, e te reira he he torutoru texels haere te aronga mātakitaki, aru e wawaenga ratou tae.

Mai taea e te mata neke atu i te kotahi miriona pika, a kahore he ia Texel i roto i tenei take iti iho i te 32 paraire, e rapu kēmu tātari anisotropic kaha ataata hōkaiipurangi tino nui, e kore e nei whakarato tokomaha o ara nga whakaaro tino hou. Ko reira hoki tenei take e kua heke te taua whakaritenga mahara nui i roto i te whakamahi o te Keteroki, me te hangarau kakano kōpeketanga motuhake.

Pehea e mahi i te reira?

kawea faaotiraa o pika tae i roto i te tono ki te taparau kanokano image arā, o pika image ahu - texels, e kua superimposed i runga i 3D-mata. Ko te matawaenga matua i roto i tenei take, ko te rite te mea e whakatau texels te tae o te pika ki runga ki te mata. I roto i te tikanga ki te mahino pai te āhuatanga e wehewehe te tātari anisotropic, e hiahia ana koe ki te whakaaro te mea koutou mata - te reira i te umu nui, i runga i nei i reira te mea he momo nui o rua, ia o nei tohu te pika.

Hei whakatau i te tae o te pika ki runga ki te scene e toru-ahu i te mea i muri o te umu, he mea nui noa ki te titiro ki te poka hāngai. Na whakaaro e te kurupae marama e tika ana i reira, a ka whiwhi i runga i to tatou whenua, a ki te ka te tū te reira i roto i te whakarara ki te whakaaro ki o ratou wahi o te urunga, i roto i tenei take, te tiki i te wahi a tawhio o te marama. Ki te kore, te poke e kia ahua mio'i, ie. E kē E. he āhua porotītaha. taparau reira e kua whakanohoia i roto i te wahi marama, a ka whakatau i te tae o ia pika takitahi.

Te aha e mea e tika ana?

He tokomaha e whakapono e whakamahia te tātari anisotropic te anake i roto i te tikanga ki te whakarato image pai te kounga, engari i roto i te meka te reira noa te hua mutunga, whakaratohia e te he kore anake e tika ana ki te filtration ake.

A, no te hanga i te whakapakoko ngā hötaka kakano homai tātari kakano taumata-rua e whiriwhiringa tohu te iti me tawhiti mōrahi e whakatau i motuhake tātari mahi whakamahia te i roto i te tukanga o te hanga i te kakano whakapakoko i roto i te take, ki te te neke atu i te kāmera tata i te reira ranei.

Hei tauira, ka taea e tetahi whakaaro ka whakamahia trilinear anisotropic ranei tātari i roto i te āwhiwhitanga, i.e. ina tīmata ia Texel ki te whai ngā āhuatanga nui, me te kua hipokina pika maha. I roto i te tikanga ki te tango i roto i tenei aliasing āhuatanga, me te tātari i te reira e te whakamahi. Me kï reira e i roto i te āhuatanga i taua, ko te tawhiti atu tenei otinga i tino pai kia rite ki te tātari (anisotropic trilinear ranei) blurs te whakapakoko, he iti moka. I roto i te tikanga ki te hoatu i te tirohanga atu kiko o te pikitia, ka hiahia te whakanui ake i te taumira o te hanganga o.

Me pēhea ahau e whiriwhiri?

O te akoranga, i tetahi kaiwhakamahi me gamers noa i reira he tino he pātai arorau. I teie mahana i reira ko te tātari tri-rārangi me te anisotropic - he aha te pai? I roto i te meka, pai, o te akoranga, ko reira hangarau anisotropic. Ko te mea, ko te e kore ko te tino tika te tātari tri-rārangi Tātaitia te tae o ia Texel, a ki te waiho atu pau, e te reira he ki tona tumanako, ki te e korero tatou e pā ana ki rererangi hehema. hangarau anisotropic Taupānga taea tāpiritanga whakamahia i tēnei wā mō ngā aratau te tātari, te huri i te koki. Ko te kupu te nui te koki, te nui e waiho te kounga me te talena e he nehenehe o te whakarato tātari kakano anisotropic. Heoi, i te taua wa e ti'a ia tatou ia maramarama e, e tangohia ai me te maha nui o ngā kāri mō te mana tukatuka raraunga.

Pehea e tauturu te reira?

E kore e koe e mahara e iku, i muri i te whakaurunga o nga mahi whakairoiro e toru-ahu fabulously ake, ake noa i koki tiketike o te tetahi blurring whiwhi te, engari i roto i te hua whānui, whiwhi koe i te pikitia atu tūturu. I roto i tenei whakaaro, he utu ki te whakatau mehemea e whakamahi ia tenei me pehea e waiho ai hua hoki a ia nga tangata hoki ia.

Mai te whakapai ake rawa kaha i roto i te kounga o whakapakoko, e kore e tenei mahi whakarite e te hunga iwi e ngana ana ki te whakanui i te mahi o te kēmu i runga i te kore i te rorohiko kaha tino, titiro hoki pehea ki te mono tātari anisotropic. Titauraa o tenei mahi ko te incommensurate iti whakaritea ki te mea hua whakarato reira, na te reira e utu whakaaro e pā ana ki te pehea, ki te tahuri i te reira atu te tuatahi.

tīpako Point

Point tauira tohu i tenei ra i te whakatinanatanga tino ohie o te whakataunga te tae o te pika te. hāngai ana tēnei hātepe kei i runga i te whakapakoko kakano, ka tīpako i tetahi Texel kotahi, kei rite tata rite taea ki te pokapū o te wahi marama. Ehara i te mea uaua ki te imi e kore ko te tino tino pai te kōwhiringa taua, pera i te tae o te pika ki kia whakaritea te wā kotahi i texels maha, ka tīpakohia i roto i tenei take, kotahi anake, ka taea e te wahi marama huri ona āhua, e kore e tangohia e te hātepe ki pūkete.

Ko te drawback matua, āhuatanga nei taua tātari anisotropic, ko te meka e i pātata feunga tata ki te mata te maha o pika ka kia tino piki whakaritea ki te maha o texels, kia e kore te whakapakoko riro na ngā. Te pānga ārai pera-ka karanga o maha nuitia kitea i roto i te "tawhito" kēmu rorohiko.
