3D Computer Graphics, Mafilimu, ndi Z-Axis Zonse Zofunikira
Kufufuza zithunzi za pakompyuta 3D nthawi yoyamba, kaya mwa chidwi ndi filimu ya 3D, 3D zowonetseratu , kapena kupanga zojambula ndi / kapena masewero a kanema? Ichi ndi chiwonetsero chachikulu cha 3D, kotero tidzatha kufotokozera mawuwo mwachidule, kufotokoza momwe zimagwirizanirana ndi zida ndi zolemba pa tsamba ili, ndikupatseni lingaliro la momwe mungafunire zambiri zambiri.
Kotero, Kodi 3D ndi chiyani?
M'mafotokozedwe ochuluka kwambiri a mawuwo, 3D ingafotokoze chinthu chilichonse chomwe chikupezeka pa dongosolo lokonzekera lamakono la Cartesian. Ngati izo zikumveka ngati zamakono, usawope - tidzasiya izo nthawi yomweyo.
Makhalidwe a Cartesian ndi njira yabwino kwambiri yofotokozera zida za X ndi Y zomwe timadziwidziwa kuchokera ku sukulu ya sekondale (taganizirani pepala la graph).
Mukukumbukira kupanga ma grafu ndi masatidwe pang'ono ndi X axis pokhala osakanikirana, ndipo Y yothandizira ikuwoneka, molondola? Zinthu ndi zofanana kwambiri pa dziko la 3D, ndi zosiyana - pali mbali yachitatu: Z, yomwe imayimira kuzama .
Kotero mwakutanthawuza, chinthu chirichonse chomwe chingakhoze kuimiridwa pa dongosolo la atatu-axis ndi 3D. Iyi si nkhani yonse, ndithudi.
3D mu Zogwirizana ndi Mafilimu a Mafilimu
Mwayi mukuwerenga izi chifukwa muli ndi chidwi chodabwitsa ku 3D monga momwe zimatchulidwira mu makina opanga makompyuta , omwe akuphatikizapo mafilimu, televizioni, malonda, malingaliro, ndi chitukuko cha masewera a kanema.
Mfundo zazikulu zochepa pa zithunzi za pakompyuta 3D:
- Kutanthauzira kwakukulu kwa danga la 3D kumakhala chimodzimodzi: Zonse zokhudza X, Y, ndi Z-axis zikugwirabe zoona, koma pali nsomba imodzi. Pamene dziko lenileni zinthu za 3D zimakhalapo mu miyeso itatu, mu dziko ladijito la makompyuta zithunzi za 3D zikhoza kuimiridwa masamu .
- Zithunzi za 3D: Chifaniziro chirichonse cha chinthu mu dera la digital, chimatchedwa 3D model . Ngati mutayang'ana mfundo zofiira zomwe zimaphatikizapo mtundu wa 3D , zingangokhala (kapena osati mophweka) kuti zikhale zolemba zomwe zikuwonetsera masauzande kapena mamiliyoni a makonzedwe osiyana mu malo a Cartesian.
- Pulogalamuyi imakhala ndi masamu: Mwachangu kwa ojambula zithunzi, 3D mapulogalamu amachititsa masamu ambiri ovuta. Pogwiritsa ntchito mawonekedwe a 3D mapulogalamu monga Autodesk 3ds Max kapena Maya , 3D zitsanzo zimatembenuzidwa ndikuwonekera poyera ngati zinthu zamagetsi zomwe zimapangidwa m'mphepete, mazenera, ndi nkhope zapoloni. Mapulogalamu ambiri a mapulogalamu amanga mu nthawi yeniyeni yopanga injini yomwe imatha kuwonetsera zitsanzo za 3D ndi zowala zenizeni, mithunzi, ndi maonekedwe.
Zambiri pa Z-Axis:
Popeza Z-axis ndi khalidwe lofunika kwambiri la danga la 3D, tiyeni tiwone zomwe Z "Z" zimatanthawuziradi mu malo a 3D mapulogalamu. Z zogwirizanitsa Z zingagwiritsidwe ntchito poyeza zinthu zinayi mu 3D makanema ma PC:
- Kuzama kwa chinthu mwa kukula kwake. Monga momwe, maunite asanu akulira, maunite 4 ataliatali, ndi magawo atatu akuya .
- Malo a chinthu chogwirizana ndi chiyambi. Chiyambi cha chinthu chilichonse cha 3D ndi (0,0,0) ndi nambala yachitatu kawirikawiri kukhala "Z". Pali mapepala ang'onoang'ono a 3D omwe amagwiritsa ntchito Z monga zowonongeka, koma milanduyi ndi yosawerengeka.
- Mtunda wa chinthu kuchokera pa kamera yotembenuzidwa, yomwe imadziwika pamakompyuta monga z-kuya. Z-Depth nthawi zambiri amagwiritsidwa ntchito kugwiritsa ntchito kwambiri zotsatira zapangidwe kumapeto kwa kupanga, ndipo m'maseĊµera a pakompyuta amagwiritsidwa ntchito pazomwe zimakhazikitsidwa mwatsatanetsatane.
- Z-axis of rotation . Mwachitsanzo, kuthamanga mpira kuchoka pa kamera kunganenere kuti ikuzungulira pa Z-axis yolakwika.
3D poyerekezera ndi mafilimu / mafilimu:
Mawu 3D amatanthauza chinachake chosiyana kwambiri ngati chikugwiritsidwa ntchito ponena za mafilimu a 3D (mtundu womwe ukufuna kuti muzivala magalasi ndikukupangitsani kuti muyesetse kuyesetsa kuti muzitha kukhudza zinthu zomwe zikuchokera pazenera). Mafirimu a 3D akhoza, komanso nthawi zambiri, amakhala ndi zithunzi za 3D makompyuta, komabe pali mafilimu ambiri omwe sakhala a CG omwe agwiritsanso ntchito mafilimu a 3D.
Kufotokozera za "3D" monga momwe timaganizira pa filimu ya mafilimu (komanso panopa kumaseĊµera a nyumba ), ndi kuti ojambula mafilimu ayenera kugwiritsa ntchito njira zina zokhotetsa kayendedwe kabwino kaumunthu kukhala chiwonetsero chachinyengo chozama.
- Binocular Disparity: Chinsinsi cha kulingalira kwakukulu kwa umunthu chiri ndi chirichonse chochita ndi mfundo yakuti maso athu amatumiza chithunzi chosiyana kwambiri ndi ubongo. Ubongo wathu umakhala ndi malingaliro a mtunda mwa kumasulira kusiyana mu fano kuchokera kumanzere ndi kumanja komwe. Izi zimadziwika ngati kusiyana kwa binocular.
- Kufotokozera kwathunthu za momwe chiwonetsero cha 3D chimapangidwira kukhala moyo chingatenge nthawi yaitali, ndipo iyi si yoyenera. Tidzakupatsani tanthawuzo limodzi lomaliza, lomwe limakhala ngati maziko a momwe mafilimu a 3D alili lero:
- Zojambulajambula: Kuti apange chinyengo cha akuya, opanga mafilimu akuyenera kukhala ndi njira zotsanzira kusiyana kwa binocular . Njira yodziwika popindulira izi ndi kugwiritsa ntchito mawonekedwe awiri kapena osakaniza pogwiritsa ntchito magalasi omwe amachititsa kuti diso lamanzere komanso lamanja likhale ndi chithunzi chosiyana. Izi zimatchedwa stereoscopy , motero mawu otchedwa 3D stereoscopic .
Ndipo apo muli nacho icho!
Tikukhulupirira kuti apa ndiwe wodziwa zambiri za 3D momwe zikukhudzira mafilimu ndi mafilimu. Taphatikizapo maumboni ena mu thupi la nkhaniyi, lomwe likufotokozera zina mwa mfundo zomwe zafotokozedwa mozama.
