3D Computer Graphics, Firimu, uye Zvose Zvakakosha Z-Axis
Kutsvaga 3D kakombiyuta mafirimu yekutanga, zvichida kuburikidza nekufarira mufirimu ye 3D, 3D maziso ekuonekwa , kana kubudiswa kwemifananidzo uye / kana mitambo yemavhidhiyo? Ichi ndicho chirevo chakafara ku 3D, saka ticharondedzera izwi mumutauro mukuru, tsanangura kuti rinopindirana sei nezvimwe zvinhu uye nenyaya dzepaiti ino, uye kukupa pfungwa yekutsvaga mamwe mashoko.
Saka, Chii chinonzi 3D?
Mutsanangudzo yakawandisa yezwi, 3D ingarondedzera chero chinhu chinowanikwa pane imwe nhatu yeCodeesian coordinate system. Kana izvozvo zvichitaura tad teknolojia, usatya - tichabva tazvichenesa pakarepo.
A Cartesian coordinate system inonyanya nzira inofananidzira kutsanangura X uye Y axes isu tose tinojaira kubva kuchikoro chesekondari (funga pepa re graph).
Iwe unorangarira kuita zvishoma madhifu nemasharu ane X axis ari yakanyatsojeka, uye Y axis iri kumira, yakarurama? Zvinhu zvakafanana zvikuru munyika ye 3D, pamwe chete-kune yechitatu yexisiti: Z, iyo inomiririra kukura .
Nokudaro netsanangudzo, chero chinhu chipi zvacho chinogona kuenzanisirwa pane matatu-axis system is 3D. Iyo haisi nyaya yose, hongu.
3D muIndaneti kuChirt Graphics
Mikana uri kuverenga izvi nokuti une rufaro rwekudarika muD 3D sezvo inotumidzwa mumashini yemashini yekombiyuta , iyo inosanganisira firimu, terevhizheni, kuparidzira, unyanzvi, nekugadzirwa kwevhidhiyo yemavhidhiyo.
Mamwe mashomanana anokosha pa 3D computer maikirwo:
- Tsanangudzo huru ye 3D space inogara yakangofanana: Zvinhu zvose pamusoro pe X, Y, uye Z-axis zvinoramba zvichiri zvechokwadi, asi kune imwe inobata. Kunyange zvazvo nyika chaiyo 3D zvinhu zvisikwa zviripo mumitambo mitatu, munyika ye digital yekombiyuta graphics 3D zvinhu zvinogona kungomiririra mashematically .
- 3D Models: Chero mumiririri wechinhu munzvimbo ye digital, inonzi 3D model . Kana iwe ukatarisa mashoko akajeka anowanikwa e- 3D model yemuenzaniso , zvingangove (kana kwete zvakadaro zvisiri) kuunganidza tsanangudzo dzematare dzinoratidza zviuru kana mamiriyoni ehutano hwakasiyana muCallesian space.
- Iyo software inoita masvomhu: Nenyaradzo kune vanyori, 3D software inosangana nematambudziko akawanda akaoma. Mukati pekushandiswa kwemashandisi ekushandisa ye 3D software package seVotodesk 3ds Max kana Maya , 3D mifananidzo inotsanangurwa uye inotaridzirwa inomiririrwa sezvinhu zve geometric zvakagadzirwa nemakona, maziso uye zviso zvepoloni. Zvose zvinowanikwa purogiramu yepurogiramu yakavakwa munguva chaiyo-inoita injini inokwanisa kuratidza mazamu eD 3D nemagetsi echokwadi, mashizha, uye mavara.
Zvimwe Pamusoro peZ-Axis:
Sezvo Z-axis isiri iyo inokosha inokosha ye 3D space, regai tinyatsocherechedza kuti "Z" inorevei chaizvo mumusangano we 3D software. Zoratidziro Z inogona kushandiswa kuyera zvinhu zvina mu 3D maikirwo emifananidzo:
- Kudzika kwechimwe chinhu maererano nehukuru. Sezviri mukati, maundi maviri akaenzana, mairi 4 marefu, uye maundi matatu akadzika .
- Nzvimbo yechinhu chinopesana nekwakabva. Kubva pane chero zviitiko zve 3D zviri (0,0,0) uye nhamba yechitatu kazhinji iri "Z". Kune zvishoma zviduku zviduku zve 3D zvinoshandisa Z seyero inotenderera, asi izvi zviitiko zvisingawanzoitiki.
- Nharaunda yechinhu kubva pane yakashandurwa kamera, inozivikanwa mumakombiyuta mafirimu se z-yakadzika. Z-Kuwedzera kunowanzoshandiswa kushandisa kuwedzera kwemazamu emigumisiro mumashure ekugadzirwa, uye mumitambo yemavhidhiyo inoshandiswa kuhuwandu hwehuwandu hwekugadzirisa.
- Z-axis of rotation . Semuenzaniso, bhora richibhururuka kubva kumera raizoti rinotenderera pamwe chete neZ negative axis.
3D muhukama neFirimu / Cinema:
Izwi rokuti 3D rinoreva chimwe chinhu chakasiyana zvachose kana chinoshandiswa mukutsvaga mafirimu e 3D (iyo inoda kuti iwe upfeke magirasi uye kuita kuti iwe ude kubuda kunze uye edza kubata zvinhu zvinobuda kunze kwekona). Mafirimu e 3D anokwanisa, uye anowanzoita, ane ruzivo rwe 3D mifananidzo yekombiyuta, zvisinei kuti pane zvakawanda zvemaitiro zvakapfura, kwete maCM mafirimu ayo akashandisa kuburitswa kwekudhindwa kwe 3D cinema.
Icho chirevo che "3D" sezvatinofunga pamusoro payo pafirimu yemafirimu (uye ikozvino muimba yemitambo ), ndeyekuti vateereri vemafirimu vanofanira kushandisa dzimwe nzira dzokunyengedza sviso revanhu rekuona kuva chirevo chisinganzwisisiki chekudzika.
- Binocular Disparity: Chinokosha pakuona kwepfungwa dzevanhu kune zvose zvinoita nekuti maziso edu anotumira chinyorwa chiduku zvakasiyana neuropi. Uropi hwedu hunoona mafungiro emaganhu kuburikidza nekududzira mutsauko mumufananidzo kubva kuruboshwe neziso rwerudyi. Izvi zvinozivikanwa se binocular disparity.
- Kukurukurirana kwakakwana kwekuti kufanana kweD 3D kunounzwa hupenyu kunogona kuwana nguva yakareba sei, uye iyi haisi iyo musangano yakakodzera. Tichakupa imwe tsanangudzo yekupedzisira, iyo inoshanda sechikonzero chekuti mafirimu e 3D anosikwa nhasi sei:
- Stereoscopy: Kuumba chinyorwa chekudzika, vaiti vemafirimu vakafanirwa kukudziridza nzira dzekufananidza kubvisa binocular . Nzira dzakawanda dzekuzadzisa izvi ndoshandisa nzira mbiri kana kushandura mafungiro ekugadzirisa pamwe chete nemakirasi anojekesa anovimbisa kuti ziso rakasara uye rakarurama rinogara richiwana mufananidzo wakasiyana. Izvi zvinozivikanwa se stereoscopy , saka izwi rokuti stereoscopic 3D .
Uye ikoko iwe unazvo!
Tinotarisira nehuse pano iwe unonyanya kuziva zvakawanda pamusoro peD 3D sezvo ichienderana nekombiyuta mafirimu nefirimu. Takapinda dzimwe hukama mumuviri wechinyorwa ichi, chinotsanangura mamwe mazano akaiswa mukudzika zvakadzama.
