3D Computer Graphics, Zaj duab xis, thiab Tag Nrho Tseem Ceeb Z-Axis
Tshawb kawm txog 3D lub computer graphics rau thawj zaug, puas yog los ntawm kev nyiam ua yeeb yaj kiab, 3D nrig txog teeb meem , los yog ntau lawm rau cov animation thiab video games? Qhov no yog cov lus qhia dav dav rau 3D, yog li peb yuav txhais cov ntsiab lus nyob rau hauv ib qho kev txiav txim siab zoo, piav qhia txog nws txoj haujlwm thiab cov khoom hauv lub vev xaib, thiab muab ib lub tswv yim rau qhov twg los nrhiav qhov kev qhia ntxiv.
Yog li, Dab tsi yog 3D?
Hauv qhov dav txhais lub ntsiab lus, 3D yuav piav txog yam khoom uas tshwm sim ntawm peb txoj kab Cartesian coordinate system. Yog hais tias lub suab tad ib qho, tsis txhob ntshai - peb mam li tshem nws tam sim ntawd.
Lub Cartesian coordinate system yog ib txoj kev zoo txog kev piav qhia txog X thiab Y-axes peb txhua tus paub txog cov tsev kawm ntawv qib siab (xav daim duab).
Koj nco ntsoov ua cov duab me me thiab cov kab kos nrog X axis yog kab rov tav, thiab Y axis ua ntsug, txoj cai? Tej yam uas muaj ntau heev hauv lub ntiaj teb 3D, nrog rau ib qho kev tshwj xeeb - nws muaj ib qho xiav thib peb: Z, uas sawv cev qhov tob .
Yog li los ntawm txhais, tej yam khoom uas tuaj yeem sawv cev rau hauv peb lub cev yog 3D. Qhov no tsis yog tag nrho zaj dab neeg, tau kawg.
3D hauv kev sib raug zoo rau Computer Graphics
Koj muaj peev xwm nyeem tau qhov no vim tias koj muaj tsawg kawg yog ib qho paj hauv 3D raws li nws raug xa mus rau hauv kev lag luam hauv computer graphics , uas muaj movies, TV, advertising, engineering, thiab kev ua si hauv video.
Ob peb qho tseem ceeb ntawm 3D lub computer graphics:
- Lub ntsiab txhais ntawm 3D chaw nyob qis ib yam: Txhua yam hais txog X, Y, thiab Z-axis tseem muaj tseeb, tab sis nws muaj ib ntes. Thaum lub ntiaj teb cov khoom 3D tseem muaj nyob rau hauv peb qhov ntev, hauv lub ntiaj teb digital ntawm lub computer graphics 3D cov khoom tsuas yog tuaj yeem sawv cev los ua lej .
- 3D Qauv: Txhua tus sawv cev ntawm ib yam khoom hauv qhov chaw digital, hu ua 3D qauv . Yog hais tias koj tau saib cov ntaub ntawv raw uas muaj cov qauv yooj yim 3D , nws yuav yooj yim (los yog tsis yog li cias) yog ib phau ntawm cov ntaub ntawv cov ntsiab lus uas kos txhiab lossis tsheej lab ntawm ntau lub koom haum hauv Cartesian chaw.
- Tus software ua lej: Luckily rau cov neeg ua yeeb yam, 3D software deals nrog feem ntau ntawm cov zauv nyuaj. Tsis pub dhau cov graphical user interface ntawm 3D pob ntawv software zoo ib yam li Autodesk 3ds Max los yog Maya , 3D qauv tau txhais lus thiab pom tau tias yog cov duab cov duab hauv cov npoo, qhov muag, thiab lub ntsej muag ntau. Feem ntau cov software hauv nroog tau ua rau lub sijhawm muaj peev xwm ua rau muaj peev xwm pom cov qauv 3D uas muaj teeb pom kev zoo, ntxoov ntxoo, thiab textures.
Ntau Ntawm Z-Axis:
Txij li cov Z-axis yog xws li tus yam ntxwv tseem ceeb ntawm qhov chaw 3D, cia saib zoo li cas "Z" tiag tiag txhais tau tias nyob rau hauv ib qho chaw 3D software. Tus Z coordinate yuav siv los ntsuas plaub yam hauv 3D lub computer graphics:
- Qhov tob ntawm ib yam khoom los ntawm kev loj. Raws li nyob rau hauv, 5 units dav, 4 units siab, thiab 3 units sib sib zog nqus .
- Qhov chaw ntawm ib yam khoom nyob rau hauv relation mus rau lub hauv paus chiv keeb. Lub hauv paus chiv keeb hauv 3D scene yog (0,0,0) nrog tus thib peb naj npawb feem ntau yog "Z". Muaj ob peb lub pob me me uas siv Z ua lub voj voos, tab sis cov no muaj tsawg.
- Qhov nrug ntawm ib yam khoom los ntawm lub koob yees duab, paub hauv computer graphics li z-qhov tob. Z-Qhov feem ntau yog siv los thov qhov tob ntawm qhov kev tawm tsam tom qab tsim khoom, thiab hauv kev ua si yees duab nws tau siv rau theem kev tshaj tawm.
- Z-axis ntawm kev sib hloov . Piv txwv li, ib lub npas dawm ntawm lub koob yees duab yuav hais tau kom tig tau cov Z-axis.
3D hauv kev sib raug zoo rau Zaj duab xis / Xinesmas:
Lo lus 3D txhais tau tias ib yam dab tsi txawv nkaus thaum siv rau cov tsos cua 3D (hom uas yuav tsum tau hnav tsom iav thiab ua rau koj xav mus cuag thiab sim kov cov khoom ntawm qhov kev tshuaj ntsuam). 3D films tau, thiab feem ntau ua, muaj ib qho ntawm 3D lub computer graphics, txawm li cas los muaj ntau feeb meej tua, non-CG films uas tau noj kom zoo dua ntawm tus tshiab resurgence ntawm 3D xinesmas.
Lub ntsiab lus ntawm "3D" raws li peb xav txog nws ntawm zaj yeeb yam yeeb yam (thiab tam sim no hauv tsev ua yeeb yam ), yog tias cov neeg ua yeeb yaj kiab yuav tsum tau siv qee lub tswv yim los ua kom qhov kev pom zoo ntawm tib neeg los ua qhov kev xav tsis zoo.
- Binocular Disparity: Qhov tseem ceeb rau tib neeg kev nkag siab muaj txhua yam los ua qhov tseeb tias peb lub qhov muag txhua xa duab me ntsis rau lub hlwb. Peb lub hlwb tshem tawm txoj kev deb ntawm qhov txhais tau tias qhov txawv ntawm daim duab ntawm sab laug thiab sab xis. Qhov no yog hu ua kev tsis ncaj ncees hauv nruab nrab.
- Ib qho kev sibtham txog kev paub txog 3D lub cim kev coj ua rau lub neej muaj peevxwm tau ntev-ntev, thiab qhov no tsis yog qhov tsim nyog rau qhov ntawd. Peb yuav muab ib qho lus kawg rau koj, uas ua hauj lwm rau lub hauv paus rau li cas 3D cov yeeb yaj duab raug tsim hnub no:
- Stereoscopy: Los tsim qhov kev xav tsis zoo ntawm qhov tob, filmmakers tau tsim cov kev los ua kom muaj kev sib txig sib luag . Qhov ntau cov txhais tau tias kom ua tau qhov no yog siv cov tshuab dual lossis alternating ntsia nrog polarized tsom iav uas ua kom pom tseeb tias sab laug thiab txoj cai qhov muag ib txwm muaj duab me ntsis. Qhov no yog hu ua stereoscopy , li no lub sijhawm stereoscopic 3D .
Thiab muaj koj muaj nws!
Hopefully ntawm no taw tes koj paub me ntsis ntxiv txog 3D li nws koom computer graphics thiab zaj duab xis. Peb twb tau muab cov kev sib txuas hauv lub cev ntawm cov tshooj no, uas piav qhia txog qee cov ntsiab lus tau nthuav tawm hauv qhov tob tshaj.
