Thaum koj kawm ua 2D sawv cev ntawm 3D khoom ntawm qhov screen, xav txog 3D topology li wireframe ntawm ib yam khoom. Lub wireframe, uas raug xa mus rau hauv 3D software raws li lub mesh, yog tsim los ntawm ntau pua lossis txhiab tus duab geometric yooj yim.
Lub sij hawm topology yog hais txog geometric nto yam ntxwv ntawm lub mesh. Txhua geometric nto ntawm lub mesh yog lub ntsej muag. Lub wireframe yog lub hauv paus ntawm 3D qauv, uas thaum kawg ua rau peb-dimensional digital animation.
Wireframe yam ntxwv ntawm Zoo Topology
Ib lub wireframe muaj ntau ntau polygons, vertices (tus taw tes ntawm peb los yog ntau dua npoo sib ntsib), npoo (kab ua los ntawm ob vertices), arcs, curves, thiab voj voog. Cov duab no tsim lub ntsej muag nyob rau hauv lub wireframe tsim.
Hauv computer-tsim 3D topology, lub hom phiaj yog kom muaj cov ncauj lus kom ntxaws txaus hauv lub wireframe thaum khaws cov ntsej muag mus rau qhov tsawg kawg nkaus uas tsim nyog los ua kom tiav txoj haujlwm. Nyob rau hauv cov cheeb tsam uas tus qauv 3D yuav tsum khoov lossis txav mus, tus tsim qauv feem ntau nce tus lej ntawm cov polygons kom tso cai rau kev txav mus los yam tsis muaj kev cuam tshuam.
Lwm qhov, tsawg dua polygon yuav tsum tau. Lub tswv yim no yog qhov tseem ceeb thaum ua qauv rau 3D animation. Lub ntsej muag ntau ntxiv nyob rau hauv thaj chaw ntawm tus qauv 3D uas ua rau muaj kev hloov pauv ntau tshaj plaws thaum lub sijhawm ua yeeb yaj kiab, xws li cov pob qij txha, lub ntsej muag lub ntsej muag, thiab cov khoom txav, yog qhov tseem ceeb rau cov lus tsa suab tiag tiag.
3D cov qauv siv zog ua kom huv si topology, feem ntau yog qhia los ntawm 3D mesh nrog kev faib cov polygon kom zoo, muab tso rau ntawm ntug loops, thiab huv si, meej creases uas txo stretching thiab distortion.
Cov lus qhia pib ntawm Topology thiab 3D Qauv
Topology yog lub ntsiab lus loj, tab sis pib 3D qauv tuaj yeem tau txais txiaj ntsig los ntawm ob peb lub tswv yim:
- Siv plaub-sided polygons dawb, tab sis zam N-gons uas muaj tsib lossis ntau sab.
- Siv daim duab peb sab sparingly tshwj tsis yog lub software koj siv txais tos daim duab peb sab meshes (qee ua).
- Tsis txhob siv cov polygons elongated. Plaub-sided polygons yuav tsum yog square.
- Cia nws yooj yim thaum pib. Ua qauv ib square los yog ib tug kheej kheej. Tom qab ntawd, txav mus rau kev ua qauv snowman, uas feem ntau yog spheres, square, thiab daim duab peb sab. Tsis txhob pib nrog qhov kev xav tau kom txog thaum koj txaus siab nrog software.
- Thaum koj npaj txhij, sim qee qhov yooj yim online 3D qauv qhia kev qhia.
- Txawm tias koj tuaj yeem them taus qhov saum toj-ntawm-tus-kab 3D qauv software, pib nrog ib qho ntawm cov kev pab cuam 3D pub dawb rau cov pib tshiab.
- 3D qauv yog qhov nyuaj rau kawm. Ua siab ntev.
3D Modeling Software rau Beginners
Ntau qhov kev pab cuam 3D pub dawb muaj. Ib qho ntawm cov no yog qhov chaw muaj txiaj ntsig rau tus qauv pib pib:
- Daz Studio
- Hexagon
- Blender
- Sculptris
Feem ntau 3D qauv software qhov chaw muab cov yeeb yaj duab qhia los pab cov neeg pib paub txog cov ntsiab lus qab 3D qauv.
3D Modeling Software rau cov kws tshaj lij
Kev tshaj lij-qib 3D qauv kev pabcuam tuaj yeem ua rau ntshai thiab kim. Txawm li cas los xij, xav tias koj npaj yuav ua haujlwm hauv 3D animation (txawm yog tsim cov yeeb yaj kiab ua si, khoos phis tawj duab, lossis yeeb yaj kiab). Nyob rau hauv tas li ntawd, koj yuav tsum tau los ua ib tug kws nyob rau hauv ib tug ntawm lawv. Advanced-level 3D modeling software programs suav nrog:
- Autodesk Maya
- Modo by Foundry
- Adobe Fuse CC
- NewTek LightWave 3D
- Poser los ntawm SmithMicro
- Maxon Cinema 4D
- Autodesk 3ds Max Tsim
