Squash thiab Stretch nyob rau hauv Animation: Qhov zais cia rau qhov tseeb txav
Squash thiab stretch yog cov kab lus siv los piav txog "qhov tseem ceeb tshaj plaws" ntawm 12 lub hauv paus ntsiab lus ntawm animation, tau piav nyob rau hauv phau ntawv Illusion of Life los ntawm Frank Thomas thiab Ollie Johnston.
Squash thiab ncab yog cov txheej txheem siv los ua cov khoom thiab cov cim kom pom tseeb dua thaum cov animated. Nws suav nrog deforming cov khoom kom nws zoo li nws muaj cov khoom siv lub cev. Cov txheej txheem no yog siv los tsim qhov illusion ntawm zog thiab hnyav hauv animation.
Los ntawm exaggerating lub squash thiab stretch, animators muaj peev xwm ntxiv ntau tus cwj pwm thiab qhia rau lawv cov cim. Zuag qhia tag nrho, squash thiab ncab yog cov cuab yeej tseem ceeb hauv cov khoom siv animator los tsim cov animation uas ntseeg tau thiab koom nrog.
Hauv kab ntawv no peb yuav npog:
Xauv Khawv koob ntawm Squash thiab Stretch
Raws li ib tug animator, kuv yeej ib txwm tau fascinated los ntawm lub hwj chim ntawm squash thiab stretch ua pa lub neej rau cov cim thiab cov khoom. Qhov no txoj cai ntawm animation tso cai rau peb los tsim cov dynamic txav uas xav tias zoo dua thiab ntseeg tau. Nws yog txhua yam hais txog qhov hloov maj mam hloov hauv cov duab uas tshwm sim raws li cov khoom lossis tus cwj pwm cuam tshuam nrog nws ib puag ncig.
Piv txwv li, xav txog kev kos ib lub pob roj hmab bouncing. Thaum nws tsoo hauv av, nws squashes, thiab thaum nws tawm mus, nws ncab. Qhov kev hloov pauv hauv cov duab no ncaj qha qhia txog kev quab yuam siv rau cov khoom siv thiab muab cov animation rau kev nkag siab ntawm elasticity thiab yooj.
Siv Txoj Cai nrog Finesse
Thaum thov squash thiab ncab, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj kom tsis txhob overboard. Qhov kev sib tw loj tshaj plaws yog tawm tsam qhov sib npaug zoo tshaj plaws ntawm kev tshaj tawm thiab tswj cov khoom ntim. Nov yog qee cov lus qhia kuv tau khaws los ntawm txoj kev:
- Ntsuam xyuas cov qib sib txawv ntawm squash thiab ncab kom pom tias zoo li cas rau cov khoom lossis tus cwj pwm uas koj tab tom ua kom muaj zog. Lub pob roj hmab yuav xav tau ntau qhov kev hloov pauv hauv cov duab ntau dua li lub pob balling hnyav.
- Khaws cov khoom ntim kom zoo ib yam. Thaum nws squashes, ob sab yuav tsum ncab tawm, thiab thaum nws stretches, ob sab yuav tsum nqaim.
- Ua tib zoo saib lub sijhawm ntawm squash thiab ncab. Cov nyhuv yuav tsum tau siv smoothly thiab nyob rau lub sijhawm zoo los tsim kom muaj kev nkag siab zoo ntawm cov lus tsa suab.

- Kev sim nrog cov ntaub ntawv sib txawv thiab cov khoom siv los kawm seb lub hauv paus ntsiab lus tuaj yeem hloov kho kom haum rau ntau theem ntawm kev hloov pauv thiab elasticity.
- Kawm txog kev ua haujlwm ntawm lwm cov animators thiab ua tib zoo saib xyuas seb lawv siv squash thiab ncab li cas los tsim kom muaj kev koom tes ntau dua thiab muaj sia nyob.
Mastering Art of Squash thiab Stretch hauv Animation
Tau ntau xyoo, kuv tau pom tias squash thiab ncab tuaj yeem siv tau rau yuav luag txhua yam kev ua yeeb yam, txawm tias nws yog tus cwj pwm lossis khoom siv. Nov yog qee qhov piv txwv ntawm qhov kuv tau siv squash thiab ncab hauv kuv txoj haujlwm:
Cim dhia:
Thaum tus cwj pwm dhia mus rau saum huab cua, Kuv yuav siv squash los qhia qhov kev cia siab thiab tsim lub zog ua ntej dhia, thiab ncab kom hais txog qhov nrawm thiab qhov siab ntawm dhia.
