Yuav Paub
- Qhib 2D daim ntawv qhia kev ntxhib los mos thiab xaiv Image > Txhim kho > Desaturate, tom qab ntawd hloov cov xim yog tias xav tau.
- Go to Image > Adjustments > Brightness/Contrast, teeb tusContrast rau 100 , tom qab ntawd import daim ntawv qhia mus rau hauv 3D animation program.
- Create the 3D map in Photoshop: Go to Filter > 3D > Tsim daim ntawv qhia pob. Nws yuav tsis zoo li qhov kev pab cuam 3D tuaj yeem tsim tau.
Kab lus no piav qhia yuav ua li cas ua daim ntawv qhia pob nrog Photoshop. Cov lus qhia siv rau Photoshop CC 2019 rau Windows thiab Mac.
Yuav ua li cas npaj Bump Maps hauv Photoshop
Rau cov txiaj ntsig zoo tshaj plaws, siv daim ntawv qhia nrog ntau qhov ntxoov ntxoo los simulate kev ntxhib los mos:
-
Qhib daim ntawv qhia kev ntxhib los mos 2D lossis tsim ib qho hauv Photoshop.
Koj tuaj yeem siv cov txheej txheem xws li cov qauv overlay los tsim cov ntawv rov ua dua.
Image -
Xaiv Image > Khoj > Desaturate.
Yog tias koj tau tsim koj qhov kev ntxhib los mos siv cov qauv txheej thiab cov qauv sib tshooj, koj yuav tsum tau ua kom cov txheej txheej.
Image -
Nyob hauv daim ntawv qhia pob, thaj chaw sib dua raug txhais tias ua kom zoo dua thaum qhov tsaus ntuj txhais tau tias siab dua. Yog li ntawd, nyob ntawm seb cov duab ntxoov ntxoo li cas, koj yuav tsum tau hloov cov xim kom tsim tau qhov kev xav tau. Ua li no, xaiv Image > Txhim kho > Invert
Image -
Xaiv Image> Txhim kho > Brightness/Contrast.
Image -
Set the Contrast rau 100 txhawm rau nce qhov sib txawv ntawm thaj chaw sib zog thiab tsaus nti thiab xaiv OK.
Image -
Xaiv Cov Ntaub Ntawv > Save As thiab khaws daim ntawv qhia ua hom uas sib haum nrog koj 3D qauv software.

Thaum koj tau tsim daim ntawv qhia pob, txhua yam koj yuav tsum tau ua yog import nws rau hauv koj qhov program 3D animation. Cov kev pab cuam 3D sib txawv muaj ntau txoj hauv kev ntawm kev sib koom ua ke daim ntawv qhia pob rau hauv tus qauv lossis ntau qhov chaw. Cov kev tswj hwm rau daim ntawv qhia pob yuav tsum tso cai rau koj los txheeb xyuas ntau yam kom paub tseeb tias cov khoom tsim thiab kev nyuaj siab tsis extrude mus rau qhov siab tshaj plaws lossis ntsuas me me kom lawv tsis tshua pom.
Thaum nws muaj peev xwm tsim 3D daim duab qhia ncaj qha hauv Photoshop los ntawm Filter > 3D > Tsim daim ntawv qhia pob, qhov tshwm sim yuav tsis zoo li yuav luag zoo li qhov kev pab cuam 3D tuaj yeem tsim tau.
Dab tsi yog Bump Maps?
daim ntawv qhia pob yog siv hauv 3D qauv los tsim cov khoom zoo nkauj yam tsis tas yuav ua qauv rau tus kheej cov ntsiab lus. Tag nrho 3D daim duab qhia pob pib pib ua 2D kos duab, yog li ua ntej koj qhib koj cov qauv tsim software, koj yuav tsum npaj cov duab qhia pob hauv Photoshop.
daim ntawv qhia pob yog txheej hauv qab cov xim pleev xim rau daim duab qhia kev ntxhib los mos thiab siv greyscale qhia 3D qauv kev pab cuam nyob deb npaum li cas rau extrude polygonal nto. Dub sawv cev rau qhov siab tshaj plaws ntawm extrusion, dawb sawv cev rau thaj chaw flattest, thiab ntxoov grey npog txhua yam nyob nruab nrab.
Raws dua li koj yuav tsum xaiv txhua lub pob me me ntawm koj tus qauv, daim ntawv qhia pob automates tus txheej txheem. Nws qhia 3D qhov kev pab cuam los hloov cov polygons nyob rau hauv kev sib raug zoo rau koj daim ntawv qhia pob txheej txheem, uas txo cov load ntawm lub computer cov kev pab cuam thaum nws renders tus qauv.
Piv txwv li, yog tias koj tab tom ua cov tawv nqaij lizard, daim ntawv qhia pob rau ntawm daim tawv nqaij tuaj yeem siv nruab nrab-theem grey ua lub hauv paus rau daim tawv nqaij saum npoo, nrog dawb rau qhov tob tshaj plaws thiab cov xim grey tsaus rau cov tsa. thaj chaw. Koj tuaj yeem siv daim ntawv qhia pob kom ua rau lub ntsej muag tseem ceeb thiab cov duab ntxoov ntxoo zoo li muaj tseeb lossis ntxiv cov ntsiab lus xws li quav thiab wrinkles rau tus qauv khaub ncaws.
