Daim Duab 3D nrog AutoCAD - Tshooj 8

TSHOOJ 40: QAUV

Peb hu ua Modeling cov txheej txheem ntawm kev tsim cov duab tiag tiag los ntawm 3D qauv, txawm hais tias nws tau paub ntau dua los ntawm anglicism "rendering". Cov txheej txheem no muaj peb theem: a) Muab cov khoom sib txawv, qhov chaw thiab cov meshes ntawm cov qauv rau kev sawv cev ntawm cov khoom (ntoo, hlau, yas, pob zeb, iav, thiab lwm yam); b) Tsim ib qho chaw dav dav uas pom tus qauv: teeb, keeb kwm yav dhau, pos huab, duab ntxoov ntxoo, thiab lwm yam; c) Xaiv hom rendering, qhov zoo ntawm cov duab thiab cov khoom tsim tawm.
Nws yooj yim hais, tab sis qhov no yog thaj chaw ntawm CAD uas, txawm hais tias tsis yog qhov nyuaj los nkag siab, yuav tsum muaj ntau txoj hauv kev kom ua tiav cov txiaj ntsig tau zoo nrog ob peb sim. Ntawd yog, nws yog qhov yuav tsum tau hais tias ntau lub sijhawm ntawm kev sim thiab yuam kev yuav tsum tau siv los kawm cov qauv zoo tshaj plaws rau cov kev faib cov khoom kom raug, kev siv cov ib puag ncig thiab cov teeb ci thiab cov cim tsim txiaj ntsig.
Txhua ntu, nyeg, cuam tshuam nrog kev tsim ntawm ntau tus qauv, uas nws hloov, txawm hais tias me me, ib txwm cuam tshuam rau qhov kawg ua tiav. Piv txwv li, peb tuaj yeem txiav txim siab tias lub duab plaub lub duab plaub yog ua los ntawm cov iav, uas yuav yuam nws kom muaj qee qhov kev xav thiab pom tseeb, yog li nws yuav tau hloov kho cov kev ntsuas ntawd kom ua tiav cov txiaj ntsig zoo. Nyob rau hauv lem, phab ntsa, yuav pom qhov zoo li ntawd, yuav tsum muaj qhov kev ntxhib ntawm cov MAAs. Tib yam tuaj yeem hais tau ntawm cov hlau qhov ntawm lub tsheb lossis cov yas ntawm cov khoom siv. Tsis tas li ntawd, nws ib txwm tsim nyog los siv cov teeb ci kom raug, xav txog lub teeb ntsig txog lub teeb, qhov deb thiab qhov deb ntawm lub chaw taws teeb. Yog tias nws yog lub teeb tsom, nws yuav tsum tau ua kom qhov tseeb txhawm rau kom cov duab ntxoo zoo. Xws li cov phiaj xwm kos duab, qhov chaw muaj tseeb ntawm hnub ci, xav txog hnub tim thiab sijhawm, yog qhov tseem ceeb kom paub cov tsos ntawm cov khoom ntiag tug uas tseem tsis tau tsim.
Yog li, kev ua qauv lossis kev ua haujlwm tuaj yeem yog qhov nyuaj tab sis yeej tau txais txiaj ntsig ib txoj haujlwm. Ntau lub tuam txhab ua haujlwm hauv lub tsev ua haujlwm tau muab lub siab zoo ntawm lawv lub zog los ua qauv ntawm lawv cov phiaj xwm ua ntej nthuav tawm rau lawv cov neeg siv khoom thiab muaj cov chaw ua haujlwm tshwj xeeb los tsim cov qauv sab nraud rau tus kheej, hloov cov txheej txheem no mus rau thaj chaw ua lag luam hauv nws tus kheej, yog tias tsis yog, Txawm nyob hauv ib daim duab.

Cia peb saib ntawm Autocad Modeling cov txheej txheem.

40.1 Cov Ntaub Ntawv

40.1.1 Kev cob qhia ntawm cov ntaub ntawv

Ib qho ntawm thawj kauj ruam peb yuav tsum ua los tsim cov txiaj ntsig zoo photorealistic ntawm tus qauv 3D yog kom muab cov ntaub ntawv los sawv cev hauv txhua qhov khoom. Yog tias peb kos tsev, tej zaum muaj qee ntu yuav tsum sawv cev ua vaj tse, lwm cov cib thiab qee cov ntoo ntxiv. Hauv qee cov qauv paub daws teeb, koj yuav xav sawv cev rau lwm cov ntaub ntawv lossis cov qauv rau cov uas nws yuav tsum tau hloov kho qhov tsis txawv ntawm cov khoom siv uas twb muaj lawm. Los ntawm lub neej ntawd, Autocad suav nrog ib ncig ntawm 700 cov ntaub ntawv thiab 1000 textures npaj los muab rau tus qauv qauv khoom.
Nws yuav tsum nco ntsoov tias Autocad nraaj qhov rai yuav qhia lossis tsis yog qhov kev sim yooj yim ntawm cov ntaub ntawv nyob ntawm qhov pom siv tau siv. Pom tseeb, cov qauv pom zoo rau cov rooj plaub no yog hu ua Kev Tseeb, Txawm hais tias qhov ntawd tsis tau txhais tias qhov pom ntawm lub qhov rai nraaj twb tau ua qauv.
Thaum tus tsim qauv pom tau tseeb, kev nkag mus, siv thiab tsim kho ntawm cov ntaub ntawv no zoo ib yam nyob hauv txhua kis dhau ntawm, ua ntej, Cov Ntawv Tshawb Xyuas Cov Khoom Siv, uas muaj nyob hauv Cov Khoom seem ntawm Render tab.
Cov Ntawv Tshawb Fawb Cov Khoom Siv tso cai rau peb kom paub cov ntaub ntawv ntau yam thiab pawg uas lawv tau teeb tsa. Hauv nws koj yuav pom Autodesk lub tsev qiv ntawv cov ntaub ntawv, cov ntaub ntawv zoo li tsis tuaj yeem hloov kho, rau qhov no nws yog qhov tsim nyog, lossis muab lawv rau hauv cov duab kos tam sim no, lossis tsim cov tsev qiv ntawv customized ntawm cov ntaub ntawv uas koj tuaj yeem hu tom qab los ntawm lwm cov duab kos rau kev siv. Yog tias koj tsis npaj siab yuav hloov kho cov ntaub ntawv, tom qab ntawd koj tuaj yeem muab lawv rau koj tus qauv ncaj qha los ntawm lub tsev qiv ntawv Autodesk thiab hla kev tsim koj lub tsev qiv ntawv.

Qhov tseeb, ua ntej muab cov khoom rau 3D yam khoom, nws yog qhov tseem ceeb ua ntej ua kom cov khoom siv thiab cov qauv hauv cov qauv. Qhov no yooj yim npaum li nias lub pob ntawm tib lub npe hauv Cov Khoom. Qhov thib ob uas yuav tsum xav txog yog tias qhov raug siv ntawm cov textures ntawm ib qho khoom yog nyob ntawm nws cov duab. Nws tsis yog tib yam los muab cov khoom rau ib voos dua rau ib lub voos xwmfab. Yog tias ib qho khoom txwv yog qhov nkhaus, tom qab ntawd qhov zoo li ntawm nws cov ntawv yuav tsum ua raws, thiab qhia, xws li curvature. Rau qhov kev sim ntawm cov khoom siv ntawm 3D cov khoom kom ua haujlwm tau zoo, daim ntawv qhia kev faib tawm ntawm daim duab nyob sab nraud ntawm tus qauv yuav tsum tsim nyog. Qhov kev zov me nyuam xav tau kev ntxhib los mos daim ntawv qhia parameter kom siv rau txhua yam khoom siv thiab rau lub hom phiaj ntawd khawm tom ntej hauv ntu ntawd tau siv.

Nyob rau hauv txhua rooj plaub, raws li koj tau txheeb xyuas qhov tseeb, txoj haujlwm ntawm cov khoom siv rau cov khoom siv yog qhov yooj yim heev, tsuas yog xaiv cov khoom siv, los ntawm lub tsev qiv ntawv Autodesk, los ntawm cov uas tau koom rau hauv cov duab kos lossis los ntawm koj tus kheej lub tsev qiv ntawv thiab tom qab ntawd taw tes rau qhov khoom xav tau. Nws tseem tuaj yeem xaiv ib qho khoom thiab tom qab ntawd nias ntawm qhov khoom.
Lwm qhov kev xaiv tuaj yeem yog xa cov khoom siv rau tsuas yog ib lub ntsej muag ntawm cov khoom. Txhawm rau ua qhov no peb tuaj yeem siv cov ntawv lim dej subobject lossis nias CTRL kom xaiv lub ntsej muag, tom qab ntawd peb nyem rau ntawm cov khoom.

Ib qhov kev teeb tsa dua rau kev muab cov khoom yog los ntawm kev siv cov khaubncaws sab nraud povtseg, txawm hais tias nrog tus qauv no peb tsuas tuaj yeem muab cov ntaub ntawv uas tau muab tso rau yav dhau los kos duab tam sim no, raws li peb pom hauv daim video dhau los. Rau qhov no peb siv khawm txuas Cov khoom siv los ntawm txheej ntawm ntu ntu peb tab tom kawm, uas qhib ib lub chaw sib tham uas peb tsuas tau txuas cov khaubncaws sab nraud povtseg sib txawv rau cov khoom siv tau xaiv. Yog li ntawd, cov qauv txheej txheem qauv zoo yuav yooj yim rau kev faib cov khoom siv.
