Taw qhia
Muaj ntau ntau hom qauv kev ua qauv hauv Maya, tab sis ib qho ntawm cov thawj cov txheej txheem pib feem ntau pom tau hais tias yuav ua li cas los tsim cov duab ntsuas los ntawm kev tig ib lub voj voog nyob ib ncig pivot.
Nyob rau hauv ntev ntev, nws yog ib txoj kev uas koj yuav tsis siv siv ntau npaum li cov extrude los yog ntxig yas voj cov cuab yeej, tab sis nws yog zoo meej khoom pib vim nws tso cai rau cov neeg pib tshiab pom cov txiaj ntsim tau sai heev.
Revolving ib nkhaus yog ib txoj kev yooj yim thiab yooj yim rau cov qauv khob, daim hlau, vases, txhua-txhua lub cylindrical geometry uas tawm hauv ib qho chaw. Siv curves, ib hom qauv yuav tsim tawm cov duab nyuab heev heev nyob rau lub sijhawm tsawg heev.
Hauv seem ntawm qhov kev nyeem no, peb yuav dhau mus ntawm tus txheej txheem ntawm kev ua qauv zoo nkauj champagne flute los ntawm revolving ib nkhaus.

Lub cev ntawm lub Curve
Ua ntej peb mus ua tus qauv, kuv tsuas xav nqa ob peb lub ntsiab lus tseem ceeb txog curves hauv Maya.
Kev Tswj Yeeb Yam: Cov Curves yog ua los ntawm cov ntsiab lus hu ua tswj kev tswj (CVs). Tom qab ib tus pas ntsuas, nws cov duab tuaj yeem hloov los ntawm kev xaiv tus CV thiab txav nws raws x, y, lossis z axis . Nyob rau hauv daim duab saum toj no, cov CVs ua yeeb yam li cov xim liab me me. Qhov kev tiv thaiv kab mob vertex thib peb hauv qab ntawm cov laug curve yog tam sim no xaiv rau txhais lus.
EP vs. CV Curves : Thaum koj mus rau kos ib txoj hauj lwm, koj yuav pom tias koj muaj kev xaiv ntawm cov cuab yeej EP lossis CV curve. Qhov zoo tshaj plaws kom nco ntsoov txog EP thiab CV curves yog tias qhov kawg tshwm sim yog tib yam nkaus . Qhov sib txawv ntawm qhov ob yog qhov nrog cov cuab yeej EP, tswj kev twv yoojyim ncaj qha rau ntawm qhov nkhaus xwb, thaum lub ntsiab lus tswj ntawm CV ib qho kev vam meej yeej ib txwm poob rau ntawm kab sab nraud ntawm kab. Siv qhov twg zoo li xis.
Curve Degree: Koj tuaj yeem pom kuv tau mus ua ntej thiab kos tawm ob tus curves thiab muab lawv sab ntawm sab. Ob curves yog zoo tib yam, tshwj tsis yog rau qhov tseeb hais tias ib tug yog tus thiab lwm tus yog linear. Hauv qhov kev xaiv ntawm lub thawv ntawv, npaj cov kawm ntawv rau 1 (kab) rau cov duab puab, thiab 3 (cubic) rau cov laug.
Directionality: Nws yog tsim nyog teev tias NURBS curves hauv Maya muaj ib cov kev taw qhia tshwj xeeb. Daim ntawv ceeb toom ob lub voj voog liab uas kos rau ntawm daim duab saum toj no. Lub nkhaus ntawm sab laug nws yog keeb kwm ntawm lub hauv qab, txhais tau hais tias nws flows los ntawm qab mus rau sab saum toj. Lub nkhaus ntawm sab xis yog ntxeev siab, thiab ntws saum mus rau hauv qab. Txawm hais tias txoj kab kev taw qhia tsis muaj teeb meem thaum siv qhov kev ua haujlwm loj, muaj lwm txoj haujlwm (xws li extrusion) uas coj cov kev coj mus rau hauv tus account.

Teeb duab Profile
Nws yog qhov yooj yim los tsim ib qho nkhaus hauv ib qho ntawm Maya's orthographic koob yees duab, yog li yuav hloov tawm ntawm cov seem kev vaj huam sib luag, strike spacebar . Qhov no yuav coj Maya plaub qhov kev npaj vaj huam sib luag.
Txav mus rau nas kom nws hovers nyob rau sab nraud lossis sab nraud qhov rai thiab ntaus spacebar rov mus maximize vaj huam sib luag.
Kom nkag tau rau CV Curve cuab tam, mus rau Tsim -> CV Curve Tool , thiab koj tus cursor yuav tig mus rau hauv cov khaub lig plaub hau. Tso lub taw tes tswj, nyem qhov twg hauv qhov rais. CV Curves yog ua los ntawm kev hloov, tiam sis Maya tsis tuaj yeem cuam tshuam txog thaum koj tau tso peb qho - txoj kev nkhaus yuav tshwm tawm kom txog thaum koj tau ua tiav.
Thaum tso CVs, koj tuaj yeem rub lawv mus rau ntawm daim phiaj los ntawm tuav x . Qhov no yog qhov tseem ceeb heev thaum siv qhov kev ua si qhov chaw.
Tsim ib Profile Ncej
Los tsim lub champagne flute, peb yuav siv CV lub nkhaus cuab tam kos tawm ib nrab ntawm cov duab. Snap thawj kis rau lub hauv paus chiv keeb, thiab kos cov duab ntawm qhov ntawd. Xa mus rau kuv daim ntawv ua tiav lawm hauv daim duab saum toj no, thiab nco ntsoov-koj tuaj yeem hloov qhov chaw ntawm CVs tom qab, tsis txhob hle nws yog tias koj tsis tau txais txoj cai thawj zaug.
Ua si ib ncig nrog lub cuab yeej nkhaus kom txog thaum koj twb tau txais ib daim duab zoo koj zoo siab nrog. Thaum tag nrho koj cov kev tswj kev nyob rau hauv qhov chaw, thim nkag mus tsim qhov kev nkhaus.

Revolving lub Curve
Txij ntawm no mus, txoj haujlwm ua tiav lawm.
Txhav kom tiav cov nplaum champagne, xyuas kom tseeb tias koj nyob rau hauv cov phom sij .
Nrog rau qhov nkhaus xaiv, mus rau qhov chaw -> tig thiab xaiv lub thawv xaiv los nqa qhov rais uas muaj nyob hauv daim duab saum toj no.
Hauv qhov no, qhov kev tso cai ua ntej yuav ua hauj lwm zoo kawg nkaus, tiam sis muaj ib los yog ob qho kev xaiv uas peb yuav tsum tau saib:
- Axis: Ntau zaus tsis yog koj yuav rov los ncig lub Y axis vim, tab sis x thiab y yog muaj yog tias koj xav tau lawv.
- Output Geometry - NURBS lossis Polygons: Daim ntawv ceeb toom, koj tuaj yeem tsim tau ib qho NURBS nto los yog ib qho khoom siv ntau heev . Rau tam sim no NURBS tuaj yeem xaiv, tab sis yog tias koj tus qauv yuav xaus rau hauv qhov kev ua si cav, nws yog ib lub tswv yim zoo uas siv cov duab.
- Pib & Kawg Cheb: Yog tias koj tsis xav kom koj tus cwj pwm tig rov qab puv 360 degrees, koj tuaj yeem hloov qhov kawg ntawm tus nqi sweep. Tig ib txoj hauv kev los ntawm 90 degrees tuaj yeem pab tau tsim kom muaj kev sib ze ntawm cov qauv hauv kev ua qauv.

Tiav lawm!
Muaj koj. Los ntawm kev siv ntawm Maya lub tig curve cuab tam peb tau tswj ua qauv zoo me ntsis champagne flute nyob rau hauv tsis muaj lub sij hawm tiaj.
Peb mam li tso nws nyob ntawm no tam sim no, tiam sis tej zaum nyob ze yav tom ntej peb yuav ua tus nyeem rau hauv kev tawm tswv yim zoo !
