Intshayelelo
Kukho izixhobo ezininzi zohlobo lweMaya, kodwa enye yeziqalo zokuqala eziqalayo zibonakaliswa ngendlela yokudala i-geometry ngokuguqula ijika elijikeleze i-pivot.
Ekuhambeni kwexesha, yinkqubo mhlawumbi awuyi kuphelisa ukusebenzisa i- extrude okanye ufake i-loop tool tools, kodwa yinto ecacileyo yokuqala ngoba ivumela abaqalayo ukuba babone iziphumo ezibonakalayo ngokukhawuleza.
Ukuguqula ikhefu yindlela ekhawulezayo kwaye elula yokubonisa iikomityi, iiplate, iifestile, iikholomu-nayiphi na i-geometry ejikelezayo ephuma kwindawo ephakathi. Ukusebenzisa ii-curve, umenzi-modeli angavelisa imilo eqhelekileyo ye-radial ngexesha elincinci.
Konke oku kufundiswa, siya kuhamba kwinkqubo yokumisela umlingo we-champagne olula ngokuguqula ijika.

Inatomy of Curve
Ngaphambi kokuba sifumane imodeli, ndifuna nje ukuvelisa amaphuzu ambalwa ngokukhawuleza malunga neengcingo zaseMaya.
Ukulawula iiValti: Iingqungquthela zenziwe ngamanqaku abizwa ngokuba ngama-vertic control (CVs). Emva kokuba ikhefu ithatywe, umlo wayo unokuguqulwa ngokukhetha i-CV kwaye uyishukumisela ukuyifaka kunye ne-x, y, okanye i- axis . Kumfanekiso ongentla, ii-CV zibonakalisa njengezikwere ezincinci. I-vertex yesithathu yolawulo ukusuka ngasezantsi kwekhava langasese ngoku okhethwe ngokuguqulelwa.
I-EP ne-CV Curves : Xa uhamba ukudweba i-curve, uya kubona ukuba unokhetho phakathi kwe-EP okanye i-CV i-curve. Into ephambili yokugcina ingqalelo ngee-EP kunye ne-CV curve kukuba umphumo wokugqibela ufana ngokufanayo . Umehluko kuphela phakathi kwezi zibini kukuba nge-EP ithuluzi, ulawulo lwama-vertic lilala ngqo ngqo kwi-curve ngokwayo, ngelixa ulawulo olukhomba kwi-curve ye-CV luhlale luwela kwicala lokuxhoma lomgca. Sebenzisa nantoni na oziva ekhululekile.
I-Curve Degree: Uyabona ndiqhube phambili kwaye ndikhupha iirebhu ezimbini kwaye ndawabeka ecaleni. Iimitha ezimbini zifana ngokufanayo, ngaphandle kokuba enye ihamba kakuhle kwaye enye ingqinelana. Kwibhokisi lokukhetha i-curves, misela i-degree (1) (umgca) kwiimpawu zengqumbo, kunye ne-3 (cubic).
Ulawulo: Kubalulekile ukuba uqaphele ukuba i- NURBS curve kwi-Maya inokhetho oluthile. Qaphela izibini ezibomvu ezibekwe kumfanekiso ongentla. Ikhefu ngakwesobunxele inemvelaphi ephantsi, ithetha ukuba iphuma ukusuka phezulu ukuya phezulu. Ikhefu ngakwesokudla iguqulwa, kwaye ijikeleza phezulu ukuya phezulu. Nangona ulwalathiso lwengqungquthela aluncedo xa usebenzisa umsebenzi wokuguquka, kukho enye imisebenzi (njenge-extrusion) ethatha i-account management account.

Udweba i Curve Profile
Kulula ukudala i-curve kwelinye leekhamera ze-Maya, ukuze uguqulwe kwiplanethi yembono, ibha yomgca wecala . Oku kuza kubangela ukuma kwepaneli yamaMaya amane.
Hambisa imouse ukuze ijikeleze kwinqanaba langasese okanye phambi kwewindow kwaye uphinde uqhube umgca we-spacebar ukuze ukwandise iphaneli.
Ukufikelela kwisixhobo seCV Curve, iya ku Yakha i- CV Curve Tool , kwaye isikhokhelo sakho siza kuba ziinwele. Ukubeka indawo yokulawula, nqakraza naphi na kwifestile. Iingqungquthela ze-CV zihamba ngokugqithiseleyo, kodwa iMaya ayikwazi ukudibanisa ukukhanya kuze kube yilapho ubeke iintsimbi ezintathu-i-curve iya kubonakala iqhelekileyo uze wenze njalo.
Xa ufaka ii-CVs, ungazifakela kwi-grid ngokubamba x . Oku kuyanceda kakhulu xa kulungiswa imimandla yemidlalo.
Ukudala i Curve Profile
Ukudala umlingo we-champagne, siza kusebenzisa ithuluzi le-curve yeCV ukuze siphume isiqingatha somlo. Songa iqhosha lokuqala kwimvelaphi, kwaye uqhubeke udweba iphrofayili apho. Khangela kwinqanaba lam eligqibekileyo kumfanekiso ongentla, kwaye khumbula-unokuguqula isikhundla se-CVs kamva, ngoko musa ukusifungela xa ungawafumani ngokufanelekileyo okokuqala.
Dlala ujikeleze ngethuluzi lokujika uze ufumane ukuma kwefayile ovuyayo. Xa zonke izitrandi zakho zokulawula zikhoyo, gxininisa ukungena ukuze wakhe ikota.

Ukuguqula iKharve
Ngeli nqanaba, umsebenzi onzima uphelile.
Ukugqiba umlingo we-champagne, qiniseka ukuba usemodyuli yomhlaba .
Ngekhethi ekhethiweyo, iya kwiindawo -> vula uze ukhethe ibhokisi lokukhetha ukukhupha ifestile eboniswe kumfanekiso ongentla.
Kule meko, izicwangciso zangasese ziya kusebenza kakuhle, kodwa kukho enye okanye ezimbini iindlela esinokuzijonga ngayo:
- I-Axis: Ngokuphindaphindiweyo kunokuba uya kuba ujikeleze nge-Y axis, kodwa x ne-y ziyafumaneka xa ufuna.
- I-Geometry ye-Output - I-NURBS okanye i-Polygons: Isaziso, unakho ukuvelisa umgangatho we-NURBS okanye into ye- polygon . Ngoku ngoku ii-NURBS zihlala zikhethiweyo, kodwa ukuba imodeli yakho ekugqibeleni igqiba kwi-injini yegeyimu, yinto efanelekileyo yokusebenzisa iipoloni.
- Qala & Vala Ukuphela: Ukuba awufuni ukuba ikheve yakho iguqule ii-360 degrees ezipheleleyo, ungatshintsha ixabiso lokuphela. Ukujikeleza ijika nge 90 degrees kunokuba luncedo ekudaleni ingqungquthela yokujikeleza.

Igqitywe tu!
Naku ulapha. Ngokusebenzisa ithuluzi lokujika lomzila weMaya siye sakwazi ukumisela umtsalane omncinci we-champagne ngaphandle kwiphathi.
Siza kushiya apha ngoku, kodwa mhlawumbi kusasa siza kwenza uqeqesho ekunikezeni i- caustics!
