Ulandele uModeli Wokunciphisa Izindleko
Imodeli eqinile idinga izinto eziningi kakhulu ukuze ziphrintiwe kuneyodwa. Iningi labathengisi be-3D labanyathelisi bathengisa izinsizakalo zabo ngevolumu besebenzisa amentimitha angu-cubic, okusho ukuthi kunesithakazelo sakho semali ukubona ukuthi imodeli yakho imifanekiso njengesibalo esingenalutho esikhundleni sokuqina.
I-model yakho ngeke iphrinta okungekho ngokuzenzakalelayo.
Ngisho noma imodeli ibonakala sengathi iyisibopho esingenalutho ngenkathi usebenza kuhlelo lwakho lwesofthiwe ye-3D, uma imodeli iguqulwa ukunyathelisa, ihunyushwa njengokuqinile ngaphandle kokuthi uyilungiselele ngenye indlela.
Nansi indlela yokwenza imodeli yakho ingajulile:
- Khetha wonke ubuso ebusweni bomodeli.
- Ukwandisa ubuso ubuso babo obuvamile. Kungenzeka ukuthi i-extrusion enhle noma engalungile isebenza, kodwa okungalungile kuyathandwa ngoba ibhiya ukubonakala kwendawo yangaphandle ingashintshi. Uma usebenzisa ama-Maya, qiniseka ukuthi unenketho yokugcina uhlangene ndawonye . Kufanele ihlolwe ngokuzenzakalelayo.
- Hlola ubuso. Qinisekisa ukuthi akukho geometry evulekayo edalwe phakathi kwe-extrusion futhi ilungise noma yiziphi izinkinga ezingase zivele.
- I-model yakho kufanele manje ibe "negobolondo elingaphakathi" kanye "negobolondo langaphandle." Ibanga eliphakathi kwalezi zigobolondo liyoba ubukhulu besodonga lapho imodeli yakho iguqulwa. Izindonga eziqinile zihlala ziqinile kodwa futhi ziyabiza. Kungakanani isikhala osishiya kuwe. Noma kunjalo, ungahambi kakhulu. Abathengisi abaningi banesilinganiso esincane esichaza kusayithi labo.
- Dala ukuvulwa phansi kwesimodeli ukuze impahla eyengeziwe ingaphepheka. Dala ukuvulwa ngaphandle kokuphula i-topology yangempela yesikhumba-uma uvula imbobo, kubalulekile ukuguqula igebe phakathi kwegobolondo langaphakathi nangaphandle.

Khipha iJomethri Engenakuningi
Uma uqaphe ngesikhathi senqubo yokufometha, lesi sinyathelo kufanele sibe yinto engeyona inkinga.
I-geometry engekho ehlukahlukene ichazwa njenganoma yisiphi isiphetho esabelwe ubuso obungaphezu kwamabili.
Le nkinga ingenzeka uma ubuso noma ubuqili bekhipha ngaphandle kodwa abuyiselwe esikhundleni. Umphumela uba yizicucu ezimbili ze-geometry ngqo phezulu komunye nomunye. Lesi simo siphelela ukudideka ngemishini yokunyathelisa engu-3d.
Imodeli engekho eminye ngeke iphrintiwe ngokufanele.
Isizathu esisodwa esivamile se-geometry esingeyona eyejwayelekile kwenzeka uma umculi esusa ubuso, uyishukumisela, anqume ngokumelene ne-extrusion, futhi uzama ukulungisa isenzo. I-extrusion ibhalwa amaphakheji amaningi software njengemiyalo emibili ehlukene:
- I-extrusion ngokwayo
- Futhi ukuphinda kubheke ubuso noma ukuphelela
Ngakho-ke, ukulungisa i-extrusion, umyalo wokuhlehlisa kufanele unikezwe kabili. Ukwehluleka ukwenza kanjalo kuholela ekutheni i-geometry engekho ehlukile futhi kuyiphutha elivame kakhulu kwabalingisi be-novice.
Yinkinga elula ukugwema, kodwa ngokuvamile ayibonakali ngakho-ke kulula ukuyilahleka. Lungisa ngokushesha uma uqaphela inkinga. Uma usalinde isikhathi eside ukulungisa izinkinga ezingekho eziningi, kunzima ukuthi ziqede.
Ukuveza ubuso obuningi obuningi kunzima
Uma usebenzisa ama-Maya, qinisekisa ukuthi izilungiselelo zakho zokubonisa zifana nokuthi isibambo sokukhethwa-isikwele esincane noma umbuthano-sivela phakathi kwipoloni ngayinye uma usemodi yokukhetha ubuso.
Uma ubona isibambo sokukhetha ngokuqondile kunqenqemeni, cishe une-geometry engavamile. Zama ukukhetha ubuso nokuchofoza u- Susa . Ngezinye izikhathi lokhu kuyadingeka. Uma ingasebenzi, zama umyalo we- Mesh > Cleanup , uqinisekise ukuthi okungewona okhethiwe kukhethwa ebhokisini lokukhetha.
Nakuba i-extrusion akuyona imbangela yodwa yezindaba ezingezona ezehlukene, zivame kakhulu.

Hlola Izimo Ezivamile
Ubuso obujwayelekile (ngezinye izikhathi obizwa ngokuthi ubuso obujwayelekile) yi-vector eqondisayo ehambisana nomfanekiso we-3D. Yonke ubuso inobuso bayo obujwayelekile, futhi kufanele bubheke ngaphandle, ngaphandle kwendawo yomodeli.
Noma kunjalo, lokhu akusho njalo ukuthi kunjalo. Phakathi nenqubo yokufanisa , ubuso bombuso bujwayelekile bungaphambukiswa ngephutha noma kusetshenziswa amanye amathuluzi okufanisa okujwayelekile.
Uma ubuso obuvamile buguqulwa, i-vector evamile ibheke ngasekuqaleni komodeli kunokuba kude nayo.
Ukulungiswa kweziNdawo eziPhezulu
Kulula ukulungisa inkinga evamile ejwayelekile uma wazi ukuthi ikhona. Izinto ezivamile ezingabonakali ngokuzenzakalelayo, ngakho-ke cishe kuzodingeka ushintshe ezinye izilungiselelo zokubonisa ukuze ubone noma yiziphi izinkinga.
- Ku-Maya, indlela elula yokufeza lokhu ukukhuphukela ku- Buka > Ukukhanyisa uphinde ukhethe ukukhanyisa kwamabili . Uma ukukhanyisa ngamaceleni amabili kukhutshaziwe, noma yikuphi ubuso nobunzima bawo obujwayelekile obuguqulwayo bubumnyama ngokuphelele.
- Khetha lobuso, iya kumenyu ye- Polygons imenyu, bese ukhetha Izintandokazi > Phindela emuva .
- Ukuhlola izindinganiso zakho zomhlaba ngezikhathi ngezikhathi kuwumkhuba omuhle wokungena kungakhathaliseki ukuthi uhlela yini ukunyathelisa onobuhle bakho.
Imiyalo yokulungisa izinto ezijwayelekile zomhlaba zifana nazo zonke amaphakheji wesofthiwe ye-3D. Hlola amafayela wakho omsiza we-software.

Guqula ifayela lakho nokunye okucabangayo
Isinyathelo sokugcina ngaphambi kokuthi ulayishe kwenye yezinsizakalo zokuphrinta ukuqinisekisa ukuthi imodeli yakho ifomethi yefayela eyamukelekayo.
Izinhlobo ezifakiwe kakhulu zefayili yephrinta zifaka i-STL, OBJ, X3D, i-Collada, noma i-VRML97 / 2, kodwa idlale ephephile futhi uxhumane nomthengisi wakho wokuphrinta we-3D ngaphambi kokuguqula ifayela lakho.
Qaphela ukuthi amafomu okusebenza ajwayelekile afana ne-.ma, .lw, ne-.max awasekelwe. Kusukela kuma-Maya, kufanele uthekelise njenge-OBJ noma uguqulele ku-STL nge-software yangaphandle. I-3DS Max isekela kokubili i-STL ne-.OBJ yokuthumela, ngakho-ke ukhululekile ukuthatha okukhethile kwakho, nakuba ukhumbula ukuthi amafayela we-OBJ ajwayelekile kakhulu.
Umthengisi ngamunye unezinhlobo ezahlukene zefayili abamukelayo, ngakho manje yisikhathi esihle sokuhlola izinketho zakho futhi unqume ukuthi iyiphi iphrinta oyilungiselela ekusebenziseni uma ungakabi khona.
Abanikezeli Besevisi Yokuphrinta Ye-3D
Izinkampani zesevisi ezitholakala ku-intanethi ezidumile ze-3D zifaka:
- Shapeways
- Sculpteo
- Ponoko
- i.materialise
Ngaphambi kokuba unqume ukuthi yikuphi okumele uhambe naye, kungumqondo omuhle ukuphamba nge-website ngayinye yabathengisi. Thola ukuzizwa ngethenda yamakhasimende ababhekene nabo futhi babheke ukuthi ubuchwepheshe bokunyathelisa buka-3D abayisebenzisa. Lokhu kungase kube nomthelela lapho unquma khona ukuthi imodeli yakho ifakwe.
Uma usuqumile, funda ngokucophelela imiyalelo yephrinta. Into eyodwa okumele uyibuke yinkimbinkimbi yobukhulu besidonga. Qinisekisa ukucabangela iqiniso lokuthi uma uphakamisa imodeli yakho phansi, ubukhulu bodonga bayo buyoncipha. Uma izindonga zamukelekile esimweni sakho se-Maya, kodwa ubeka izilinganiso kumamitha noma ezinyaweni, kunethuba lokuthi lizoba mncane kakhulu uma ulinganisa imodeli phansi kwamasentimitha noma amasentimitha.
Kuleli phuzu, imodeli yakho ilungele ukulayisha. Njengoba ucabanga ukuthi ulandele zonke izinyathelo ezinhlanu nanoma yimiphi izithiyo ezengeziwe ezithengiswa kumthengisi, kufanele ube nomshini ohlanzekile ngendlela ehambelanayo yokunyathelisa kwe-3D.
