Udokotela wamazinyo wedijithali uncike kumafayela emodeli ye-3D ukuze adizayine futhi enze ukubuyisela amazinyo njengemiqhele, amabhuloho, izimila, noma okuqondisayo.Amafomethi wefayela amathathu asetshenziswa kakhulu yi-STL, PLY, ne-OBJ.Ifomethi ngayinye inobuhle bayo kanye nebubi bayo bezicelo zamazinyo.Kulokhu okuthunyelwe kwebhulogi, ake sihlole umehluko phakathi kwamafomethi amathathu adume kakhulu efayela kudokotela wamazinyo wedijithali.

 

1. I-STL (Ulimi Olujwayelekile Lwe-Tessellation)

I-STL yaziwa kabanzi njengefomethi ejwayelekile yemboni yokuphrinta kwe-3D nezinhlelo zokusebenza ze-CAD/CAM, okuhlanganisa nodokotela bamazinyo wedijithali.Imele izindawo ze-3D njengeqoqo lama-facet angunxantathu, echaza i-geometry yento.

Izinzuzo
Ubulula: Amafayela e-STL aqukethe kuphela idatha yejometri engaphezulu yento ye-3D, emelelwa njengemeshi engunxantathu.Ayikho imibala, indlela yokwenza, noma enye idatha eyengeziwe.Lokhu kulula kwenza amafayela e-STL aphathe futhi acutshungulwe kalula.

Ukuhambisana: I-STL ifomethi eyamukelwa kabanzi kunayo yonke isofthiwe yokuphrinta ye-3D nehadiwe.Cishe kuqinisekisiwe ukuthi noma iyiphi iphrinta ye-3D noma isofthiwe ye-CAD izokwazi ukuphatha amafayela e-STL.

Ububi
Ukuntuleka Kolwazi Lombala: Amafayela e-STL awafaki umbala, ukuthungwa, noma enye idatha eyengeziwe, akhawulela ukusetshenziswa kwawo ezinhlelweni ezidinga okwangempela okubonakalayo noma ulwazi olunemininingwane, njengemfundo yesiguli noma ukumaketha.
Umkhawulo wemethadatha: Ifayela le-STL alikwazi ukugcina imethadatha, njengobunikazi, i-copyright, nendawo, ebalulekile ekushicilelweni.

2. I-PLY (Ifomethi Yefayela Le-Polygon)

Ifomethi ye-PLY, eyaqalwa eStanford University, inikezela ngezinto eziningi ezihlukahlukene uma iqhathaniswa ne-STL.Ayikwazi ukugcina i-geometry kuphela kodwa nezibaluli zedatha ezengeziwe ezifana nombala, ukuthungwa, kanye nezakhiwo ezibonakalayo.Lokhu kwenza amafayela e-PLY afanelekele izinhlelo zokusebenza ezidinga ukuboniswa okuthuthukisiwe okuthuthukisiwe, okufana nedizayini yokumamatheka kwedijithali noma ukuzama okubonakalayo.Kodwa-ke, kufanelekile ukuqaphela ukuthi amafayela e-PLY avame ukuba mkhulu ngosayizi, okungase kube nomthelela ekugcinweni nasekudlulisweni kwedatha.

Izinzuzo

Ukuhlukahluka:Amafayela e-PLY awakwazi ukugcina i-geometry kuphela kodwa nezibaluli zedatha ezengeziwe njengombala, ukuthungwa, kanye nezakhiwo ezibonakalayo, okuvumela ukumelwa okubonakalayo okuthuthukisiwe.
Idatha enemininingwane:Amafayela e-PLY angathwebula ulwazi oluyinkimbinkimbi njengezinga lokushisa noma ingcindezi, awenze abe usizo ekuhlaziyeni okuthuthukile nasekufaniseni.

 

Ububi

Usayizi Wefayela Omkhulu:Amafayela e-PLY avamise ukuba makhudlwana ngosayizi ngenxa yokufakwa kwedatha eyengeziwe, okungaba nomthelela ekugcinweni futhi kubambezele izikhathi zokucubungula.

Ukuhambisana: Amafayela e-PLY awavamile ukusekelwa amaphrinta e-3D nesofthiwe ye-CAD uma kuqhathaniswa ne-STL.Lokhu kungase kudinge izinyathelo ezengeziwe zokuguqulwa ngaphambi kokucubungula.

3. OBJ (Ifomethi Yefayela Lento)

I-OBJ ingenye ifomethi yefayela edumile kudokotela wamazinyo wedijithali, eyaziwa ngokusetshenziswa kwayo kabanzi ekumodeleni kwe-3D nasekunikezeni izinhlelo zokusebenza.Amafayela e-OBJ angagcina kokubili idatha yejiyomethri nokuthungwa, awenze afanelekele izinhlelo zokusebenza lapho ukubaluleka kokubukwayo kubalulekile.Ukuhambisana kwayo namapulatifomu esofthiwe ahlukahlukene kanye nekhono lokusingatha amamodeli ayinkimbinkimbi kwenza i-OBJ ibe ukukhetha okuthandwayo kokulingiswa kwamazinyo okuthuthukisiwe kanye nokuhlela ukwelashwa okubonakalayo.

Izinzuzo
Ukwakheka Nombala Ulwazi: Njenge-PLY, amafayela e-OBJ angagcina ukuthungwa nolwazi lombala, anikeze amamodeli anemininingwane ebonwayo.
Ukuhambisana: I-OBJ isekelwa kabanzi kuyo yonke isofthiwe yokumodela ye-3D.Nokho, akuwona wonke amaphrinta e-3D asekela amafayela e-OBJ ngokuqondile.

Ububi
Usayizi Wefayela Omkhulu: Amafayela e-OBJ, ikakhulukazi lawo anamamephu wokuthungwa, angaba mkhulu kakhulu, anganciphisa izikhathi zokucubungula.
Inkimbinkimbi: Amafayela e-OBJ angaba nzima kakhulu ukusebenza nawo uma kuqhathaniswa ne-STL ngenxa yezici zedatha ezengeziwe azisekelayo.

 

 (Ifayela le-OBJ likhishelwe kusukaI-Launca DL-300P)

Ukukhetha phakathi kwe-STL, i-PLY, ne-OBJ kuncike kulokho okudingayo kumodeli yakho ye-3D.Uma ubulula nokuhambisana okubanzi kungukhiye, i-STL ingaba inketho engcono kakhulu.Uma udinga umbala onemininingwane noma enye idatha, cabangela i-PLY noma i-OBJ.Njengokuvamile, kubalulekile ukucabangela amandla kanye nemikhawulo yesofthiwe yakho ethile kanye nehadiwe.

 

Ukukhethwa kwefomethi yefayela kuyisinyathelo esisodwa nje senqubo yamazinyo edijithali.Kodwa-ke, ukuqonda la mafomethi nemithelela yawo kungakusiza wenze izinqumo ezinolwazi futhi ekugcineni ulethe ukunakekelwa okungcono kwesiguli kanye nemiphumela yokwelashwa.
