Amazinyo edijithali athembele 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. Nokho, kubalulekile ukuqaphela ukuthi amafayela e-PLY avame ukuba makhudlwana ngosayizi, okungase kube nomthelela ekugcinweni nasekudlulisweni kwedatha.

Izinzuzo

Ukuhlukahluka:Amafayela e-PLY awakwazi ukugcina i-geometry kuphela kodwa nezibaluli zedatha ezengeziwe njengombala, ukuthungwa, nezakhiwo zempahla, 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. Nokho, ukuqonda la mafomethi nemithelela yawo kungakusiza wenze izinqumo ezinolwazi futhi ekugcineni ulethe ukunakekelwa okungcono kwesiguli kanye nemiphumela yokwelashwa.
