I-Digital dentistry ixhomekeke kwiifayile zemodeli ye-3D ukuyila kunye nokwenza ukubuyisela amazinyo njengezithsaba, iibhulorho, ukufakelwa, okanye izilungelelanisi. Iifomati ezintathu zefayile eziqhelekileyo ezisetyenziswayo yi-STL, PLY, kunye ne-OBJ. Ifomathi nganye ineenzuzo zayo kunye neengozi zayo kwizicelo zamazinyo. Kwesi sithuba sebhlog, masikhe singene kumahluko phakathi kwezona fomati zintathu zidumileyo kunyango lwamazinyo lwedijithali.

 

1. I-STL (ulwimi oluqhelekileyo lweTessellation)

I-STL yamkelwa ngokubanzi njengefomati yomgangatho weshishini loshicilelo lwe-3D kunye nezicelo zeCAD/CAM, kubandakanywa amazinyo edijithali. Imele imiphezulu ye-3D njengengqokelela yeenkalo ezinxantathu, ichaza ijometri yento.

IiPros
Ubulula: Iifayile ze-STL ziqulethe kuphela idatha yejometri yomphezulu wento ye-3D, emelwe njengomnatha ongunxantathu. Akukho mibala, ukuthungwa, okanye enye idatha eyongezelelweyo. Oku kulula kwenza iifayile ze-STL ziphathwe ngokulula kwaye ziqhubeke.

Ukuhambelana: I-STL yeyona fomati yamkelwe ngokubanzi kwisoftware yoshicilelo ye-3D kunye nehardware. Iphantse yaqinisekiswa ukuba nawuphi na umshicileli we-3D okanye isoftwe yeCAD iya kukwazi ukuphatha iifayile ze-STL.

Ububi
Ukunqongophala koLwazi lweMbala: Iifayile ze-STL azibandakanyi umbala, ukuthungwa, okanye ezinye iinkcukacha ezongezelelweyo, ukunciphisa ukusetyenziswa kwazo kwizicelo ezifuna ukubonwa kwezinto ezibonakalayo okanye iinkcukacha ezicacileyo, ezifana nemfundo yesigulane okanye ukuthengisa.
Unyino lweMetadata: Ifayile ye-STL ayikwazi ukugcina imetadata, njengombhali, i-copyright, kunye nendawo, ebalulekileyo ekupapasheni.

2. PLY (iFomathi yeFayile yePolygon)

Ifomathi ye-PLY, eyaqalwa yaphuhliswa kwiYunivesithi yaseStanford, ibonelela ngezinto ezininzi ngakumbi xa kuthelekiswa ne-STL. Ayinakugcina ijometri kuphela kodwa kunye neempawu ezongezelelweyo zedatha ezinje ngombala, ukuthungwa, kunye neempawu zezinto eziphathekayo. Oku kwenza iifayile ze-PLY zilungele usetyenziso olufuna ukumelwa okubonakalayo okongeziweyo, okufana noyilo loncumo lwedijithali okanye itrayi-ins ebonakalayo. Nangona kunjalo, kubalulekile ukuqaphela ukuba iifayile ze-PLY zithande ukuba zikhulu ngobukhulu, ezinokuchaphazela ukugcinwa kunye nokudluliselwa kwedatha.

IiPros

Ukuguquguquka:Iifayile ze-PLY azikwazi ukugcina ijometri kuphela kodwa kunye neempawu ezongezelelweyo zedatha ezifana nombala, ukuthungwa, kunye neempawu eziphathekayo, okuvumela ukubonakaliswa okubonakalayo okuphuculweyo.
Idatha eneenkcukacha:Iifayile ze-PLY zinokubamba ulwazi oluntsonkothileyo njengobushushu okanye uxinzelelo, luzenza zibe luncedo kuhlalutyo oluphambili kunye nokulinganisa.

 

Ububi

Ubungakanani beFayile enkulu:Iifayile ze-PLY zivame ukuba zikhulu ngobukhulu ngenxa yokufakwa kwedatha eyongezelelweyo, enokuchaphazela ukugcinwa kunye nokunciphisa amaxesha okucubungula.

Ukuhambelana: Iifayile ze-PLY azixhasi kangako ngabashicileli be-3D kunye nesoftware yeCAD xa kuthelekiswa ne-STL. Oku kunokufuna amanyathelo ongezelelweyo oguqulo phambi kokucubungula.

3. OBJ (iFomathi yeFayile yeNto)

I-OBJ yenye ifomathi yefayile edumileyo kwidijithali yamazinyo, eyaziwa ngokusetyenziswa kwayo ngokubanzi kwimodeli ye-3D kunye nokunikezela ngezicelo. Iifayile ze-OBJ zinokugcina zombini ijometri kunye nedatha yokuthungwa, zizenze zilungele usetyenziso apho ubukho bokwenyani bubalulekile. Ukuhambelana kwayo kunye namaqonga esoftware ahlukeneyo kunye nokukwazi ukuphatha iimodeli ezintsonkothileyo kwenza i-OBJ ibe yinto ekhethwayo yokulinganisa kwamazinyo okuphambili kunye nokucwangciswa konyango lwenyani.

IiPros
Ubume kunye nolwazi loMbala: Njenge-PLY, iifayile ze-OBJ zinokugcina ukuthungwa kunye nolwazi lombala, ukubonelela ngeemodeli ezicacileyo ezibonakalayo.
Ukuhambelana: I-OBJ ixhaswa ngokubanzi kuyo yonke isoftware yomfuziselo we-3D. Nangona kunjalo, ayizizo zonke iiprinta ze-3D ezixhasa iifayile ze-OBJ ngokuthe ngqo.

Ububi
Ubungakanani beFayile enkulu: Iifayile ze-OBJ, ngakumbi ezo zineemephu zokuthungwa, zinokuba nkulu kakhulu, ezinokucothisa amaxesha okucubungula.
Ukuntsonkotha: Iifayile ze-OBJ zinokuba nzima ngakumbi ukusebenza xa kuthelekiswa ne-STL ngenxa yeempawu ezongezelelweyo zedatha abazixhasayo.

Ukukhetha phakathi kwe-STL, i-PLY, kunye ne-OBJ kuxhomekeke kwinto oyifunayo kwimodeli yakho ye-3D. Ukuba ukulula kunye nokuhambelana okubanzi ngundoqo, i-STL inokuba lolona khetho lulungileyo. Ukuba ufuna umbala oneenkcukacha okanye enye idatha, qwalasela i-PLY okanye i-OBJ. Njengesiqhelo, kubalulekile ukuqwalasela amandla kunye nemida yesoftware yakho ethile kunye nehardware.

 

Ukukhetha ifomathi yefayile linyathelo nje elinye kwinkqubo yamazinyo edijithali. Nangona kunjalo, ukuqonda ezi fomati kunye neziphumo zazo kunokukunceda wenze izigqibo ezinolwazi kwaye ekugqibeleni unikeze ukhathalelo olungcono lwesigulana kunye neziphumo zonyango.
