E fa'alagolago le foma'i nifo fa'akomepiuta i faila fa'ata'ita'iga 3D e fa'ata'ita'i ma gaosia ai fa'afouga nifo e pei o pale, alalaupapa, fa'ato'i, po'o fa'a'aoga.O faila faila masani e tolu o loʻo faʻaaogaina o le STL, PLY, ma le OBJ.E tofu le faatulagaga ma ona lava itu lelei ma le lelei mo talosaga nifo.I totonu o lenei blog post, se'i o tatou su'esu'e i le eseesega i le va o faila faila sili ona lauiloa e tolu ile fomai nifo numera.

 

1. STL (Standard Tessellation Language)

STL ua lauiloa lautele o le alamanuia tulaga masani faatulagaga mo 3D lomitusi ma talosaga CAD/CAM, e aofia ai nifo numera.O lo'o fa'atusalia luga ole 3D e pei o se aofa'iga o itu tafatolu, fa'amalamalamaina le geometry o le mea.

Fa'alelei
Faigofie: O faila STL o lo'o i ai na'o fa'amatalaga geometry luga o se mea 3D, fa'atusaina o se mata tolu.E leai ni lanu, lanu, poʻo isi faʻamatalaga faaopoopo.O lenei fa'afaigofie e faigofie ai ona fa'atautaia ma fa'agasolo faila a le STL.

Fegalegaleaiga: O le STL o le fa'asologa e sili ona talia lautele i luga ole polokalame lolomi 3D ma meafaigaluega.E toetoe lava a mautinoa e mafai e soʻo se lomitusi 3D poʻo CAD polokalama ona faʻaogaina faila STL.

Cons
Leai o Fa'amatalaga Lanu: O faila a le STL e le aofia ai lanu, lanu, poʻo isi faʻamatalaga faʻaopoopo, faʻatapulaʻaina lo latou faʻaogaina i talosaga e manaʻomia ai le vaʻaia moni poʻo faʻamatalaga auiliili, e pei o aʻoaʻoga maʻi poʻo maketi.
Metadata tapula'a: E le mafai e le faila STL ona teuina metadata, e pei o le tusitala, puletaofia, ma le nofoaga, lea e taua i le lolomiina.

2. PLY (Polygon File Format)

PLY fa'atulagaina, na fa'atupuina muamua i le Iunivesite o Stanford, e ofoina atu le tele o mea fa'atusa pe a fa'atusatusa i le STL.E mafai ona teuina e le gata o geometry ae faʻapea foʻi faʻamatalaga faʻamatalaga e pei o le lanu, lanu, ma e oʻo lava i meafaitino.O le mea lea ua talafeagai ai faila a le PLY mo talosaga e mana'omia ai le fa'aleleia atili o fa'aaliga vaaia, e pei o le ata ata fa'atekinolosi po'o le fa'ata'ita'iga fa'apitoa.Ae ui i lea, e taua le matauina o faila PLY e foliga mai e lapopoa i le lapopoa, e ono aʻafia ai le teuina ma le fesiitaiga o faʻamatalaga.

Fa'alelei

Fetuuna'i:O faila PLY e mafai ona teuina e le gata o geometry ae faʻapea foʻi faʻamatalaga faʻamatalaga e pei o le lanu, lanu, ma meafaitino, faʻatagaina mo le faʻaleleia atili o foliga vaaia.
Fa'amatalaga Auiliili:E mafai e faila a le PLY ona pu'eina fa'amatalaga lavelave e pei o le vevela po'o le mamafa, e fa'aoga ai mo au'ili'iliga ma fa'ata'ita'iga.

 

Cons

Tele File Tele:O faila PLY e foliga mai e lapopoa i le lapopoa ona o le aofia ai o faʻamatalaga faaopoopo, lea e mafai ona aʻafia ai le teuina ma faʻagesegese taimi faʻagaioiga.

Fegalegaleaiga: O faila PLY e le masani ona lagolagoina e lomitusi 3D ma CAD polokalama faʻatusatusa i le STL.Atonu e mana'omia ni laasaga faaopoopo o le liua a'o le'i faia.

3. OBJ (Faiga Fa'atonu Fa'atonu)

OBJ o le isi faila faila lauiloa i nifo numera, lauiloa mo lona faʻaogaina lautele i faʻataʻitaʻiga 3D ma tuʻuina atu talosaga.O faila o le OBJ e mafai ona teuina uma faʻamaumauga o geometry ma faʻamatalaga, faʻapena ona talafeagai mo faʻaoga e taua tele ai le vaʻaia.O lona fetaui lelei ma polokalame eseese ma le mafai ona taulimaina faʻataʻitaʻiga lavelave ua avea ai le OBJ ma filifiliga sili mo faʻataʻitaʻiga faʻataʻitaʻi nifo ma fuafuaga faʻataʻitaʻiga.

Fa'alelei
I'uga ma Fa'amatalaga Lanu: E pei o le PLY, o faila o le OBJ e mafai ona teu ai fa'amatalaga ma fa'amatalaga lanu, e maua ai fa'ata'ita'iga sili atu ona va'aia.
Fegalegaleaiga: OBJ o lo'o lagolagoina lautele i polokalame fa'atusa 3D.Ae ui i lea, e le o lomitusi 3D uma e lagolagoina sa'o faila OBJ.

Cons
Tele File Tele: O faila o le OBJ, aemaise lava i latou o loʻo iai faʻafanua faʻafanua, e mafai ona lapopoa, e mafai ona faʻagesegese taimi faʻagaioia.
Lavelave: O faila OBJ e mafai ona sili atu ona lavelave e galulue faʻatusatusa i le STL ona o faʻamatalaga faʻaopoopo faʻamatalaga latou te lagolagoina.

Filifilia ile va ole STL, PLY, ma le OBJ e fa'alagolago ile mea e te mana'omia mai lau fa'ata'ita'iga 3D.Afai o le faigofie ma le lautele o fesoʻotaʻiga e taua, e mafai ona avea le STL ma filifiliga sili.Afai e te manaʻomia le lanu auiliili poʻo isi faʻamatalaga, mafaufau i le PLY poʻo le OBJ.E pei lava o taimi uma, e taua le mafaufau i gafatia ma tapulaʻa o lau polokalama faʻapitoa ma meafaigaluega.

 

O le filifiliga o le faila faila e na o le tasi le laasaga i le faagasologa o nifo numera.Ae ui i lea, o le malamalama i nei faʻatulagaga ma o latou aʻafiaga e mafai ona fesoasoani ia te oe e faia ai faʻaiuga sili atu ona malamalama ma iʻu ai ina sili atu le tausiga o maʻi ma togafitiga.
