Uhlolojikelele
I-DMTet (Deep Marching Tetrahedra) iwumfanekiso oyingxube we-3D oyingxubevange ohlanganisa igridi ye-tetrahedral egogekayo nenkambu yebanga esayiniwe ukuze amanethiwekhi emizwa akwazi ukukhiqiza imininingwane enemininingwane, engangeni manzi ngokuqondile. Ibalulekile ngoba yenza isizukulwane se-3D mesh enesinqumo esiphezulu sihlukaniseke futhi siqeqesheke ekugcineni.
I-DMTet Hybrid 3D Representation ingeyokugeleza kokusebenza kombono wekhompyutha okuhumusha noma okukhiqiza imidiya ebonakalayo ukuze ihlaziywe, isebenze, futhi isungule.
I-Deep Dive
I-DMTet, eyethulwe i-NVIDIA ngo-2021, ihlanganisa izethulo ezicacile nezicacile ze-3D. Iqala ngegridi ekhubazekile ye-tetrahedra; ku-vertex yegridi ngayinye inethiwekhi ibikezela inani elisayiniwe lebanga (elihle ngaphandle kwendawo, elinegethivu ngaphakathi) kanye ne-position offset. Isendlalelo se-Maring Tetrahedra esihlukanisayo sibe sesikhipha inetha elingunxantathu osobala nomaphi lapho uphawu lwenkambu yebanga luphenduphenduka lunqamula unqenqema lwe-tetrahedron. Ngenxa yokuthi womabili amanani e-SDF kanye nokuma kwe-vertex kuyafundwa futhi ukukhipha okungaphezulu kuyahlukaniseka, ungakwazi ukuthuthukisa wonke amapayipi ngokumelene nokulahlekelwa kwesithombe se-2D noma ukugadwa kwe-3D. I-DMTet iphinde isekele ukuhlukaniswa iziqephu okumaholoholo kuya kokuhle, icwenga i-tetrahedra kuphela eduze nendawo ukuze yengeze imininingwane yejometri kahle ngaphandle kokumosha umthamo endaweni engenalutho.
I-Technical Insight
Iqhinga ungqimba lweTetrahedra olumashayo oluhlukanisekayo: i-tetrahedra yakudala ayihlukanisi ngenxa yokuthi i-mesh topology ishintsha ngokusobala, kodwa i-DMTet igcina ama-gradient egeleza ngamavelu e-SDF abikezelwe kanye nokuguqulwa kwe-vertex okunquma ukuthi ama-vertices angaphezulu ahlala kuphi. Amathrendi angaphezulu abekwe ngokuhumusha ngomugqa emaphethelweni e-tetra kusetshenziswa ukuguqulwa kophawu lwe-SDF, ngakho indawo nemininingwane kuthuthukiswa ngokuqhubekayo kuyilapho i-topology ijwayela.

Ukuze wakhe ukuqonda okujulile, phatha i-DMTet Hybrid 3D Representation njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela oyifunayo, ucacise ukucabanga, futhi uhlukanise lokho uhlelo olungakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa ukunemba kwebhalansi ye-DMTet Hybrid 3D Representation namaqiniso okusebenza njengekhwalithi yedatha, ukuhluka kokukhanya, nokuvumelana kwamalebula. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
I-Visual AI ingakwazi ukuhlola, ukutholwa, nokumaka imisebenzi esikalini. Ngesikhathi esifanayo, amalungelo ezithombe kanye nemvume kungaba ubungozi bomthetho uma ukutholakala kungacacile. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
