Ewebatara na SIGGRAPH 2023, 3D Gaussian Splatting na-ewughachi ihe onyonyo sitere na foto dị ka NeRF mana ọ na-eji ngosipụta doro anya kama netwọọkụ akwara zoro ezo. Ihe nkiri ọ bụla bụ igwe ojii nke Gaussians 3D, blobs ellipsoidal na-enweghị isi, na blob nke ọ bụla na-echekwa ọnọdụ, nha na nghazi (nkwekọrịta ya), opacity, na agba. Kama iji nwayọọ na-agbapụ ụzarị ọkụ site na netwọk, usoro a "splats" ndị a blobs ozugbo na ihuenyo wee jikọta ha, usoro dị nso na rasterization omenala na ya mere ngwa ngwa. Ọzụzụ na-amalite site na igwe ojii na-adịghị ahụkebe nke nhazi igwefoto na-emepụta, wee na-ebuli blobs ahụ ka ọ na-agbakwụnye nkọwa zuru ezu ebe ebe a na-arụzigharị ihe ahụ na ịkwachaa ebe ndị mmadụ juru.

Kedu ihe bụ Gaussian Splatting?
Gaussian Splatting na-anọchi anya ihe nkiri 3D dị ka nde obere obere, agba, nke nwere ike ịsụgharị ya ozugbo. Ọ na-enye NeRF dị ka fotorealism ka ọ na-agba ọsọ ọsọ maka ikiri mmekọrịta.
Kedu ka Gaussian Splatting si anọchi anya ọnọdụ 3D?
Ihe nkiri a bụ igwe ojii doro anya nke 3D Gaussians, nke ọ bụla nwere ellipsoid na-enweghị isi nwere ọnọdụ, ọdịdị, oghere na agba.
Kedu ihe kpatara Gaussian na-agbaji ngwa ngwa inyefe karịa NeRF mbụ?
Ịmepụta na ịgwakọta blobs site na rasterization dabeere na tile na-ezere NeRF ji nwayọọ nwayọọ na-agba ọsọ kwa-pixel ray, na-enye ohere ọsọ ọsọ.
Kedu ozi Gaussian 3D ọ bụla na-echekwa?
Blọb nke ọ bụla na-ebu ọnọdụ, nnabata (nha na nghazi), opacity, na ozi agba.
Kedu ihe a na-eji mee ka ụcha blob gbanwee n'akuku nlele?
A na-ejikọta agba ya na harmonics spherical, yabụ Gaussian ọ bụla nwere ike ịpụta dị iche na ntụziaka dị iche iche, na-ewere ntụgharị uche.
Kedu ka ọzụzụ si ebido na Gaussian Splatting?
Ọ na-amalite site na obere isi ihe site na nhazi igwefoto na-emegharị ahụ, wee na-ebuli ndị Gaussian ebe ahụ.
