Gaussian
Gaussian Splatting yerekana ishusho ya 3D nka miriyoni ntoya, amabara, igice-kibonerana gishobora gutangwa mugihe nyacyo.
Incamake
It delivers NeRF-like photorealism while running fast enough for interactive viewing.
Kwibira cyane
Yerekanwe kuri SIGGRAPH 2023, 3D Gaussian Splatting yubaka amashusho yifoto nka NeRF ariko ikoresha ishusho yerekana aho gukoresha umuyoboro wihishe. Buri gice ni igicu cyaba Gaussiya ya 3D, blobs ya fuzzy ellipsoidal, kandi buri blob ibika umwanya, ingano nicyerekezo (covariance yayo), opacite, nibara. Aho kurasa buhoro buhoro imirasire binyuze murusobe, uburyo "busasa" utwo tubuto kuri ecran hanyuma ukabihuza, inzira yegereye rasterisation gakondo bityo rero byihuse. Amahugurwa atangirira ku gicu gike gikozwe na kalibibasi ya kamera, hanyuma igahindura blobs mugihe uhuza noguhuza amakuru arambuye aho ibibanza bitarubakwa kandi bigacibwa aho bituwe cyane. Igisubizo nigihe-cyerekana kuri 1080p hamwe nubwiza burwanya NeRFs nziza, niyo mpamvu ikwirakwira vuba binyuze mubishushanyo no gufata ibikoresho.
Ubushishozi
Urufunguzo ni tile itandukanye ishingiye kuri rasterizer. 3D Gaussiya iteganijwe kugera kuri 2D, itondekanya kubwimbitse, hamwe na alfa ivangwa kuri ecran ya tile, bityo rero gutanga birinda kugenda kuri buri pigiseli ya rayon ituma NeRF itinda. Ibara ryabitswe hamwe nuburinganire, kureka buri blob igahinduka igaragara hamwe no kureba inguni kugirango ifate ibitekerezo. Kuberako umuyoboro wose utandukanye, ifoto imwe ihuye na gradient descente ikoreshwa na NeRF ihindura imyanya ya blob, imiterere, opacite, namabara, mugihe intambwe yo gukura ikura cyangwa igabanya abanya Gaussiya kugirango bongereho amakuru yabuze.

Ejo hazaza ha Gaussian Splatting
Gaussian Splatting iragenda yihuta kuva mubushakashatsi mubicuruzwa byo gufata 3D, gushushanya, no kubyaza umusaruro, igice kuko bitanga mugihe nyacyo kubakoresha GPU ndetse nabashakisha. Intego yibikorwa yibikorwa bigabanya ingano ya dosiye (amashusho arashobora kuba manini), gukora ibintu bigenda neza kandi bifatika, kwerekana, no guhindura ibintu kugiti cye. Tegereza guhuza cyane na moteri yimikino na AR / VR, uburyo bwimvange buhuza ibice na meshes, no gufata amashusho ya terefone. Biragenda bigaragara nkibintu bifatika byuzuzanya, cyangwa gusimbuza, NeRF ahantu hose byihuta byingirakamaro.

What is Gaussian Splatting?
Gaussian Splatting yerekana ishusho ya 3D nka miriyoni ntoya, amabara, igice-kibonerana gishobora gutangwa mugihe nyacyo. Itanga NeRF isa na Photorealism mugihe ikora byihuse kugirango turebe.
Nigute Gaussian Splatting igereranya 3D?
Ibyerekanwe ni igicu kigaragara cyaba Gaussiya ya 3D, buri kimwe cya ellipsoid ya fuzzy ifite umwanya, imiterere, ububobere, nibara.
Kuki Gaussian Splatting yihuta cyane gutanga kuruta NeRF yumwimerere?
Gutegura no kuvanga blobs ukoresheje tile ishingiye kuri rasterisation irinda NeRF gahoro gahoro kuri pigiseli ya ray igenda, bigatuma umuvuduko wigihe.
Ni ayahe makuru buri 3D ya Gaussian ibika?
Buri blob itwara umwanya, covariance (ingano nicyerekezo), idasobanutse, namakuru yamabara.
Niki gikoreshwa kugirango ureke ibara rya blob rihindurwe hamwe no kureba inguni?
Ibara ryuzuyemo imiterere ihuza, bityo buri Gaussian irashobora kugaragara itandukanye nicyerekezo gitandukanye, ifata ibitekerezo.
Nigute imyitozo itangirira muri Gaussian Splatting?
Itangirana ningingo zidasanzwe uhereye kumiterere-kuva-yerekana kamera ya kalibrasi, hanyuma igahindura abanya Gaussiya kuva aho.
