Akanya-NGP Hash Encoding
Instant-NGP nubuhanga bwa NVIDIA butoza Neural Radiance Fields hamwe nubundi buryo bwa neural graphique primitives mumasegonda aho kuba amasaha ubika ibintu byize mumeza ya hashire.
Incamake
It matters because it made high-quality 3D scene capture fast enough to feel almost interactive.
Kwibira cyane
Ako kanya Neural Graphics Primitives (NVIDIA, 2022) yibasiye icyuho nyamukuru cya NeRFs: MLP nini igomba kubazwa inshuro miriyoni. Aho kugirango ushireho umwanya wa 3D hamwe nibintu bya sinusoidal bihamye kandi wishingikirije kumurongo munini, Instant-NGP ikoresha multodeolution hash encoding. Umwanya utwikiriwe na gride nyinshi kumyanzuro itandukanye; buri gride ya selile ikarita, binyuze mumikorere ya hash umwanya, mumeza yegeranye yibintu byiga byerekanwa. Kugirango ushireho ingingo, sisitemu ireba hejuru kandi igahuza inyabutatu kuva kuri buri rwego rwo gukemura, ikayihuza, ikanagaburira muri MLP nto. Kuberako ibyinshi byize byerekanwe bibaho mumeza yo gushakisha kandi hasigaye urusobe ruto gusa, imyitozo no gutanga bihinduka gahunda yubunini bwihuse, akenshi bihindura amasaha mumasegonda.
Ubushishozi
Igice cyubwenge ni ukureka hash kugongana bibaho kubushake. Imbonerahamwe ya hash ifite ubunini butajegajega, bityo selile nyinshi zishobora gushushanya ikarita imwe; utuntu duto twa MLP hamwe na gradient descente biga gutandukanya kugongana kuko ingenzi, uturere twinshi cyane zitanga imbaraga zikomeye kandi zigatsinda neza imyanya isangiwe. Urwego rwa Multiresolution rusobanura urwego ruto rutagongana mugihe urwego rwiza rusangiye ibyinjira, kuringaniza ibisobanuro birwanya kwibuka.

Kazoza Kahita-NGP Hash Encoding
Kode ya Hash-grid yahindutse inyubako isanzwe irenze iyambere ya NeRF yerekanwe, ikoreshwa mugihe nyacyo cyo kureba synthesis, SDF na gigapixel-ishusho ikwiranye, kwigana, kandi nkumugongo wibikoresho nka Nerfstudio. Mugihe Gaussian Splatting ubu irushanwe kumuvuduko wo gutanga mbisi, kodegisi ya hash ikomeza kuba hagati aho hakenewe imirima yoroheje, yoroshye, ibazwa, kandi imirimo ikomeza ihuza byombi kandi igasunika ahantu hanini, hafite imbaraga, kandi bigenda neza.

What is Instant-NGP Hash Encoding?
Instant-NGP nubuhanga bwa NVIDIA butoza Neural Radiance Fields hamwe nubundi buryo bwa neural graphique primitives mumasegonda aho kuba amasaha ubika ibintu byize mumeza ya hashire. Nibyingenzi kuko byatumye 3D-nziza yo mu rwego rwo hejuru ifata byihuse bihagije kugirango wumve hafi.
Ni ubuhe butumwa bukomeye muri NeRFs ya kera-Intego ya NGP?
Classic NeRFs yishingikiriza kuri MLP nini yabajijwe kenshi; Ako kanya-NGP igabanuka ikora kugirango yihutishe amahugurwa no gutanga.
Ni hehe Instant-NGP ibika byinshi mubipimo byayo byiga?
Ibintu byiga bibaho mubuzima bwa multiresolution hash kumeza, hasigara akantu gato MLP kugirango uhuze ibintu bisa.
Nigute ibintu byahujwe murwego rwinshi rwo gukemura?
Urwego rwose ruranga ruri hagati ya trilinearly kandi rugahuzwa mbere yo koherezwa kuri MLP nto.
Nigute Instant-NGP ikemura hash kugongana mumeza yayo neza?
Biremewe kugongana; uturere twinshi cyane utanga imbaraga zikomeye kuburyo MLP ntoya hamwe na optimizasiyo yiga gukemura ibibanza bisangiwe.
Hafi ya Instant-NGP yihutisha amahugurwa ya NeRF angahe?
Kwimura ibyerekanwe mumeza ya hash no kugabanya MLP, imyitozo yatwaye amasaha irashobora kurangiza mumasegonda.
