This lets you optimize geometry, materials, lighting, and camera using gradient descent.

Rendering bu mëna wuutale dafay soppi loolu ci xayma ni pixel bu nekk ci génne di soppikoo ci parametru duggal bu nekk. Ak degrade yooyu, optimisatër bi mën na xawa jekkal jëmm 3D wala ay texturam ba nataal bi ñuy render méngoo ak nataal biñ bëgga joxe, muy xol rendu bu dëddu ak jàngat-ci-synthese. Jafe-jafe bi gëna mag mooy rendu bi dafay ànd ak discontinuité, rawatina ci silhouette yi ak ci catu occlusion yi, fu pixel bi di tëb ci saasi joge ci kanam dem ci ginaaw.

What is Differentiable Rendering?
Rendering buñ mëna wuutale dafay tax anam wi ñuy soppi seen 3D nekk nataalu 2D mën nañu ko wuutale bu baax, suko defee nga mëna xayma degrade yi tàmbalee ci pixel yiñ rendu ba ci parametru seen yi. Loolu daf lay may nga gëna mëna jëfandikoo geometrie, macceer, leeraay ak kamera ci jëfandikoo wàccinu gradient.
Lan mooy rendu differensiaal bi lay may nga xayma?
Soo defee rendu bi wuute, dinga am gradient yuy joge ci pixel yi dellu ci dugal seen, loolu mooy tax ñu mëna jëfandikoo gradient bi.
Lan moo waral silwet yi nekk jafe-jafe bu mag ci rendu buñ mëna wuutale?
Ci silhouette bi, pixel bi dafay jàpp ci diggante kanam gi ak ginaaw gi, kon derivatif bu naïf bi amul benn leeral wala amul benn leeral ci jëmm ji.
naka la rasterization bu woyof di saafaraa jafe-jafe discontinuité bi?
Rasterisation bu woyof (lu melni, SoftRas) dafay yombal coverage bi suko defee triangle bu nekk mëna am njeexital ci pixel yi ko wër, di defar ay gradient yuñ mëna jëfandikoo.
Luy 'rendering inverse'?
Rendu inverse dafay jëfandikoo rendu buñ mëna wuutale ngir gëna baaxal parametru seen yi ba nataal biñ defar méngoo ak nataal biñ xool.
Ban pexem modern moo sukkandiko ci rendu bu wuute ngir tàggat yaram?
