Deferred Shading in Luma

Luma is Floored’s in-house, browser-based solution for rendering interior architectural spaces. Interior architectural visualization brings with it the challenge of illuminating a variety of clean, real-world materials with many distinct, localized light sources. Like a number of its contemporaries, Luma tackles these challenges with deferred shading [Geldreich 04] complemented by physically based shading [Hill 13]. Luma’s implementation is flexible enough to be used for both traditional photorealistic rendering, as well as stylized rendering [Wei 14].
