A Fast and Layered Real Rendering Method for Human Face Model - D-BRDF

Accurate rendering a real-world object has been a long-standing challenge in computer graphics area. The most popular method is BRDF, it is valid for opaque materials, such as metals, but it fails for translucent materials, such as skin. In order to render human skin faster and better, we propose a layered method D-BRDF, which divides the face model into three layers: sebum, epidermis and dermis, and combines the ambient light, specular reflection of sebum, diffuse reflection of the epidermis and subsurface scattering of the dermis to get the sum of light intensity and the final rendering effect. We experiment on several models, and the results show that it is more effective and faster than BRDF working on translucent models. The effects are downy and transparent, especially in the ear, cheek and other details. And it can be widely used in other related areas.
