Abstract
Translucent objects are very common in the real world, so the real-time rendering of the translucent objects is a hot research topic in recent years. However, because of the special properties and translucent material and the complexity of interaction with light, it is too difficult to achieve both realistic and real-time. This paper proposes a real-time subsurface scattering rendering method for translucent objects. In the paper, a method of illumination model decomposition for subsurface scattering is proposed first. And then use the BRDF model to approximate the illumination of single subsurface scattering, at the same time improve the traditional rendering equation of the multiple subsurface scattering. Using the technology of deferred shading and parallel computing capability of GPU, which has reduced the integral computation during rendering. This paper has achieved the real-time rendering of subsurface scattering for translucent object without affect the final rendering effect.
