Title:

    Which BSSRDF model is better for Heterogeneous Materials?

Presenter(s):



Abstract:


    We present an improved method for rendering heterogeneous translucent materials with existing BSSRDF models. In the general BSSRDF models, the optical properties of the target object are constant. Sone et al. have proposed a method to combine with existing BSSRDF models for rendering heterogeneous materials. However, the method generates more bright and blurred images compared with correctly simulated images. We have experimented with various BSSRDF models by the method and rendered heterogeneous materials. As a result, the rendered image with the better dipole model is the closest to the result of Monte carlo simulation. If incorporating the better dipole model into the method proposed by Sone et al., we can render more realistic images of heterogeneous materials.
