abstract     : Point-based graphics has gained much attention as an alternative to polygon-based approaches because of its
simplicity and flexibility. However, current point-based techniques do not provide a sufficient rendering quality
for translucent materials such as human skin. In this paper, we propose a point-based framework with subsurface
scattering of light, which is important to create the soft and semi-translucent appearance of human skin. To
accurately simulate subsurface scattering in multilayered materials, we present splat-based diffusion to apply a
linear combination of several Gaussian basis functions to each surfel in object space. Compared to existing pointbased
approaches, our method offers a significantly improved visual quality in rendering human faces and provides
a similar visual quality to polygon-based rendering using the texture space diffusion technique. We demonstrate
the effectiveness of our approach in rendering scanned faces realistically.
