摘要：We propose a method for modeling human skin including macules and show the rendering results. This method is intended especially for applications in dermatology and cosmetics. Our model is based on volumetric representation. It consists of nine layers classified by the difference in optical properties. The surface normals and the number of voxels of each layer are derived from measurement data of the real skin surface. Each voxel has a type of layer that indicates the values of the optical parameters. The density distributions of the melanin in the macules are defined by a gray-scale image. We use photon mapping for rendering to consider multiple scattering and spectral attenuation. Rendered images with or without macules can successfully reproduce the color, and the spectral reflectance is also shown.
