Development of a rendering model of sub-surface scattering to visualize optical effects super-realistically

我们开发了一种亚表面散射渲染模型和一种超越传统低动态图像（LDRIs）的超逼真图像显示方法。建立了同时考虑单次和二阶散射的亚表面散射模拟方法，计算了改变入射角度和散射参数的亚表面散射辐照度分布。在此基础上，利用高动态范围图像（HDRI）对辐照度分布进行了精确插值，并得到了逼真的显示。

We have developed a rendering model for sub-surface scattering and a display method for super-realistic images beyond traditional low dynamic images (LDRIs). A simulation method for sub-surface scattering considering not only single but also second order scattering is constructed, and sub-surface scattering irradiance distributions are calculated altering an incident angle and scattering parameters of materials. Based on the investigation, the irradiance distributions are accurately interpolated and are displayed realistically using a high dynamic range image (HDRI).
