我们介绍了几种模拟日本漆器的方法，日本漆器是远东地区一种著名的手工艺艺术。我们考虑了两种最受欢迎的日本漆器，它们是由Makie和Nashiji工艺制成的。对于Makie的渲染，我们提出了一种从艺术品的数字照片中制备RGBA纹理的方法。这些纹理的Alpha通道控制颜色通道与测量的金属抛光双向反射分布函数(BRDF)混合的权重。同时演示了光线跟踪和基于硬件的渲染。在后一种情况下，我们展示了如何使用用于列表BRDF的特殊坐标系来加速用于BRDF可视化的球面贴图纹理的计算。通过对浸泡在吸波材料中的金属薄片的显式建模，模拟了那氏漆所表现出的深度效应。
We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques. For rendering makie, we propose a method for preparing RGBA textures from digital photos of art items. The alpha channels of these textures control the weight with which color channels are blended with the measured biderectional reflectance distribution function (BRDF) of a metallic finish. Both ray tracing and hardware based rendering are demonstrated. In the latter case, we show how the calculation of a sphere map texture used for BRDF visualization can be accelerated using a special coordinate system for tabulated BRDF. The depth effect manifested by nashiji lacquer is simulated by the explicit modeling of metal platelets immersed in absorptive material.
