The directional reflection characteristics of fabrics with various texture structures is an important and challenging topic in computer graphics and visual simulation. In the present study, the Bidirectional Reflectance Distribution Function (BRDF) of four different textured fabrics is measured via a self-designed Scatterometry to analyze the effect of surface textures and illuminated wavelengths. Furthermore, a fast and simple BRDF model is provided, and optimal model parameters for fabric BRDF calculation were obtained via a genetic algorithm. The results indicate that the reflected distribution of fabrics is dominated by diffuse reflection and is modulated by surface textures and irradiated wavelengths.
