In the computer graphic (CG) technology for indication of three-dimensional (3D) image of fabric surface, there is no indication method based on measured information to express precisely the fabric textures with reflection of anisotropy. We analyzed the regulations of the reflection on fabric surface with anisotropy, and tried to express the results by CG. Two kinds of twill woven and the plain woven are chosen as the sample. We think fabric surface consists of many tiny surfaces with different attitude of surface. This surface attitude was indicated using γ of tilt angle (similar incident angle), and θ of angle between warp direction and tilt direction. Surface textures were extracted from measured images with various attitudes (γ, θ). A texture consists of character of luminance such as reflection luminosity, irregularity of luminosity, and a diagonal pattern. From the results, the relationships among three characters and attitude (γ, θ) was understood. Texture was generated using look-up-table calculated with interpolation method from measured data. Also, fabric surface image with reflection of anisotropy by 3D-CG was generated using texture-mapping method with volume texture. When three kinds of generated images are compared with other images, it is clear that the texture with reflection of anisotropy is expressed.
