| Research Abstract |
The fabric, in order constituted yarn are made complicatedly entangled weft and warp through thin very short fibers, and represent the appearance by CG is not easy. For generating image by numerical calculation, even complex structures such as textiles, the new reflection model was studied. In the experiment, the spectrum image enlarged woven structure of the micro-level until was measured. Further, it was also patterned light projection to separate the global component and the direct component of the reflection. The experimental results, also including the light source color slightly but directly reflected component of the fabric was found that the most tinged object colors. It is considered that this is because the reflected light from the light source passes through the interior of the yarn, the sub-surface scattering is taking place.
