A study of generalization of dichromatic reflection model which is considered specular reflection component with the object color

面料中，按顺序构成的纱线是通过细小的极短纤维错综复杂地缠绕着纬纱和经纱制成的，用CG来表现外观并不容易。为了通过数值计算生成图像，甚至是像纺织品这样的复杂结构，研究了新的反射模型。在实验中，对放大后的光谱图像进行了微观层面的织造结构的测量。此外，它还图案化的光投影，以分离反射的全局分量和直接分量。实验结果，还包括光源颜色的轻微但直接反映的织物成分被发现，最淡化的物体颜色。这被认为是因为光源反射的光穿过纱线内部，发生了亚表面散射。

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.
