Rendering Methods of Special Clothing Fabrics

Clothing design is one of the development directions of garment industry in recent years. The materials of clothing fabrics are extremely diverse while physically-based rendering has major limitations. Based on this, this article studies a variety of fabrics with special optical properties. The special fabrics studied are four kinds of fabrics: metal wire hybrid fabrics, fabric with side light, laser fabrics and glitter fabrics. For metal wire hybrid fabrics, this article uses additional texture data to record and simulate the shape of the metal wire; for fabric with side light, this article corrects the intensity of the scattered light according to the direction of the line of sight and the angle between the incident direction and the normal, so that the fabric has a more real sense of side light; for laser fabrics, this article associates the viewing angle with an additional laser color, which is blended with the original texture color. For glitter fabrics, this article proposes a calculation model for randomly generating the position of glitters and the model can achieve real-time calculation efficiency through grid division. After comparing the rendering results of the algorithm in this article with the actual shooting results, it can be found that the rendering results are close to the real. The side light fabrics materials as well as the laser fabrics materials have been used in the three-dimensional clothing design software Style3D.
