In order to solve the problem of fabric design and fabric applications divorced , convenient designers , the Customer Preview fabric in different contexts effect , the subject developed a three-dimensional fabric scene simulation system . Entered into the computer system to a variety of fabrics and scene pictures through the calculation process , to generate the realistic effect of the fabric in the scene , changed the original to rely on the designer imagination , the pure empirical product development for visualization and intuitive behavior , thus shortening design time , the development of marketable products . The main work of this paper : scene - based virtualization technology and realism algorithm the fabric scene simulation design and implementation . The program is mainly entered by the scene of three parts of the modules , pseudo - surface mesh module and photorealistic module : 1 . The scene input module , based on image binarization and chain code method the scene contour automatic extraction method to determine the simulation area , simplify the system of human interaction , to improve the accuracy of simulation area . Pseudo surface mesh module proposed the concept of the control vectors , the use of control vectors and bilinear interpolation mesh construction mesh model ; the grid dynamic adjustment methods to refine the mesh is made ??on this basis , a better reflects the original scene fold effect . Realistic module , combined with anti-aliasing technology , an easy programming , fast bilinear texture mapping interpolation algorithm ; use of image fusion algorithm based on the brightness and saturation of the scene image and texture image after pretreatment calculated according to the saturation and brightness of the corresponding phase prime point of the target area with the texture image , the color value of the corresponding point in the target area . The new algorithm to distinguish the texture of light and shade and scene of light and dark , and to avoid the distortion of the image color , to ensure the stability of the texture mapping results , achieve better realism Finally, based on the above research and software programming , software fabric 3D scene simulation system .
