Abstract


Appearance of analog functions of existing the woven fabrics CAD system can quickly obtain the fabric design look , but only for the analog part of the fabric , and lack of realism of its two-dimensional analog image , the appearance of realistic simulation of woven fabrics with a three-dimensional image has become a new research direction. This topic in computer graphics and software engineering knowledge as the theoretical basis for the application of textile expertise , in-depth analysis of the three-dimensional geometry of carpet yarn , velvet ring the three-dimensional geometry model , light material set combined geometric carpet space the model and the force model to achieve a three-dimensional computer simulation of the loop pile carpet . The specific study reads as follows: yarn simulation: First start from the several main factors affecting yarn color , yarn , twist , twist, light performance , the establishment of the yarn force model the simulated yarn centerline of the track , combined with lateral geometric features of the the Peirce model simulation yarn to give the yarn to establish a three-dimensional model of the yarn . Settings, combined with basic light material parameters of the yarn to simulate yarn realistic lighting effects to achieve the three-dimensional simulation of the yarn . The velvet ring analog : This article simplify velvet ring single yarn velvet circle refinement velvet circle table details the method to establish the model of the velvet ring . The velvet circle on the carpet is not arranged in accordance with the rules of design , velvet ring occurs dislocation , extrusion, and even the level of laps shelter . In the simulation of the overall effect of the carpet , these factors must be taken into account. Carpet simulation : Open Inventor 3D graphics system Phong illumination model model carpet surface of the fabric yarns . Combined with the surface of the yarn material , structure , twist and yarn fabric fabric color shading variation according to the intensity of the light source position , and finally simulate the appearance of the carpet fabric . Adjust the camera's position and orientation can be observed from different angles, the simulation results. Through this research method to simulate the appearance of the carpet fabric 3D simulation effect diagram and physical contrast , simulation figure able the realistic simulation carpet in the circle of high change , to achieve a two-dimensional analog simulation effect is difficult to achieve .
