Interactive Fabric Scene Simulation System Design

The scene simulating result is one of the required information to clients. Pictures gained by cameras are finite, and we cannot replace the scene optionally. If the scene simulating function is added to the textile CAD system, importing a lot of material of cloth and scenes into a computer and generating the effect of simulaing, producers can know the needs of clients in time and adjust the design to keep advantage in competition. Clients can provide their real scene pictures like furnishings in a house. by replacing the scene with different textile, producers can simulate upholstering in a virtual scene.This project aimed at developing some kind of such system. The application of this system could not only shorten the time and reduce the cost of cloth design, but also build a more efficient communication between cooperation and customers.To realize the reality and manipulation, this paper uses a single and quick method to build the scene quadrangular surface mesh model. The mesh region is fixed by the tendency of the mapped region, and the model is generated by dividing the edges of the mesh region on average and calculating inner parts in bilinear interpolation method. Then, a classical texture mapping method of bilinear interpolation is proposed to realize mapping from a rectangle to any quadrangle, using the idea of triangular mesh. Shading processing is also considered when we want to exactly simulate the cloth surface.The development of textile simulation, mesh building and texture mapping techniques and relative background are studied in the paper. The specific technical points and programming language frame are presented in Microsoft Visual C++ 6.0 programming language environment. Simulation result is good, so the design in this paper is feasible.
