Research & Design On The Method Of Fabric Appearance Simulation

Applying CAD to textile designation, using computer software to design textilepattern, the technique of fabric simulation can generate realistic appearance of all kinds of fabrics.With the application of fabric simulation technique, textile designationbecomes quite easy and effective; designer will be released from multifarious and trivial labor and have more time or energy to engage in conceiving production; you can obtain realistic textile pictures and need not to weave out it actually, this will lead to a great many benefits: shorten produce period rapidly, reduce running expense sharply, fasten enterprise's reaction to marketing, make convenient for information communication and producers will free from motiveless manufacture. Along with wild employment of electronic business, producers can utilize Internet to put out newly products, do business and intercommunication. Therefore, the producer will be more competitive.The technique of fabric simulation has been wildly accept and put into useoverseas. But inside China, there is only a fraction of fabric manufacturers take advantage of CAD technique during designation and production. And the marketing occupation of this software is still at a comparatively low level. In the respect of fabric simulation research and development, institutions overseas started off earlier, and have put out some commercial software; while the software in domestic is however just at the experimental phase.This paper demonstrates a system based on 2-dimension, which implementplain fabric simulation. According to fabricate criterion, viewing thread as the basic unit, we generate the textile pictures by arranging threads, and crossing warps and wefts. This system renders textile designers change all the fabric properties freely, and express ones' ideas incisively and vividly. Meanwhile, this paper emphasizes the display algorithm of tightly arranged threadsoverlap, thread picture simulation and feather generation. In succession, we stretch the simulating environment into 3-dimension. Structuring a simple model by patching up Bezier covers to figure the surface of a single thread, putting forward an accurate method to display the shape of thread interlacing, we simulated the tabby fabric.
