In the teaching courseware of"Fabric Structure and Design",computer animation technology is used to realize the dynamic simulation of fabric composition,and the drawing process of chaine and weft interweaving and the fabric composition process are displayed in the animation process.Taking the simulation process of a trademark graphic weaving as an example,it is used in the courseware of"Fabric Structure and Design",which can realistically display the whole process of its graphic composition.This kind of computer animation technology that realizes the dynamic simulation of fabric composition is applied to the composition of other graphics in the course of"Fabric Structure and Design",and a series of courseware for the teaching of"Fabric Structure and Design"is completed.
