Abstract:

In order to solve the problem on difficult prediction of digital yarn appearance caused by the complicated color matching of yarn, a simulation method based on fiber unit was presented to complete the simulationof digital yarn. First of all, the texture model of fiber was constructed based on the rawmaterial color values of digital fiber. Secondly, digital yarn appearance area color piece based on the spinning process parameters were calculated. Thirdly, the gradient model was built by using the principle of gradual changes between different components and combining with lighting model simulation luminance information. Finally, the real digital yarn diameter and peofile were collected. It can simulate the different components and color of digital yarn deeping the color and composition unchanged. The results show that the proposed yarn simulataion method xan simulate the appearance of the digital yarn quickly, and the appearance of the vision is very close to the actual digital yaaran, laying a solid foundation for the development of digital yarn and fabric simulation.

Key words: kigital yarn, fiber unit, arrangement about color piece, texture modal, diameter peofile, illumination model
