Abstract:

Aiming at the problems that the digital yarn has various colors, complex changes and long color change cycles, causing the difficult reflecting on the characteristics of digital yarn for the conventional yarn simulation method, which is usually used in short cycle yarn simualtion. Therefore, a digital blackboard yarn simulation method reflecting the long-cycle digital yarn’s features was proposed. The simulation method took the most representative gradient color yarn as the simulated example, used different color patches as the basic unit and arranged these units in series according to the gradient color yarn color ratio change regulation to form the entire yarn. Finally, the simulated digital yarn was segmented into the digital blackboard to show the overall appearance of the gradient color yarn color change feature. This simulation method can accurately reflect the long-cycle digital yarn change feature, and give the yarn a certain sense of reality.

Key words: digital yarn, gradient color yarn, digital blackboard, yarn appearance, color simulation
