Abstract:

To provide rapid CAD of the flat knitted fabric with more lifelike loop primitives, geometric model and the variation of the texture at the surface of the loop are studied. The model that captures the texture variation from the flat yarn to the bent loop is constructed to form the lifelike texture of the loop. And the lifelikeness of the loop with varying illuminations is optimized. The computer program is developed with the optimization algorithm. The loop texture of different yarns is simulated to prove the feasibility of the proposed algorithm. Our work provides rapid CAD of loop structure in the knitted fabric with a loop primitive simulation method that is not only more lifelike but also supports material adjustment of the yarn. This paper also provide theoretical value for the flat knitting fabric computer simulation.

Key words: flat knitting, yarn texture, rapid simulation, loop primitive
