Abstract:

In order to improve simulation of warp knitted plush fabrics, an approach based on fractal noise and geometry shader was proposed to solve the roblem of stiff or messy plush when defining the direction as consistent tangential or completely random. The randomness of plush using fractal noise was calculated, and then the  generated fractal noise was as a texture to feed the GPU for further adjustment. A set of chips along the tangential direction of plush were used to represent a plush. According to the relation between the tangential direction of the plush and the observation, two different chips were defined to ensure displaying continuous plush at any viewpoint. 3-D simulation of warp knitted plush fabric was realized by using a geometry shader of GPU. Comparison with real fabrics, the approach is proved superiorly naturalistic with real-time efficiency.
