2）Modeling and rendering of 3d wrinkle texture in Chinese ink landscape painting

Cow-hair wrinkle texture: Cow-hair texturing in traditional landscape painting is a kind of brushwork lines similar to cow hair. In Maya, we try to simulate the 3D modeling and rendering of Cow-hair wrinkle texture by changing the linear way of particle stacking and the randomness of density and staggered distribution. In addition, we set the color of Cow-hair wrinkle texture according to the needs. The upper Color 1 is set as the ochre stone color in the color of Chinese painting, and the lower Color 2 is set as the ink color. Through gradual blending, this effect is very similar to the traditional Light-color ink painting method. The final effect is shown in Figure 12:
