Texture Gradients - Objects that are farther away appear rougher and appear to have more detailed textures.

纹理梯度——远处的物品会显得粗糙，并可以看到更多的纹理细节。

I am mostly interested in introducing texture and depth to diagrams that are typically presented in a more simplified manner using solid colors and no gradients.

我最感兴趣的就是在图中引入纹理和深度，通常是用单色和非渐变色这种更简单的方式将其表现出来。
