Noise Shader

Noise is a special type of channel shader that produces 32 types of noise. The shader can calculate the noise in 2D (Space set to UV 2D) or in 3D space. The advantage of 3D noise is that you don’t have to worry about mapping or seams in the texture.

噪波是一种特殊类型的通道着色器，可产生32种类型的噪声。着色器可以在2D (空间设置为UV 2D) 或3D空间中计算噪波。3D噪波的优点是您不必担心纹理中的映射或接缝。

Noise is an integral component of any render system because it turns an otherwise far too smooth surface into a more or less randomly uneven surface (e.g., when used in the Bump channel). Below are examples of all Noise types available in the Noise Shader. Their respective effects are shown using Sub Polygon Displacement.

噪点是任何渲染系统中不可或缺的组成部分，因为它可以将原本过于光滑的表面变成或多或少的随机不平整的表面（例如，在凹凸通道中使用时）。下面是噪声着色器中所有噪声类型的例子。它们各自的效果是用子多边形位移[Sub Polygon Displacement]来显示的。 [Sub Polygon Displacement] 类似于 RS物体标签中的 Geometry👉Tessellation
