映射范围节点

The Map Range node remaps a value from a range to a target range.

输入

明度: 要重映射的输入值。
从最小值: 重映射前数值范围下界。
从最大值: 重映射前数值范围上界。
到最小值: 目标范围的下界。
到最大值: 目标范围上界。
步数(阶梯): The number of values allowed between To Min and To Max when using Stepped Linear interpolation. A higher value will give a smoother interpolation while lower values will progressively quantize the input.

插值类型

The mathematical method used to transition between gaps in the numerical inputs.

线性: Linear interpolation between From Min and From Max values.
阶梯线性: Stepped linear interpolation between From Min and From Max values.
平滑步骤: Smooth Hermite edge interpolation between From Min and From Max values.
更平滑步骤: Smoother Hermite edge interpolation between From Min and From Max values.

钳制

启用后，输出将被钳制到目标范围。

噪波纹理 节点输出范围为 [0, 1]。我们可以使用 映射范围 节点将其重新映射到范围 [-1, 1]。
