毛发曲线噪波

The Hair Curves Noise node adds procedural noise-based deformation to hair curves, creating natural-looking randomness or turbulence. This can be used to simulate effects such as wind disturbance, curly or wavy hair, or subtle irregularities in a groom.

输入

几何数据

The input geometry containing the hair curves to deform.

累积偏移

When enabled, each point's offset is influenced by the displacement of the preceding points along the curve. This produces smoother and more continuous bending rather than independent point motion.

系数

Controls the overall intensity of the noise deformation. A value of 0.0 disables the effect, while 1.0 applies the full displacement.

距离

Multiplies the amplitude of the noise displacement. Higher values increase how far the hair is moved from its original shape.

形状

Defines the variation of the effect along the curve length. A value of 0.0 applies a constant deformation, while 0.5 produces a linear falloff from root to tip.

缩放

Adjusts the scale of the noise texture based on the root position of each curve. Smaller values create larger, smoother waves, while higher values produce finer detail.

沿曲线缩放

Defines the frequency of the noise along each individual curve. Higher values create tighter, more frequent variations along the hair strands.

每条曲线的偏移

Adds a random offset to the noise pattern for each curve. This ensures that each hair receives a unique noise variation.

随机种

Sets the random seed used to initialize the noise pattern. Changing this value produces different random results while maintaining the same parameters.

维持长度

When enabled, maintains the original length of each curve segment during deformation. When disabled, noise deformation may stretch or compress the curve slightly.

输出

几何数据

The resulting geometry with the noise deformation applied to the hair curves.

偏移矢量

The vector field indicating the displacement applied to each point along the curves.
