平滑毛发曲线

The Smooth Hair Curves node relaxes and evens out the shape of hair curves by averaging their control points over multiple iterations. It is useful for reducing noise, smoothing deformation artifacts, or refining groomed hair shapes after other operations such as frizz or noise deformation.

输入

几何数据

The input geometry containing the hair curves to smooth.

数量

Controls the strength of the smoothing operation. Positive values smooth the curves by averaging point positions. Negative values exaggerate the differences between points, creating a crumpled or distorted effect.

形状

Defines how the smoothing influence changes along the curve length. A value of 0.0 applies a constant effect, while 0.5 results in a linear falloff from root to tip.

迭代

The number of smoothing steps applied. Increasing this value produces smoother results but may increase processing time.

权重

A per-point weighting factor that controls how much each point contributes to the smoothing. Values closer to 0 reduce smoothing influence at those points.

锁定发梢

When enabled, the tips of the curves remain fixed, preventing them from moving during smoothing.

维持长度

When enabled, maintains the original length of each curve during deformation. When disabled, smoothing may slightly shorten the curves.

输出

几何数据

The resulting geometry with smoothed hair curves.
