缩裹毛发曲线

The Shrinkwrap Hair Curves node projects hair curves onto a target surface, adjusting their positions so they follow the shape of a mesh. It can be used to conform hair to a scalp or other underlying geometry, ensuring curves remain properly positioned relative to a surface.

输入

几何数据

The input geometry containing the hair curves to be shrinkwrapped.

表面输入类型

Determines how the surface data is provided for shrinkwrapping. The geometry input takes priority over the object input.

物体:

Use an object reference to sample the target surface.

几何数据:

Use a geometry input to sample the surface directly.

曲面

The surface object or geometry used as the target for the shrinkwrap projection.

系数

Controls the overall influence of the shrinkwrap effect. A value of 0.0 leaves the hair unchanged, while 1.0 fully conforms the hair to the surface.

偏移距离

Defines a distance offset from the target surface. Positive values move curves away from the surface, while negative values move them inward.

表面上方

Blends the shrinkwrap effect for points that start above the surface, allowing smoother transitions when only some parts of the curve should adhere to the mesh.

平滑步数

The number of smoothing iterations applied to the curves after shrinkwrapping. Increasing this value helps to reduce artifacts and achieve smoother results.

锁定发根

When enabled, prevents the root points of each curve from moving during the shrinkwrap operation. This ensures hair roots remain fixed to their original positions (e.g., attached to a scalp).

输出

几何数据

The resulting geometry with curves conformed to the target surface.
