置换毛发曲线

The Displace Hair Curves node offsets the shape or position of hair curves using a displacement vector. This allows for procedural control over hair movement, direction, or surface alignment. The displacement can be applied in object, world, or surface normal space, depending on the configuration.

输入

几何数据

The input geometry containing the hair curves to displace.

系数

Scales the overall displacement strength. A value of 0.0 applies no displacement, while 1.0 applies the full displacement vector.

形状

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

物体空间

The object whose transform defines the coordinate space of the displacement. If unset, displacement is applied in the modifier's local space.

置换矢量

The vector used to determine the direction and magnitude of the displacement. This can be driven by fields or other procedural inputs.

表面法线

When enabled, displaces the curves along the normal of a surface, allowing for effects like "pushing" or "lifting" hair away from a mesh.

Can be enabled from the header.

表面输入类型

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

物体:

Use an object reference to sample surface normals.

几何数据:

Use a geometry input to sample normals directly.

曲面

The surface object used to sample the normals for displacement.

表面UV映射

The UV map used when sampling the surface normals for displacement.

表面法线置换

Amount of displacement applied along the sampled surface normal. Can be positive or negative depending on the desired direction.

输出

几何数据

The resulting geometry with displaced hair curves.
