插值曲线

Generate new curves on points by interpolating between existing curves. This is useful to have a smaller set of original curves to make editing easier and faster while still generating high-density curves for the viewport or a final render.

输入

引导曲线

新曲线在其间插值的基础曲线。

引导朝上

Optional up vector that is typically a surface normal. Supplying an up vector will improve the quality of the interpolation, making it aware of the surface shape which it otherwise wouldn't have a way to know about.

Tip

In a typical "child hair" generation setup, this up direction is retrieved with a combination of the 采样UV表面 using the same geometry that the points were distributed on, and the 法向节点.

引导群组 ID

Splits guides into separate groups. New curves interpolate existing curves from a single group. This input can be useful for generating hair parts by stopping curves in different sections (with different group IDs) from affecting each other.

点

The positions of the first root control points of the newly generated interpolated curves.

点朝上

可选朝上矢量，通常是表面法向。

点群组 ID

要插值的曲线组。

最大邻项

插值时考虑的邻近引导曲线最大量。

属性

该节点没有属性。

输出

曲线

The guide curves with interpolated curves.

最近编号

每个生成的曲线的最近引导曲线编号。

Note

Internally this node mixes the data from multiple guide curves, with the maximum number of sources depending on the Max Neighbor input. This output is only the index of the curve with the largest weight.

最近权重

每条生成的曲线的最近引导曲线的权重。
