曲线控制点

曲线到点 节点从曲线生成点云。

输入

曲线

标准法向输入。

数量

生成的点数。此输入仅适用于 计数 模式。

长度

曲线的长度。此输入仅适用于 长度 模式。

属性

模式

已解算

Creates points from the curve's evaluated points based on the resolution attribute for NURBS and Bézier splines. This mode will generally be the fastest, since the second step of sampling equal lengths is not necessary.

数量

通过均匀分布指定数量的点对每根样条线进行采样

长度

Sample each spline by splitting it into segments with specified length. The length will be rounded down so that a whole number of samples will fit in each input spline. To counteract jumping when the length of the spline changes, the 修剪 can be used with a multiple of this length.

输出

点

点云的点

切向（正切）

The normalized curve tangent at the sampled position, or the direct evaluated normal in Evaluated mode.

法线

The normal value from the evaluated curve at each result point. This is the same value from the 法线节点 at those positions.
