Points of Curve Node

The Points of Curve node retrieves indices of specific control points in a curve.

输入

Curve Index

The index of the input curve.

Note

By default this uses the index from the field context, which makes it important that the node is evaluated on the curve domain.

权重

Values used to sort the curve’s control points. By default the control points are sorted by index, so the control points with the smallest indices come first.

Sort Index

Which of the sorted control points to use for the Point Index output. If the value is larger than the total number of control points, it will wrap around to the beginning.

属性

这个节点没有属性。

输出

Point Index

The index of one of the curve’s control points, chosen by the Sort Index input.

总数

The number of control points in the curve.
