偏移曲线中的点

The Offset Point in Curve node retrieves other points in the same curve as the input control point. This is like starting at a specific control point and walking along neighboring points toward the start or end of the curve.

Conceptually the operation is similar to the 面内拐角偏移, but the point index doesn't wrap around to the other end of the curve unless it is cyclic.

输入

点编号

输入控制点的编号。

Note

默认情况下，这会使用场上下文中的编号，因此节点必须在点域上进行解算。

偏移

The number of points to move around the curve before finding the result. If the curve is cyclic and the offset goes past the start or end point of the curve, it will wrap around to the other side.

输出

是否有效的偏移

Whether the input control point plus the offset is a valid index of the original curve. Any offset in a cyclic curve is always valid.
