填充曲线

填充曲线 节点使用以曲线为边界的受约束的 Delaunay 三角化算法生成网格。网格仅生成平面，局部Z轴为0。

输入

曲线

标准的几何图形输入。

群组 ID

Value used to group curves together. Curves with different Group ID are treated separately.

属性

模式

指定输入/输出类型。

• 三角形:

  输出由三角形组成。

  多边形:

  输出由n-gons组成。

输出

网格

The filled-in curves.

示例

Customized triangulation

One or many “single point spline” can be used to customize the triangulation of the filled-in curves.

This is the default behavior of the Fill Curve node applied to the star primitive.

Here, a single curve point is joined to the star primitive to customize the triangulation.

Here, 300 single curve point are joined to the star primitive to customize the triangulation.

群组 ID

The following figures display diverse application of the Group ID.

Here, the 4 curves share the same Group ID, resulting in 1 mesh island (default behavior).

Here, the 4 curves have different Group ID, resulting in 4 mesh islands.

Here, the 4 curves are seperated into two groups based on their positions, resulting in 2 mesh islands.
