填充曲线#
![填充曲线。](../../../../_images/node-types_GeometryNodeFillCurve.webp)
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
已填充的曲线。
示例#
自定义三角化#
One or many "single point spline" can be used to customize the triangulation of the filled-in curves.
![../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_0.png](../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_0.png)
This is the default behavior of the Fill Curve node applied to the star primitive.#
![../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_1.png](../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_1.png)
Here, a single curve point is joined to the star primitive to customize the triangulation.#
![../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_2.png](../../../../_images/modeling_geometry-nodes_curve_curve-fill_example_2.png)
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.
![](../../../../_images/modeling_geometry-nodes_curve_curve-fill_group-id_0.png)
Here, the 4 curves share the same Group ID, resulting in 1 mesh island (default behavior).#
![../../../../_images/modeling_geometry-nodes_curve_curve-fill_group-id_1.png](../../../../_images/modeling_geometry-nodes_curve_curve-fill_group-id_1.png)
Here, the 4 curves have different Group ID, resulting in 4 mesh islands.#
![../../../../_images/modeling_geometry-nodes_curve_curve-fill_group-id_2.png](../../../../_images/modeling_geometry-nodes_curve_curve-fill_group-id_2.png)
Here, the 4 curves are seperated into two groups based on their positions, resulting in 2 mesh islands.#
