填充曲线

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

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

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

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

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.

填充曲线 - 图5

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

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

../../../../_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.
