Fill Curve Node

Fill Curve node.

The Fill Curve node generates a mesh using the constrained Delaunay triangulation algorithm with the curves as boundaries. The mesh is only generated flat with a local Z of 0.

Inputs

Curve

Standard geometry input with a curve component.

Group ID

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

Properties

Mode

The type of geometry the output consists of.

  • Triangles:

    The output is made up of triangles.

    N-gons:

    The output is made up of n-gons.

Outputs

Mesh

The filled-in curves.

Examples

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.

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

Group ID

The following figures display diverse application of the Group ID.

Fill Curve Node - 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.
