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.

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.
