NodeIcon FillHoles

Fills holes in geometry with triangles

Geometry must be manifold. If it isn’t, you can use RepairGeom node beforehand.

Inputs

input geometry

Geometry A geometry to fill holes in.

Output

geometry

Geometry Geometry with its holes filled.

Tip

If input geometry has any Polygroups, the node adds more Polygroups to the output geometry for each hole it fills. The same is true with Materials. This can be used in other nodes.

For example, you can select polygroups Hole1 and Hole3 with SelectPolygons and then restore holes they correspond to with DeletePolygons.

Parameters

Method:
Triangle Fan

builds triangle fan around first point it finds.

TFNP

Triangle Fan With Extra Point

creates new vertex in the middle of each hole and builds triangle fan around it.

TFEP

Triangle Strip

builds triangle strip from first point it finds.

TS

Tip

If input geometry was symmetric, Triangle Fan With Extra Point is guaranteed to leave it symmetric, unlike other methods.
