Merge by Distance Node

The Merge by Distance node merges selected mesh vertices or point cloud points within a given distance, merging surrounding geometry where necessary. This operation is similar to the Merge by Distance operator or the Weld Modifier.

Inputs

Geometry: Standard geometry input.
Selection: Boolean field that is true for parts of the geometry to be deleted. Unselected points will be completely unsed for the operation-- they will not be merged into other points, and no points will merge into them either.

نصيحة

When possible, using the selection input can be a simple way to speed up the node, since searching for nearby points is a relatively expensive operation that gets even more expensive when more points are involved.
Distance: The distance to use for searching for nearby points.

Properties

Mode

Method for choosing which vertices are merged.

All: Merge includes all geometry including loose parts.
Connected: Merge only includes attached geometry i.e. the modifier will not merge loose parts together.

Output

Geometry: Standard geometry output.
