Inputs
Here you pass the geometry to be processed to the Node.
If you want to use a selection to limit the search for N-gons on the geometry, you can choose here from Points, Edges or Polygons mode. Provided there is an active selection of the corresponding type on the geometry, only the N-gons that contain at least one selected element will be converted.
Alternatively, you can route a Selection directly to the Node via index operation. If no selection is linked and there is no selection on the geometry, the entire geometry will automatically be searched for N-gons.
If you want to limit the search for N-gons to a specific area of geometry, you can pass the index numbers of the points, edges or polygons to be searched to the Node here. Select the appropriate element type in the Type menu. Alternatively, the Node will fall back to an active selection of the geometry if you leave the Selection port unused.
Here you can, for example, use the name of a selection in quotation marks that you want to read out, e.g., "MySelection". Otherwise, the default entry will use an active selection on the geometry.
You can also use special keywords and logical operations here to create a new selection from scratch or a combination of already saved selections. The following keywords and operations can be used:
- Default: This term causes an active selection currently present on the geometry to be used. If no selection is active, all points will be used.
- odd: This term is used to select all elements that have an odd index number.
- even: This term is used to select all elements that have an even index number.
- all: This selects all elements of the selected type.
- hidden: Selects the hidden elements of the geometry.
- Name of a saved selection: If you enter the name of a saved selection in quotation marks, this selection will be read and used. To use a combination of a saved selection and another keyword or selection, use quotation marks with the selection name.
- Index numbers: You can also use index numbers directly, just as you are used to from the Index Array From String Node.
- Mathematical and logical operations: Mathematical or logical operations can be used to combine selections. Using the string odd – "center" for instance selects all odd elements and then subtracts the selection that has been stored by the name "center". You can use +, -, & (logical and), | (logical or) as well as a comma to combine multiple selections or index sequences.
