Inputs
Here you can input the geometry to the Node to which the Edge Loops should be adapted.
The function can be limited to one selection, which you can connect here. Otherwise an existing active selection of the selected type can be applied to the geometry. Note when using a polygon selection that only the contours of this selection can be modified.
Here you select the type of selection used. You can choose from Points, Edges or Polygons. In Polygon mode, only the edge contour of the selection will be smoothed.
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.
The selected elements are smoothed by interpolating neighboring points. When smoothing Edge Loops, the original distance between points along the loop will also be taken into consideration. Increasing the number of iterations can strengthen the smoothing effect.
The edges passing through the selected points or the outer boundary of a polygon selection are output as a selection.
