Inputs
Here you can connect the geometry to be checked and repaired, if necessary.
If you have an active selection on the geometry or if you want to assign a selection via the separate Selection input, select the type of selection here. You can choose from points, edges or polygons. If you do not have an active selection and do not pass a selection to the Node, all geometry will automatically be checked.
If there is no active selection on the geometry or you want to have another area on the geometry checked, you can direct the indices of the points, edges or polygons to the Node to be repaired here, if necessary. Pay attention to the corresponding setting in the Type menu.
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.
Since detaching the polygons at the multiple-used edges detaches neighboring surfaces, there may also be a change to the Phong smoothing of the shading on the surface. Activating this option causes the surface Normals to be realigned and the shading to be updated.
