Inputs
Here you direct the geometry to the Node whose point positions and normal directions you want to query e.g., point positions, Normal directions or other point related information like weightings, colors or point selections. Spline geometry is not supported.
If you want to limit the evaluation of the Node only to certain points, you can connect a point selection here.
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.
These options are only relevant if you have restricted the evaluation of the geometry by defineing a Selection or Selection String. In this case, the edges and polygons at which at least one point was selected by the selections are optionally output as well. Otherwise, only the edges and polygons where all the points involved in them are selected are taken into account.
Use this menu to set the calculation type of the point standards. So it is about how the normals of the surrounding polygons are evaluated. You can select from:
- Angle-weighted: The Normals of polygons that have a greater angle to the area under consideration are given more weight than the Normals of flatter-angled polygons.
- Area weighted: The Normals of the larger polygons contribute more to the calculation than the Normals of smaller areas.
- Uniform: Here a simple average calculation of the adjacent normal directions takes place.
If you have saved color information, including its alpha portion to the geometry, and want to output it to the Node, enter the name under which these colors were saved here.
If weightings have been saved on the geometry and you want to output them on the Node, enter the name under which the weightings have been saved here.
