Rotational Extrusion (RotationalExtrusionFilter)
This filter generates a swept surface while translating the input along a circular path.
The Rotational Extrusion filter forms a surface by rotating the input about the Z axis. This filter is intended to operate on 2D polygonal data. It produces polygonal output.

PropertyDescriptionDefault Value(s)Restrictions
Angle
(Angle)
This property specifies the angle of rotation in degrees. The surface is swept from 0 to the value of this property. 360  
Capping
(Capping)
If this property is set to 1, the open ends of the swept surface will be capped with a copy of the input dataset. This works property if the input is a 2D surface composed of filled polygons. If the input dataset is a closed solid (e.g., a sphere), then either two copies of the dataset will be drawn or no surface will be drawn. No surface is drawn if either this property is set to 0 or if the two surfaces would occupy exactly the same 3D space (i.e., the Angle property's value is a multiple of 360, and the values of the Translation and DeltaRadius properties are 0). 1

Only the values 0 and 1 are accepted.

 
Delta Radius
(DeltaRadius)
The value of this property specifies the change in radius during the sweep process. 0  
Input
(Input)
This property specifies the input to the Rotational Extrusion filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkPolyData.

 
Resolution
(Resolution)
The value of this property controls the number of intermediate node points used in performing the sweep (rotating from 0 degrees to the value specified by the Angle property. 12

The value must be greater than or equal to 1.

 
Translation
(Translation)
The value of this property specifies the total amount of translation along the Z axis during the sweep process. Specifying a non-zero value for this property allows you to create a corkscrew (value of DeltaRadius > 0) or spring effect. 0
