Surface Vectors (SurfaceVectors)
This filter constrains vectors to lie on a surface.
The Surface Vectors filter is used for 2D data sets. It constrains vectors to lie in a surface by removing components of the vectors normal to the local surface.

PropertyDescriptionDefault Value(s)Restrictions
Constraint Mode
(ConstraintMode)
This property specifies whether the vectors will be parallel or perpendicular to the surface. If the value is set to PerpendicularScale (2), then the output will contain a scalar array with the dot product of the surface normal and the vector at each point. 0

The value must be one of the following: Parallel (0), Perpendicular (1), PerpendicularScale (2).

 
Input
(Input)
This property specifies the input to the Surface Vectors filter.  

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

The dataset must contain a point array with 3 components.

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

 
Select Input Vectors
(SelectInputVectors)
This property specifies the name of the input vector array to process.  

An array of vectors is required.
