vtkWarpScalar is a filter that modifies point coordinates by moving points along point normals by the scalar amount times the scale factor. Useful for creating carpet or x-y-z plots.
If normals are not present in data, the Normal instance variable will be used as the direction along which to warp the geometry. If normals are present but you would like to use the Normal instance variable, set the UseNormal boolean to true.
If XYPlane boolean is set true, then the z-value is considered to be a scalar value (still scaled by scale factor), and the displacement is along the z-axis. If scalars are also present, these are copied through and can be used to color the surface.
Note that the filter passes both its point data and cell data to its output, except for normals, since these are distorted by the warping.

Instantiate object with no start, end, or progress methods.

|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkSource. |

Turn on/off use of user specified normal. If on, data normals will be ignored and instance variable Normal will be used instead. |

Turn on/off flag specifying that input data is x-y plane. If x-y plane, then the z value is used to warp the surface in the z-axis direction (times the scale factor) and scalars are used to color the surface. |
