|
||
|
|
* @brief deform geometry with scalar data
|
||
|
|
*
|
||
|
|
* 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.
