Detailed Description
Contour interpolator for DEM data.
vtkTerrainContourLineInterpolator interpolates nodes on height field data. The class is meant to be used in conjunciton with a vtkContourWidget, enabling you to draw paths on terrain data. The class internally uses a vtkProjectedTerrainPath. Users can set kind of interpolation desired between two node points by setting the modes of the this filter. For instance:
contourRepresentation->SetLineInterpolator(interpolator);
interpolator->SetImageData( demDataFile );
interpolator->GetProjector()->SetProjectionModeToHug();
interpolator->SetHeightOffset(25.0);
You are required to set the ImageData to this class as the height-field image.

Interpolate to create lines between contour nodes idx1 and idx2.
Depending on the projection mode, the interpolated line may either hug the terrain, just connect the two points with a straight line or a non-occluded interpolation. Used internally by vtkContourRepresentation.
Implements vtkContourLineInterpolator.
|
virtual |
The interpolator is given a chance to update the node.
Used internally by vtkContourRepresentation Returns 0 if the node (world position) is unchanged.
Reimplemented from vtkContourLineInterpolator.
|
virtual |
Set the height field data.
The height field data is a 2D image. The scalars in the image represent the height field. This must be set.

Get the vtkProjectedTerrainPath operator used to project the terrain onto the data.
This operator has several modes, See the documentation of vtkProjectedTerrainPath. The default mode is to hug the terrain data at 0 height offset.
