[vtkusers] vtkWarpScalar Simple Problem but please help.

[Richard.Bridge at tessella.com]

Hi,

I am trying to do a simple carpet/Surface  plot but I have been having 
lots of trouble. I basically have x, y and z data  and I just want to warp 
the x-y plane by the z. I have tried about 10 different ways to do this, 
including the contour filter, but without success. I think my main problem 
is in creating the original vtkData object (in java)?

At the moment I am creating a rectilineargrid with z = 0 and extracting 
the z plane as polyData, then setting my scalar values (a vtkFloatArray), 
see code below.

Please help, I am tearing my hair out on this one!

Richard


//Set the scalars to the points
        vtkPolyData vol = geoFilter.GetOutput();
 
        vol.GetPointData().SetScalars(scalars);
 
        vtkWarpScalar warp = new vtkWarpScalar();
        warp.SetInput(vol);
        warp.UseNormalOn();
        warp.XYPlaneOff();
        //warp.SetScaleFactor(0.5);
 
        vtkPolyDataMapper mapper = new vtkPolyDataMapper();
            mapper.SetInput(warp.GetPolyDataOutput());//test
            //mapper.ScalarVisibilityOff();
 
 
 
        vtkActor surfaceActor = new vtkActor();
            surfaceActor.SetMapper(mapper);
            surfaceActor.GetProperty().SetColor( 0.4,0.2, 0.1);
