<font size="-1">Hello all,<br>
I created a pipeline that seems to make sense to me, but always my
polyDataComplete is empty. Any ideas why this code doesn't work?
The only vtkPointToCellData example on the web that I can find
uses blow.vtk, which doesn't exist on my 6.0.0 installation
anywhere. The polyData variable gets correctly populated with the
points and their scalars below.<br>
<br>
// Create a new, empty polyData<br>
polyData = new vtkPolyData();<br>
<br>
// populate the polyData points<br>
polyData.SetPoints(points);<br>
<br>
// populate the polyData scalars<br>
polyData.GetPointData().SetScalars(colorsScalars);<br>
<br>
vtkPointDataToCellData polyDataCreateCells = new
vtkPointDataToCellData();<br>
polyDataCreateCells.SetInputData(polyData);<br>
polyDataCreateCells.PassPointDataOn();<br>
<br>
// Create new polyData, retrieve completed polyData from
polyDataCreateCells<br>
vtkPolyData polyDataComplete = new vtkPolyData();<br>
polyDataComplete =
polyDataCreateCells.GetPolyDataOutput();<br>
<br>
vtkPolyDataMapper polyMapper = new vtkPolyDataMapper();<br>
polyMapper.SetInputData(polyDataComplete);<br>
polyMapper.ScalarVisibilityOn();<br>
polyMapper.SetScalarRange(scalarMin, scalarMax);<br>
polyMapper.Update();<br>
<br>
vtkActor polyActor = new vtkActor();<br>
polyActor.SetMapper(polyMapper);<br>
polyActor.GetProperty().SetColor(1.0, 1.0, 1.0);<br>
<br>
// ...Usual render stuff...<br>
<br>
Thanks,<br>
