Method InterpolateEdge

Filters/General/vtkBoxClipDataSet.cxx:661–676

------------------------------------------------------------------------------ InterpolateEdge: Interpolate the data in a vtkDataSetAttributes along a line This method works very much like vtkDataSetAttributes::InterpolateEdge except that rather than take the interpolation information from an input and copy it to an output, the values to interpolate are already placed in the output arrays. This

// will continually cut (and consequently interpolate) the input until it
// fits within the bounds.
void vtkBoxClipDataSet::InterpolateEdge(
  vtkDataSetAttributes* attributes, vtkIdType toId, vtkIdType fromId1, vtkIdType fromId2, double t)
{
  int numArrays = attributes->GetNumberOfArrays();
  for (int i = 0; i < numArrays; i++)
  {
    vtkAbstractArray* array = attributes->GetAbstractArray(i);

    // We are ignoring any special interpolate flags (such as nearest neighbor
    // interpolation).  That kind of interpolation is not linear and could be
    // incorrect when multiple cuts are performed on the same primitive (which
    // can happen).

    array->InterpolateTuple(toId, fromId1, array, fromId2, array, t);
  }
}
