Using Displacement Map to Deform or Morph a Segment/Model

Support

@lassoan,

I found this post and I am trying to repeat the process;

First, I ran Model To Model Distance and created D_rev2orig as the “displacement model”
Additionally, I have a “target” model D_ST which I would like to warp/deform.

Here is what I am doing to warp the “target” model;

dispModel = getNode("D_rev2orig")
targetModel = getNode("D_ST")

dispMesh = dispModel.GetMesh()
dispMesh.GetPointData().SetActiveVectors("PointToPointVector")

warp = vtk.vtkWarpVector()
warp.SetInputData(dispMesh)

warp.SetScaleFactor(1.0)
warp.Update()
targetModel.SetPolyDataConnection(warp.GetOutputPort())

This overrides the D_ST “target” model and generates a weird hybrid model;

This model has the PointToPointVector attribute from the displacement model D_rev2orig, but does not have the geometry of the “target” model. The geometry is not the same as the “displacement model” however, so maybe I am just missing something in the script above?
