Hi Karthik,<br><br>thanks for pointing that out, I missed the<br>second (original) implementation. However,<br>even if I change vtkImageActorPointPlacer as<br>suggested, this will not work, at least with<br>MS Vis Studio, since the signatures of the
<br>vtkBoundedPointPlacer's ComputeWorldPosition<br>are equivalent due to the vtkNotUsed macro:<br><br>// first appearanc in implementation file<br>// of ComputeWorldPosition<br>int vtkBoundedPlanePointPlacer::ComputeWorldPosition(
<br> vtkRenderer * ren,<br> double displayPos[2],<br> double refWorldPos[3],<br> double worldPos[3],<br> double * vtkNotUsed(worldOrient) )<br>{<br><br><br>// second implementation "looks" the same
<br>// so the compiler always calls the first implementation<br>int vtkBoundedPlanePointPlacer::ComputeWorldPosition( vtkRenderer *ren,<br> double displayPos[2],<br> double worldPos[3],
<br> double worldOrient[9] )<br><br><br>I tried and the contour widget's handle translation still does<br>not function.<br><br>Dean<br><br><br>><br>> Hi Dean,
<br>><br>> Could you please check if the following change to vtkImageActorPointPlacer<br>> fixes it.<br>><br>> On line 78, replace<br>> this->Placer->ComputeWorldPosition( ren, displayPos, refWorldPos,
<br>> worldPos, worldOrient );<br>> with<br>> this->Placer->ComputeWorldPosition( ren, displayPos, worldPos,<br>> worldOrient );<br>><br>> If so, please commit it.<br>><br>> Thanks,<br>> Regards
