Hello,<br><br>I have a polydata model and I want to retriangulate it by vtkDelauny2d. I've tried like this:<br><br>void Delaunay(void)<br>{<br> vtkDelaunay2D *newMesh = vtkDelaunay2D::New();<br> newMesh->SetSource(polyData);
<br> newMesh->Update(); <br> polyData = newMesh->GetOutput();<br> polyData->Modified();<br> iren->Render();<br>}<br><br>But the following message appears:<br><br>ERROR: In d:\Ricardo\vtk-5.0.3\Filtering\vtkDemandDrivenPipeline.cxx
, line 710<br>vtkStreamingDemandDrivenPipeline (02C269C8): Input port 0 of algorithm vtkDelaunay2D(02BD2C88) has 0 connections but is not optional.<br><br>Anyone could help me?<br><br>Thanks in Advance.<br><br>Ricardo Seco
