Hi =)<br>
<br>
<br>
<br>
I´ve got a question about vtkTriangleFilter<br>
<br>
<br>
I want to insert a vtkAppenPolyData into a vtkTriangleFilter like this.<br>
<br>
<br>
                        Packungscontainer1[u] = vtkAppendPolyData::New();<br>
                        Packungscontainer1[u]-&gt;AddInput(Packungscontainer[i]-&gt;GetOutput());<br>
                        Packungscontainer1[u]-&gt;Update();<br>
<br>
                        vtkTriangleFilter *PackungsModell = vtkTriangleFilter::New();<br>
                        TrunkModell-&gt;SetInput(Packungscontainer1[u]-&gt;GetOutput());<br>
                        TrunkModell-&gt;GetOutput()-&gt;ReleaseDataFlagOn();<br>
                        PackungsModell-&gt;Update();<br>
<br>
But when i run my program, an error occurs:<br>
<br>
ERROR: In ..\..\vtk-5.6.0\Filtering\vtkDemandDrivenPipeline.cxx, line 728<br>
vtkStreamingDemandDrivenPipeline (02D56630): Input port 0 of algorithm<br>
vtkTriangleFilter(02ABAF28) has 0 connections but is not optional.<br>
<br>
<br>
<br>
can someone explain why this error occurs, btw. what i did wrong?<br>
<br>
Best Regards, René<br>
<br>
