I am using a vtkTemporalStreamTracer in combination with a (self constructed) vtkTemporalDataSet. My code looks something like this:<div><br></div><div><div>vtkSmartPointer<vtkTemporalDataSet> temporalVectors = vtkSmartPointer<vtkTemporalDataSet>::New();</div>
<div>temporalVectors->SetNumberOfTimeSteps(NUM_ANIMATION_FRAMES);</div><div>for(int i = 0; i < NUM_ANIMATION_FRAMES; ++i)</div><div>{</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>temporalVectors->SetTimeStep(i, readerVector[i]->GetOutput());</div>
<div>}</div><div>temporalStreamTracer = vtkSmartPointer<vtkTemporalStreamTracer>::New();</div><div>temporalStreamTracer->SetInput(temporalVectors);</div><div>temporalStreamTracer->SetTimeStep(2);</div></div><div>
temporalStreamTracer->SetSource(sourceData);</div><div><br></div><div>I think add a standard mapper/actor to show the results on the screen. However, I get no output at all. The polydata output of the temporalStreamTracer seems to be emtpy. If I replace the temporal streamtracer by a vtkStreamTracer and use readerVector[0] as the input, everything works as expected. Is there something that I'm missing to get the temporal streamtracer to work?</div>
