Didier, The find_if thing is really becuase in older paraview versions when the UPDATE_TIME_STEP was sent, it was sometimes rounded to float/double and slightly different from the declared value of time that the reader (for example) had really generated. All it does is find the closest time value to the ones you should have (actually, not closest, but one equal to or larger) - you don't rellay need it - at some point I'll update the tutorial. Leaving it in won't hurt and will at least ensure you get something meaningful.

Do you have #include <vtkstd/algorithm> at the top of your reader? find_if is declared in this header. -Ken On 12/16/09 9:02 AM, "Didier Roissé" <didier.roi...@gmail.com<http://didier.roi...@gmail.com>> wrote: Thanks John. I try , but I have problem with this: this->ActualTimeStep = vtkstd::find_if( this->TimeStepValues.begin(), this->TimeStepValues.end(), vtkstd::bind2nd( WithinTolerance( ), requestedTimeValue )) - this->TimeStepValues.begin(); I have always this following build error : error : 'find_if' is not a member of std.

And this reader reads data which is time dependent. So in RequestInformation I set the different values for steps and the min and max value of time like this : for(int i=0;i<nbtimesteps;i++) outInfo->Append(vtkStreamingDemandDrivenPipeline::TIME_STEPS(),timeStep[i]); timeRange[0]=time_min; timeRange[1]=time_max; outInfo->Set(vtkStreamingDemandDrivenPipeline::TIME_RANGE(), timeRange, 2); nbtimsteps is the number of steps. and timeSteps[i] is the value of the time at the step i. In RequestData I write the following line to see the value of UPDATE_TIME_STEPS. if(outInfo->Has(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS())) { double step = outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS())[0]; int nSteps = outInfo->Length(vtkStreamingDemandDrivenPipeline::TIME_STEPS()); double* steps = outInfo->Get(vtkStreamingDemandDrivenPipeline::TIME_STEPS()); std::cout << "Step : "<<step<<endl; for(int i=0;i<nSteps;i++) { std::cout << "steps : "<<steps[i]<<endl; } } when I display outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS())[0] for the first time value, I expected to have my first value of my timeStep, but I have 0. And if I click on the next frame button in paraview, the next value is 0.1111111. I don't understand what I am doing wrong.
