I've written a VTK File Reader that supports multiple timesteps (48 in my
tests). But when I load the data, it shows me no timestep data in the
properties panel, and the time increment thing at the top toolbar is greyed
out. However, if I use the Animation tools to animate from timestep0 to 47
in 48 steps, it properly animates through time.
What am I doing wrong? My RequestInformation (where I think this
information comes from) is shown below:
//----------------------------------------------------------------------------
int vtkAdhfaNetwork::RequestInformation(
vtkInformation* reqInfo,
vtkInformationVector** inVector,
vtkInformationVector* outVector
)
{
if(!this->Superclass::RequestInformation(reqInfo,inVector,outVector))
{
return 0;
}
vtkInformation *info=outVector->GetInformationObject(0);
double tRange[2];
tRange[0] = this->Steps[0];
tRange[1] = this->Steps[this->NumSteps-1];
info->Set(
vtkStreamingDemandDrivenPipeline::TIME_RANGE(),
tRange,
2);
info->Set(
vtkStreamingDemandDrivenPipeline::TIME_STEPS(),
this->Steps,
this->NumSteps);
return 1;
}
