Hello,
I am trying to make a C++ reader for a point set file containing time steps.
The output of the reader is a vtkPolyData.
The file format is similar to:
x1,y1,z1,prop1,prop2,...,time
I would like to import the field "time" as time steps, in order to animate
using "snap to time steps" mode.
The code looks like:
vtkPolyData *output =
vtkPolyData::SafeDownCast(outInfo->Get(vtkDataObject::DATA_OBJECT()));
Loop:
time = readTime();
coords = readCoords();
vtkIdType id = outPoints->InsertNextPoint(coords[0], coords[1],
coords[2]);
outCells->InsertNextCell(1);
outCells->InsertCellPoint(id);
output->SetPoints(outPoints);
output->SetVerts(outCells);
Assuming time is an integer, how do I insert the time steps into the output
?
I tried to import the time as an "int property" instead of time steps and
animate using threshold, but I can't display one time step at a time
because only one slider is animated. I tried a threshold on a threshold to
animate 2 sliders but couldn't get the exact effect that "snap to time
steps" would give if I had time steps.
Thank you,
Nehme
