There isn't a preexisting filter that does this, bug you can write a new filter that does exactly that -- givens a list of coorinates and labels, internally uses mulitple instances of vtkVectorText (which is what the 3D Text is ParaView uses) and then append the polydata returned by each of the vtkVectorText instances into a single polydata to put out as the output.
Here's a simple Python script that you can use as the "Script" for a "Programmable Source" to see how such a filter could be written. # ------------------------------------------------------------------------------------------- # script for RequestData Script of the Programmable Source # ------------------------------------------------------------------------------------------- from vtk.vtkRenderingFreeType import vtkVectorText from vtk.vtkFiltersCore import vtkAppendPolyData from vtk.vtkFiltersGeneral import vtkTransformPolyDataFilter from vtk.vtkCommonTransforms import vtkTransform coords = [(0, 0, 0), (0, 10, 0)] labels = ["One", "Two"] def getText(pos, text): source = vtkVectorText() source.SetText(text) transform = vtkTransform() transform.Translate(pos) transformPD = vtkTransformPolyDataFilter() transformPD.SetTransform(transform) transformPD.SetInputConnection(source.GetOutputPort()) transformPD.Update() return transformPD.GetOutput() appender = vtkAppendPolyData() for coord, label in zip(coords, labels): pd = getText(coord, label) appender.AddInputDataObject(pd) appender.Update() output.ShallowCopy(appender.GetOutput()) ------------------------------------------------------------------------------------------- On Mon, Feb 9, 2015 at 9:58 AM, <[email protected]> wrote: > Hi, > > I am currently working on a customization of ParaView.
