Hi

Put your vtkPoints into a dataset like vtkPolyData and write that to disk...

vtkPoints points
    points InsertPoint 0 1 2 3
vtkPolyData data
    data SetPoints points

vtkPolyDataWriter writer
    writer SetInput data
    writer SetFileName c:/points.vtk
    writer Write

Hi, I am trying to write the points into a file. i have tried some methods
but they don't work for me.
should I transform the vtkpoints to some other formats?

the purpose for writing into a file is doing point-based registration, how
can i do that?

thanks alot
