[Insight-users] How to do an affine transform on one 3D point set in ITK?

[Andreas Schuh]

Hi Tao,

there might be a way to do this with ITK. However, from the kind of  
your data, the VTK might be better suited. The data you describe is  
represented in VTK as vtkUnstructuredGrid, where the cells are 0D  
(i.e. points). This data can be transformed using the  
vtkTransformFilter.

Whether you may want to use the VTK instead of ITK is dependent on  
your further purpose.
