Hi, Andreas:<br><br>Thanks! <br><br>however I can't find the TransformMeshFilter usage in the ItkSoftwareGuide.

<br>
in ITK you can use itk::Mesh to represent your data and apply the itk::TransformMeshFilter to transform the points using an itk::AffineTransform. Be aware that the transformation differs for itk::Point and itk::Vector.<br>

Hi Tao,<br>
<br>
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.<br>
<br>
Whether you may want to use the VTK instead of ITK is dependent on your further purpose.<br>
<br>

Hi, All:<br>
<br>
I have a 3D point set (not an image) to be affine transformed to another 3D point set. I tried but failed. Anybody knows how to implement this using ITK?<br>
<br>
Thank you!!<br>
<br>
Tao<br>
