Rigid Similarity Transformation Algorithm

[jeffryhartanto]

Hi, I want to apply the Similarity Transformation Algorithm with CGAL, but I found the closest rigid registration library is OpenGR which uses Super4PCS. Is there any way for me to achieve what I want using this library?

I have tried providing 4 source points and normals to match the 4 target points and normals. But, the returned transformation matrix has the translation part correct with identity in the rotation part, which is not expected. Thus, the source model was just translated to the target model without any rotation.
