<br>Hi Josu,<br><br>Thanks for trying the MeshToMesh registration framework<br>and for reporting back.<br><br>Please note that this framework is intended to register the<br>scalar fields associated with the nodes of two spherical meshes.<br>
<br>It is not intended to perform a point-based registration<br>(such as ICP (iterative closest point) ). <br><br>Therefore , it is expected that the meshes that you provide<br>as input will have the following three characteristics:<br>
<br> A) The points are placed in the surface of a sphere<br><br> B) PointData (PixelType) associated to every point <br> in the mesh is a scalar value.<br><br> C) The topology of the mesh is such that it represents<br>
a discretization of 2D manifold embedded in a 3D<br> space. (e.g. the typical case of a 2D surface surrounding<br> a 3D object.<br><br><br>Please note also that the code must be build against a <br>
CVS version of ITK. Since many of the classes depend<br>on code that is in the Insight/Code/Review directory.<br><br>Try updating your CVS checkout of ITK, then recompiling<br>the Mesh to Mesh registration code, and let us know if<br>
you still find any problem.<br><br><br> Regards,<br><br><br> Luis<br><br><br>------------------------------<br><div class="gmail_quote">On Tue, Jun 23, 2009 at 11:15 PM, Josu Maiora <span dir="ltr"><<a href="mailto:jmaiora@gmail.com">jmaiora@gmail.com</a>></span> wrote:<br>
