<div dir="ltr"><div><div><div>Hello all,<br><br></div>Has anyone used Paraview to visualize Deformable Registration Displacement fields in Paraview? I am having trouble verifying what exactly paraview is showing me. A point (x,y,z) where I know a large y-deformation occurs does not exhibit that vector magnitude in Paraview, but it DOES seem to exist at a spatial coordinate that corresponds to where the large deformation ENDS (ie where the (x,y,z) point is located AFTER registration).<br>
<br></div>Between this, and 'flipping' the x- and y- components of the vectors in the displacement field, I have managed to become very confused about the proper way to visualize the data.<br><br></div><div>Note that after using WarpImageFilter with my registration-produced displacement field, I get the registered output I was looking for (yay!). It's just visualizing the proper deformation field for visual/qualitative figures is completely eluding me.<br>
</div><div><br></div>Any help is greatly appreciated, though I feel like my emails in this user-list not up to par in terms of how I describe my problem, or the information I pass along is not enough to have an experienced ITKer chime in. If this is the case, please tell me what other info you need,as I'm happy to provide it.<br clear="all">
<div><div><div><div><br></div><div>Alternatively, if it's best I address this to a Paraview-users community, I can try that. I just figured anyone who used Demons in ITK would most likely also visualize the field..<br>
