[Insight-users] How to map a 3DMesh vertex to a specific pixel on a DICOM image?

[Luis Ibanez]

Hi Marcus,

If what you want is to find the pixel index corresponding
to every vertex in your Mesh, you can simply use the method
provided by the image class:

      image->TransformPhysicalPointToIndex(  vertex, index );

This method takes the physical coordinates of your vertices
and return the image index that you can use to address the
image pixels, for example for calling

      PixelValue = image->GetPixel( index );


   Regards,


      Luis
