<br>
I am using vtkDiscreteMarchingCubes to generate a surface mesh from a segmented image volume, prior to applying a custom smoothing algorithm and finally rendering a new image volume.<br>
<br>
The rendering step has problems when the surface mesh is not closed, which occurs when the segmented object meets a side of the image volume. Is there some way that I can generate a closed surface from the marching cubes algorithm, or postprocess the open surface (or contours generated from it by vtkCutter) to close it?<br>
<br>
Many thanks,<br>
Andrew<br>
