    Hi all,<br>
    <br>
    I'm currently trying to extract smooth meshes from binary masks. In
    summary, I use&nbsp; "itk:: BinaryMask3DMeshSource " followed by a
    itk::AntiAliasBinaryImageFilter and use "vtkPolyDataReader" and
    "vtlPolyDataWriter" to handle the generated masks and its dumps.&nbsp;
    Everything seems its just that since I have large segmented volume
    at real fine resolution I get a lot of vertices and faces for the
    Triangular mesh that gets generated. I wanted to decimate the number
    of triangles. Found Online it could done using itk::QuadEdgeMesh.
    Copied and Modified the code appropriately. The code compiles just
    fine but I get linker errors. Now, I'm not a expert and would
    appreciate how I get rid of these. I'm unable to find which lib
    would need to be linked for this (but I'm not even sure if this is
    the solution path) ?<br>

    Here is the part of the BUILD dump: <br>
