[Insight-users] Help with using itk::QuadEdgeMesh

[Vimal Singh]

Hi all,

I'm currently trying to extract smooth meshes from binary masks. In 
summary, I use  "itk:: BinaryMask3DMeshSource " followed by a 
itk::AntiAliasBinaryImageFilter and use "vtkPolyDataReader" and 
"vtlPolyDataWriter" to handle the generated masks and its dumps.  
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) ?

Here is the part of the BUILD dump:

convertMaskToSmoothMesh.obj : error LNK2019: unresolved external symbol
