[Insight-users] Problems compiling code using itkDeformableSimplexMesh3DFilter

[T. Boettger]

Hi Michael,

there is a test for this class in:
   
    InsightToolkit-2.0.0\Testing\Code\Algorithms

 From the tests source code you can learn how to define the correct 
types for the simplex mesh classes. The compile error is produced 
because you do not specify a MeshTraits object which stores the data 
type for the points of the mesh. If you follow the test it should work.

You could also take a look at the insight applications directory. There 
is a small application (with the name DeformableSimplexMeshes or 
something like this) showing the use of the simplex mesh deformation 
algorithm.


  Best,

    Thomas
