[Insight-users] itk::Mesh and itk::QuadEdgeMesh converter

[Alexandre GOUAILLARD]

dear gao yi,

an itk:QuadEdgeMesh is an itk:Mesh. You can pass the pointer to the
itk:Pointset directly (sharing memory), then you can just make one
loop on the cell container (and equivalent data) to feed your itk:Mesh
with the cells. There is a little bit of magic to do as the cells
types are a little bit different but nothing fancy. Namely, in a
QEMesh cells are polygons and do not differentiate from triangles,
quads or others. In your case, if you know it s triangular, then it s
easier.

Any reason you want to change it to itk:Mesh by the way? QEMesh API is
supposedly 100% compatible with Mesh, so if there is a limitation,
please let me know.

What is your specific problem? If you re at miccai, we can take a look
at it together, otherwise I can give a hand by e-mail.

alex.
