I have reproduced the bug. It seem to be a bug in swig: it doesn't
recognize itk::DefaultDynamicMeshTraits<double,2,2,double> and
itk::DefaultDynamicMeshTraits<double,2,2,double,float,double> as the same
entity in the typemap, but recognize it as it should elsewhere.
A simple workaround is to wrap the itk::Mesh class in your project with
the full template parameter list:
#
# Define the mesh types
#
WRAP_TYPE("itk::Mesh" "M")
FOREACH(d ${WRAP_ITK_DIMS})
WRAP_TEMPLATE("${ITKM_D}${d}S"
"${ITKT_D},${d},itk::DefaultStaticMeshTraits<
${ITKT_D},${d},${d},${ITKT_D},${ITKT_F},${ITKT_D} >")
WRAP_TEMPLATE("${ITKM_D}${d}D"
"${ITKT_D},${d},itk::DefaultDynamicMeshTraits<
${ITKT_D},${d},${d},${ITKT_D},${ITKT_F},${ITKT_D} >")
ENDFOREACH(d)
END_WRAP_TYPE()
SET(itk_Wrap_Mesh ${WRAPPER_TEMPLATES})
WRAP_CLASS("itk::Mesh" POINTER)
SET(WRAPPER_TEMPLATES ${itk_Wrap_Mesh})
END_WRAP_CLASS()
It will give you some warning, but it works.
Please file a bug report on kitware's bugtracker, so we won't forgot to
fix that.
Luis, can you add me a bug tracker account, so the bug can be assigned to
me ?
Thanks,
Gaetan
