[Paraview] Distance visualisation

[dave.demarle at kitware.com]

Assuming the topology is the same and a 1:1 correspondance between the two, it would be very easy to do with the python programmable filter.

Script would:
get hold of both input data sets
copy either to the output data set
make a new point associated double array and add it to the output
make the array 3 components wide
iterate over points
  store del x,y,z in output array

See the paraview wiki for examples that get0you 90% of the way there.

Ok it is lets say the "normal distance" between the elements. These two meshes represents two geometries which are very simular and I simply want to visualise where and how much the geometries differ....

Regards.




How do you define distance?
