[Python-apps-team] Bug#479448: mayavi2: please implement vector component extraction

[Francesco Poli]

Package: mayavi2
Version: 2.1.1-2
Severity: wishlist

Hi!

I am unable to find a way to use a vector component as scalar.
E.g.: suppose I want to visualize the x-component of the velocity
vector (computed from data read from a PLOT3D file, or directly
read from VTK file) as a color scalar...  how can I do that?

In MayaVi1 there's the ExtractVectorComponents filter; I fail
to find anything similar in MayaVi2.

Could this be implemented, please?
Please forward this bug report to upstream, thanks.
