[petsc-dev] vtk viewer

[Blaise Bourdin]

Hi,

Imtiaz Hossain from the LSU visualization center and I would be interested in reimplementing the vtk viewer (at least for da and Vec obtained from a da) using libvtk. As far as I can see, the current implementation only does legacy text format which is not really amenable to large 3d models and does not support reading from a vtk file.

Would you welcome a reimplementation of the vtk viewer (I know that it means adding another dependency / library, but this could easily be made optional, just like the hdf5 reader / writer)
Is there any documentation on adding a viewer format? For what I can see, the load is implemented in src/vec/vec/utils/vecio.c and the writers are within each vector implementation. It looks like the hdf5 reader and writers were reimplemented recently, so we would probably try to follow their structure as closely as possible.

Regards,
Blaise
