[vtkusers] The VTK Journal-New Submission

[Alexandre GOUAILLARD]

hi david,

obj, as vrml is supposed to handle complete scenes. That explain the
original difference between Reader/Writer of objects and
Importer/Exporter of scenes.

I know that obj is often used to store mesh objects only, but was it
really necessary to add a class that somehow duplicate existing
feature? I say that naively without having read your paper first, feel
free to throw a stone at me :-)

Basically you would have this:
polydata => objwriter

instead of that:
polydata => mapper => actor => renderer => renderWindows => OBJexporter

and it would only be interesting in the case where you only have a
single polydata, and/or when you have a polydata processing pipeline
that would not otherwise require a graphic pipeline,

correct?

alex.
