Objet : Rép : [Paraview] plotting only the viewable part of a very
large
Streaming and AdaptiveParaView do that like so:
reader supplies meta information including piece bounding boxes
a filter, vtkVisibilityPrioritizer, is inserted at the end of the
pipeline
vtkVisibiltyPrioritizer gets the camera/viewport and the bounding
boxes (if they are not transformed by the intermediate filters) and
rejects pieces that are offscreen so that they are never
read/processed at all
AdaptiveParaView goes one step further and progressively increases the
sampling resolution of each piece
some very recent work by Jon Woodring @ LANL goes further and uses the
screen resolution to improve the resolution sampling algorithm and
works with unstructured data of a particular format
Feel free to try/extend and or borrow from those two experimental
ParaView applications.

Hi everybody,
I have a very large dataset (structuregrid). (1E4 X 1E4 X 1E4 X 3 )
I will like to know if is possible for the reader (home made
reader) to know
the resolution of the screen and the volume of space that the
camera is
looking at.
I will like to generate de data only for the viewable portion of
the space
(at the right resolution).
The idea is to have something like "google hearth".
