[Paraview] Uniform rectilinear grid LOD

[antoine vial]

Hi,

I'm importing seismic files into paraview as .vti (Image file)  to display
them as a volume but I can't get a "nice" display (impossible to
distinguish a layer from one to another). It seems that every cell is
interpolated with all its neighbors and therefore it creates some sort of
"stains" much bigger than the original cell size. However, when I'm turning
the representation mode into surface, the display looks exactly as it
should: cells are not interpolated whit each other and therefore I can
distinguish my layers.

I'm not sure if I made myself clear enough so I enclosed two pictures.

This one represent the volume display where you can clearly see the problem

this one is the surface display over the same area and you can see the
actual cell size

So I would like to know if someone have a hint about how to deactivate the
interpolation. As I started recently with paraview, it might be that my
problem comes from somewhere else but I'm pretty sure that my script to
convert seismic file to vtk is correct.

Thanks for reading
Cheers
Antoine
