[Paraview] visualizing a material in paraview

2012-07-20 Thread Celia Bremer


Hello,

I'm new to Paraview. I have 2 questions about visualizing an atomic material 
from a LAMMPS simulation.

1. I got the atom coordinates in from LAMMPS into Paraview using Pizza.py. When 
I just import the file, I can look at it as-is using point representation. To 
make it look more like atoms, I can also use the glyphs filter on the input 
file. But! some of the points end up outside the spheres. My question is, why 
are there points that don't turn into spheres? How does PV decide what turns 
into a glyph and what doesn't?

2. What I'd like to do next is to see the pore space - i.e., everything that's 
in my simulation box that's outside the glyphs. Is there already a filter for 
that? I thought I might be able to make a box that's the same size as my 
simulation box and intersect it with the glyphs object, but I can't figure out 
how to do that.

Thank you!

1) Look at the bottom of the glyph filter's properties tab. Max number
of points and random mode says pick 5000 points at random and only
glyph those. If turning that off makes paraview slow consider the
point sprite or manta plugins.

2) Use the gaussian resampling filter to push the values onto a
regular grid and then isocontour that.
