Hi every one..!
i am new user of paraview,actually i am simulating a mixer that contain two different glass particles in LIGGGHTS ,one has dai 2mm and second has dia of 3mm.My problem is when i open the simulations files form LIGGGHTS in paraview it shows particles in points form with same size and with spacing as well. i want to see particles with original size and with no space in between them.
I got the idea of "PointSprite plug-in" in ParaView from some where.I made changes like this
{ In Object Inspector - Display" select "Scale by - radius", then push the button "Edit Radius Transfer Function" and finally select "Proportionnal" instead "Use scalar range".}
but the problem is that when once i select the files from LIGGGHTS and push the apply button and then i make these changes then the apply button is not available to apply again ,i mean i can't apply the setting of PointSprite plug-in.
So please any body who know about this ,kindly guide me .I am suffering for last two months due to this problem.
I also used the idea of Glyph in this way
In Glyph properties:

Scalars radius
Glyph type Sphere
Radius 1
Scale Mode Scalar
Set Scale Factor 1
now i don't know what to write in "Max # of points box" ????

Is this is the total number of particles ??
when i considered this as total # of particles ,so in my case there are 50000 particles ,when i put 40000 or 50000 in given box its stop works.
please need help in this regards too.
Thanks
