[Paraview] Highlighting specific nodes as a function of time

[Pradeep Jha]

I think I can state my question much more simply. I have a file with data
like this:

 00000,       241,          54,         310
 00006,       241,          54,         308
 00012,       240,          55,         310
 00018,       239,          55,         310
 00024,      261,         294,         395
:::::::::::::::::::::::::::::::::::::::::::::::::::
:::::::::::::::::::::::::::::::::::::::::::::::::::
 00030,       256,         373,          32
 00036,       257,         372,          32
 00042,       257,         371,          32
 00048,       258,         370,          32
 00054,      258,         369,           32

The first coloumn is the time stamp and the following three coloums are the
x, y and z coordinates. I want to highlight the points in the file as
function of time in a cube of 512x512x512 such that the only the particular
node has a sphere (for example) and the rest of the domain is empty.

How can I do that?
