I have a nice long file, in the format:

-1.000000E+01 -1.000000E+01 -1.000000E+01 1 1 0
-1.000000E+01 -1.000000E+01 -9.000000E+00 1 1 0
-1.000000E+01 -1.000000E+01 -8.000000E+00 1 1 0
-1.000000E+01 -1.000000E+01 -7.000000E+00 1 1 0
-1.000000E+01 -1.000000E+01 -6.000000E+00 0 1 -1
-1.000000E+01 -1.000000E+01 -5.000000E+00 0 1 -1
-1.000000E+01 -1.000000E+01 -4.000000E+00 0 1 -1


The first three columns are x, y, and z coordinates. The next three are 
data associated with the coordinates (to be represented as colour, size, 
etc..)

I haven't had much luck loading these into PovRay. Pov seems to want 
comma separated numbers, but this isn't feasable. I tried loading the 
numbers in one at a time with:

#read (datafile,buffer)

Then output them with:

#debug str(buffer,0,1)

but it seems to loose negative signs and get generally confused.

Any suggestions?

  Why not?

  If you want to add the commas, you can use any editor with
search&replace and replace the whitespaces with commas.

  -something -something -something is a substraction and POV-Ray probably
reads it as such.
