hi ... I've got  a log file wit many numbers. I want visualize this data. I
thought it could by made as surface. I need run it as batch so i thought
povray should by good for it.(generate .pov file and rendering)  But I cant
find any sample how can I create something like surface graph. IS it
possible in povray ? I'll be very thanx for any advice, links, samples how
do it.

"Many numbers" isn't enough...what *kind* of data is it? Height values? 
How many dimensions? A list of points? 3D density information?

How do you want to represent it? A graph of the distribution of the 
numbers, a graph of the numbers by time? A height field? A 3 dimensional 
solid shape? A collection of voxels? Some kind of convex hull mesh? What 
exactly do you mean by "surface graph"?

And finally, how is this information formatted? Comma delimited float or 
integer numbers in a text file? Or just spaces between the numbers? Or 
something more complex? A binary file? And how is this information 
produced? Can you modify the output to be formatted different ways, or 
are you stuck with a specific format?

POV-Ray most likely will do what you want, but you need to give more 
information if you want help. You might be able to use POV-Script to 
read in the data using the file I/O features, or you might find it more 
efficient to output the data as a bunch of macro calls. In this case, 
you could convert it to a mesh or blob object. Or you might want to 
convert it to a 3df file, and use it as media density or an isosurface 
function.
