Personaly, I prefered to add +fn in the povray.ini file before going to
If at all possible, use the animation feature. That way, you can render
many frames with only one command. Use the #fopen #fread commands to
read your data, or beter, use #include "FileName" (you can include files
that have any extention as long as they contain valid SDL code), and use
string operation to construct the required files names if you need
different data set per frame.
If your legacy code DON'T support animation, then it's pre version 3.0...
