  Maximum amount of variables passed through command line (Message 1 to 4 of 4)

I have a very urgent question. I want to know the maximum amount of
variables I can passed through the command line e.g shapes.pov +w100 +h100
#declare=posx=10 #declare=posY=100. Like posx and posy, how many such
variable declarations can I put in the command line?.Is there a limit or is
it unlimited?

Suppose, there was no restriction, what will be the side effect of pushing
very large amount of variables through the command line, in terms of
processing speed and quality?

I have a second question. I made some models in Moray with very smooth
curves using bezier. But when I exported the model to Povray, the curves
get distorted to such an extent that it was impossible to use it. Is there
any remedy to this?

Thanks in advance

AFAIK, it's unlimited; however, it's a lot easier to put everything into a 
.ini file - there's less chance of mastikes and orrers that way :-)

None whatsoever. The command line is processed before evrything else happens 
(if you see what I mean) and no back-reference is made to it from then on.

Sorry, can't help there. I don't use Moray

Oops, need to clarify and I quote:
"On computers running Microsoft Windows XP or later, the maximum length of 
the string that you can use at the command prompt is 8191 characters. On 
computers running Microsoft Windows 2000 or Windows NT 4.0, the maximum 
length of the string that you can use at the command prompt is 2047 
characters."

And for (?all) modern Unices probably around 3Mb characters - see

I'm not sure what you're using this for, but if you're using it to pass 
some data from a program into the scene, why not write it to a file 
(already in POV-Syntax) and just include that file? It sure's a lot 
easier to handle and more portable, because the maximum length of 
commands varies with different OS's.


HTH,
Florian
