Hello Everybody, First..i would like to thank to all those who responded and
helped me with my previous quistion.I am verymuch new to povray/ray tracing,
i have a question regarding SDL.

1) is it possible to output the result of a macro in SDL into a text file??.
For example if i write a macro which would do some looping operations.. and
give out some result.. can i output this result in a file?. can i do this
with SDL or should i look into the source code of the programme.(if yes
please..
let me know where)

I would be verymuch thankful to anyone who can help me out with my problem.


thank you very much in advance

cheers

SDL will do what you want (3.2.2.3  File I/O Directives)

basically you need to create a file for input (#fopen)
then write a text string in your loop corresponding to the scene file
operation.

eg:

//start
#fopen OutFile1 "LoopOutput.txt" write

#local RND=seed(1);
#local i=0; #while (i<10)
   #local j=0; #while (j<10)
      #local k=0; #while (k<10)
         #local Rad=rand(RND)*0.5;
         sphere {<i,j,k>, Rad pigment{rgb 1}}
         #write(OutFile1,"sphere { ",<i,j,k>", ",Rad," pigment{rgb 1}}n")
      #local k=k+1; #end
   #local j=j+1; #end
#local i=i+1; #end

#fclose OutFile1

//end

-tgq

That's how my mesh generator macros work.  It makes it much easier to use the 
resultant meshes.

You can do this also:

#macro RndBalls(oFile,oSeed)
> #fopen OutFile1 oFile write
> 
> #local RND=seed(oSeed);
> #local i=0; #while (i<10)
>    #local j=0; #while (j<10)

>          sphere {<i,j,k>, Rad pigment{rgb 1}}
>          #write(OutFile1,"sphere { ",<i,j,k>", ",Rad," pigment{rgb 1}}n")
>       #local k=k+1; #end
>    #local j=j+1; #end
> #local i=i+1; #end
> 
> #fclose OutFile1
#end

then

RndBalls("rballs.inc",1)
#declare rBalls = union( #include "rballs.inc" )
