This is so strange.
If I create some objects w/ a while loop POV says I'm out of memory.
This happens even if I give POV 3.1 96MB and have only two objects in the
loop. I can put in as many as I want by hand.
Is this a bug or am I doing somthing wrong?

    As a raytracing newbie, I awat an anwsore.

Are you sure the loop ends? If you control the loop with a counter 
variable, but forget to increment the counter, it will keep looping and 
creating objects until it runs out of memory.
#declare K=0;
#while(K<10)
    ...
    #declare K=K+1;// If this isn't here, the loop will never end
#end

I know my way arond C++, Lingo, BASIC, and POV-Script.
And yes, I do know how to close a loop, thank you very much.
Have any other solutions?

Can you provide us with an example of what is causing you problems.
Anything else we can offer would only be guess work.

  Hi, David. Please also pare down the scene to a minimum necessary to
reproduce the problem.

OK here you go:

#include "colors.inc"

camera{ location <0,2,-6> look_at 0 }
light_source{ <40,40,-30>,color White }
#declare i = 1;
#while( i <= 2 )
    sphere{ (x*i)-2, .5  pigment{color Red} }
    #declare i = i + 1
#end

Works fine for me.  Less than 65 KB of memory used.  Are you using POV-Ray
Mac 3.1g.r2?

Well, you missed a semicolon on the incrementing #declare, but that code 
worked fine under both 3.1g.r2 and MacMegaPOV 0.4 even without the 
semicolon. What version are you using?

Yes Thorsten, I use that version. I do not know the reson, but some times
that code will work for me and sometimes it will not.

As much as I would like to help, there is no way I can if the bug cannot be
reproduced.  The best solution I can offer is that you keep looking, and
once you have a scene which always reproduces the problem for you, e-mail it
to <mac### [at] povrayorg> and I will see what I can do.


      Thorsten
