Hi All,

I'm new to POV-Ray and I have a fairly simple question (I think).  How can I
loop an entire rendering so once the rendering is finished, it just starts
right back up again?  It would be nice if I could make a large for loop so it
would render 'x' number of times.

Thanks.

What would be the purpose of that...?

Check out 'animation' in the POV documentation.

If you're using POV-Ray for Windows, make yourself an ini-File with 
settings for how it is supposed to be rendered (look it up in the 
Documentation, quite useful if you want to have "hard-copy" of your 
render-setup for backup-purposes) and just add it several (or make that 
"x" ;-) times into the queue.

I'm guessing that you want to use the output of the render as input for 
the next, and also look at Leroy's answer, animation might be of use as 
well, unless you're already rendering an animation with output used as 
input...

Regards,
Tim

I assume that each image will be different.
I may also insinuate that the last image will go back to what the first one was.

This looks like an animation.
You are probably using the windows version.

At the top of the editor, next of the resolutions, there is a text box, it's 
called the "command line option box"
In that box, put +kff<some value>
This will turn on the animation feature and start the automatic rendering of X 
frames.
In your scene, you use the "clock" variable to control the animation. It's value 
goes from zero to 1. It can be used to move, scale, rotate, add or remove any 
object or materials.
The various conditional statements are most usefull for animations. Take a look 
at #it(condition)...#else...#end and #switch(condition) #case(value)...#break, 
#range(value,value)...#break #else...#end

If you want your animation to loop, add "+kc" to enable cyclic animation.

As far as a *presentation* of a cyclic action, I'm sure you're aware of the
options of an animated GIF or simply making a MPEG-I and then using a good
player that doesn't jerk when it loops.

The cyclic loop switch in povray simply determines whether, for five frames
(Final_Frame=5) , the clock values go from 0, 0.2, 0.4, 0.6, 0.8;  versus 0,
0.25, 0.50, 0.75, 1.0.    That's all it does.

As far as making **cyclic things happen** in povray, you could, to get "N"
cycles during an animation, use hings like:

i) rotate,  like  rotate 360*SOME_VECTOR_AXIS*clock * N
ii) mod,    like translate 5*x*mod(N*clock,1)
iii) trig functions,   like  pigment {rgb <sin(2*pi*N*clock), cos(2*pi*N*clock),
0>}
