Not sure if we are all talking about the same thing here,
but I normally have a separate ini file for each animation
(of course they all look similar but not the same) and I
just run the ini file instead of the pov file to produce the
animation. If I had a setup stage I would create a new
ini file with different information and run that instead.
Here is the ini file from my latest bubble animation which
I call (not too surprisingly) "Bubbles11.ini":
Antialias=on
;Quality=0
Input_File_Name=Bubbles11.pov
Initial_Frame=1
Final_Frame=120
Initial_Clock=0
Final_Clock=1
Width=1152
Height=864
;Subset_Start_Frame=16
;Subset_End_Frame=120
Cyclic_Animation=on
Pause_when_Done=off
I would still like to play with your flocking algorithm
to see what variations on a theme I can come up with
but I will likely re-write it in Java (mostly by way of
learning what it does :-)

I don't know if this answers your question or helps you with your problem but
first of all: I never edit the povray.ini-file, I make inifiles for each
seperate animation. Then if you want to do the basic calculation only once, in
the first frame just put in an #if-statement (#if (clock=0)....#end).
Hope this helps,

Time to eat my words (yum). I rewrote your flocking
algorithm in Java and it was tough. Simple little things
like subtracting two vectors or normalizing a vector
are not supported in the language (like they are in POV)
so you have to write them yourself.
Not only that but you lose access to some of the great
utility inc files like Colefax's clock mod or splines.
I guess my respect for the POV language has gone up a
notch or two. Just had to try the alternative to be sure.

SO, are YOU going to post YOUR code? I'm especially interested in the .java
so I can make my own future modifications!

There are a few different Vector math packages that can be used, including
one that comes with Java3D (I'm liking that more and more these days).
Probably the biggest problem in going to Java is knowing which Java libraries
to use. (<commercial>And if you do a tool in the full-blown Java3D, you get
OpenGL/Direct3D/Mesa support for free.</commercial>)
I'd be interested in looking over what you've done, as in the abstract the OO
programming aspects of Java should make things easier. Then again, it might
be that these algorithms just aren't well suited for that.
However, losing access to the POV-Ray .inc files is probably a big issue,
though.

Learn to use the command-line parameters field in rendering settings. I
use it all the time. It's the easiest way to get any setting (except for the

I'll assume that you're using Windows as you've got INI files - or
that if you're not they work much like thw Windows INI files.
There's been a helpful suggestion re using the clock variable to
determine if the scene needs rendering along the lines of:
#switch (clock)
#case (0)
// First and possibly only pass - proceed
#break
#else
// Oops - we're getting animated - STOP!
fall over here please (this statement can't be parsed and will halt
rendering)
#end
but there's another solution too - multiple sections (named within []
brackets) which can be selected in the "INI Section combo-box" (don't
know if it has a real name) originally positioned under the "New,
Open, Save" toolbar buttons.
For example:
[CD-i 352x288, All noAA]
;Cyclic_Animation=on
Width=352
Height=288
Antialias=Off
Jitter=off
Output_to_File=On
Pre_Frame_Command=
Pre_Frame_Return=
Post_Frame_Command=
Post_Frame_Return=
Post_Scene_Command=
Post_Scene_Return=f ;;If error, crash
Pause_When_Done=Off
Continue_Trace=On ;;Lets you resume
Test_Abort=On ;;Lets you interrupt
Initial_Frame = 0
Final_Frame = 899
Initial_Clock = 0.0
Final_Clock = 899
Quality=9
;Set automatic bounding to work on 5 objects or more (default is 25 or
more)
+MB5
[CD-i 352x288, 11 noAA]
;Cyclic_Animation=on
Width=352
Height=288
Antialias=Off
Jitter=off
Output_to_File=On
Pre_Frame_Command=
Pre_Frame_Return=
Post_Frame_Command=
Post_Frame_Return=
Post_Scene_Command=
Post_Scene_Return=f ;;If error, crash
Pause_When_Done=Off
Continue_Trace=On ;;Lets you resume
Test_Abort=On ;;Lets you interrupt
Initial_Frame = 13
Final_Frame = 100
Initial_Clock = 13
Final_Clock = 100
Quality=9
;Set automatic bounding to work on 5 objects or more (default is 25 or
more)
+MB5
You could set up your preferred animating and non-animating INI
sections into one (probably largish) INI file that way - I've a slew
of settings for the one animation my life seems to revolve around...
Hope this helps,

Yes, this is what I meant by the "secondary ini". The batch file way
that might work out best would be to run it as a preparse through the
ini file (See Shell-out to Operating System in the DOC
[Pre_Scene_Command or Pre_Frame_Command] and check for the already
done file. "exists.exe" is probably there in your POV-Ray folder and
you could use that I suppose to do the checking.
Of course I'm only here due to the interest in your pov script flock,
I don't have any of this file checking done here myself ;)

Bob says:
Yes, the "Secondary INI" :-)
In the menu of POV for Windows you edit it through Tools/Edit
secondary ini.
I like that #switch (clock) idea, however I wonder if cyclic
animations use zero for the starting number of not... yes, it does
appear to be 0 after all.

Ooooer - so there is. Never seen that before (never noticed). I
generally go "Render...Edit settings/Render". the tools menu would be
faster/easier by at least a mouse click (well - every click matters
when it's subtracting from render time!).
