  Returning the file name. (Message 1 to 9 of 9)

Is there a method of returning the file name to a variable, of the scene 
I am rendering? I would also like to get the file path as well.
I want to do some recursive work with the output of the previous frame 
in an animation.

You can have the current frame number (frame_number), but we are weak on
the string functions. (converting the number in a string is fine, but I
do not know how to get the current scene filename, so you might have to
hardcode it)

For using the previously rendered image, add +L<path of the render
directory> in your option (especially with that settings which might be
set or not: to render all files in one directory) (if not rendering from
./ to ./ )

Thanks for your reply Le
I thought that be the case but I was hoping that there was some 
undocumented function that everyone but me knew.

It is a slight pain to change the code manualy as I save my files 
incrementally, a lot, as I make changes in the scene.

I’m doing this as a sample scene for Bishop3D so my audience may not 
know too much about changing the Library_Path in povray.ini. I was 
hoping to automate some of it.
  Maybe a feature for Pov 4.0 ;-)

I don't think so. What you can do, though, is call POV-Ray from
the command line where you can control the file names and even pass
them to the scene via generated include file.

Maybe source control should be integrated into the Windows editor ;)

That actually crossed my mind a while ago - making a full IDE type environment
for POV-ray.  I like the idea of having a project file that tracks the scene
files, included files, images, etc.  Even better if it has the ability to jump
between identifier definitions and their references across files...

At one point I was looking into existing IDEs that have the ability to syntax
highlight or 'compile' for any language that you give it a definition file for.
The idea is that it has already been done very well, and this would simply be
the reuse of existing packages.


Anyway, is providing a way to read the file name something that could be done
easily?  Could it cause problems from a security standpoint?  I'm sure this has
come up before, but if it is going to be considered it would seem to require
several variables (to allow the user to determine the names of scene files and
output files, which may be different).  Would it be better to consider allowing
a scene file to read what options it was called with?  This would be the options
as specified in the povray.ini, scene.ini, and command line - for instance, a
scene could know whether or not anti-aliasing was used.

Do you increment the end of a base filename?
Loop useing the file_exists(S) function untill it fails, then use the one
before.

I don't know why I missed it before, although it does sound vaguely familiar.
I'll probably give it a shot later this evening.

That is a smart idea, Stephen.
The scene is for Miri as it is here birthday later this month. The code 
might encourage her to delve into SDL. ;-)
