Yes, and no security issue with unix/linux/*x at least(1).
(1) - Maybe some obscure ways to disable a file system if one works at it.
The more tangled part is what would a command set supporting directories
look like. Then we'd have the implementation of those commands,
documentation and training of users. I saw too jr's suggestion for
system commands. I don't know...
I'll further hedge. Again due my tcl wrapper, I've not used the POV-Ray
based IO all that much. You and others, understand SDL IO better than me.
Aside:
My few, true animations I've done with my wrapper so I can do other
frame to frame work in tcl (as jr suggested useful) and more so to
see/work with the "as calculated" per-frame scene files while
debugging/developing. Being able to get an after SDL(tcl) 'runs' scene
representation is helpful.
My pure POV-Ray animation use has been: Creating a few frames where
early images are used in a final one; Tickets and promo stuff for an
arts program; A large puzzle piece image for a town treasure/scavenger
hunt where the 'animation' created the puzzle piece images which were
printed on smaller photo sized paper edge to edge. POV-Ray and its
animation capability is very useful for such projects.
