PSP or Photoshop are here for that.

what - when i need to see the last few lines of an image first? :)
yes, yes, render-subregion yada yada yada.
i said -first-, not -only-!
Lots of renderers dont start at the top left, some even start in the middle
and spiral outwards.
I tell you, it wouldn't be an altogether useless feature.
And yes, i have been raytracing too long. far too long. there's no hope...

I'm working on random-order rendering.

Well, it's not for laugh, changing rendering order might speed up
rendering: if rendering is performed by buckets, lets say 32x32 pixels,
then renderer can take advantage of spatial coherence and use various
caching mechanisms more effectively. With current option (from left to
right) rays are hit all over the scene and almost all objects are being
hit during scanning one line, thus making cacheing less effective.
Perhaps this is not the issue with current implementation, but if
someone wants to implement true displacement mapping and use selective
surface division (only this bucket, which is hit, is displaced) to avoid
problems with memory, then this could give considerable speedup.
And with really large scenes, which require more memory, than available
(thus requiring use of swap space) it could be faster as well.

What do PSP and Photoshop have to do with rendering order? Or raytracing?

camera {
sky -y
location MyCamLoc
look_at MyCamView
}
Now stand on your head while rendering...

Changing the render direction will have noticable side effect if you are
using procedural textures like POV-Ray does. I have posted two images of
the spotted.pov example scene that comes with POV-Ray. One is rendered from
the top to the bottom, the other from the bottom to the top.

That is very strange. Was this bottom left to upper right or bottom right to
upper left? I still don't undserstand why the order the rays are traced matter
so much. Any enlightenment?
