I'm working on an include file that will let you zoom in on an image.
You know how sometimes you want to look at just a piece of what you're
working on, so you shift-click and drag an area of the screen (Windows
version only I think)? Then sometimes, you just can't get enough detail in
that area to get a good idea of what's going on in it?
The macro that is the main part of this include file takes equivalents of
the command line arguments, and actually zooms in on the selected area of
the image. For instance, you might add this to the end of a scene file:
#include "zoomin.inc"
Update_Camera_Zoom(<1,2,-3>, 0, "+sc0.288221 +sr0.326633 +ec0.538847
+er0.683417")
First argument is camera position, second is look_at point, third argument
tells it what part of the image to zoom in on.
After using this macro, you would no longer need to include the command line
parameters in the command line, because it will take the given section of
the image and expand it to the entire image size (preserving the aspect
ratio if you so choose). The zoomed area should look *exactly* the same as
it does in the regular image, only with a higher resolution.
It only works with perspective cameras, and you have the ability to set more
information about the camera if you want (sky, angle, etc). I also plan to
make it easier to use if you're using screen.inc in the same scene file.
My question: has this already been done, and if not, is there a high demand
for it? Would *you* use it?

Yes, I'd use it!!
No, I haven't seen this done before.

I would also use it. It'd make it a lot easier to work on detailed scenes.

I'm not sure that I'm advanced enough yet *to* use it. Nevertheless, I'm
always struck by some of you guys that can do stuff like this, fairplay to you
all.
I can see me using it in the future though, and I don't think it will be a wasted
effort on your part for sure.
Go for it, it sounds great.

I haven't heard of any one else doing anything like it.
I make heavy use of the 'partial screen'. On some scenes the render time even
for a partial is
an half hour. Your include file would work fine for a rough draft. But the run
time for a blown
up version of an almost complete picture may be as long or longer than the
complete picture.
It would be interesting to see! If ya need a beta tester count me in!

Have Fun!

So you can zoom in more than once? When will you release this macro ;o)
I'm missing it.

Heh, I put it down for a while; it's basically finished, I'm just being lazy
about testing it. I'll post a "beta" version tomorrow.
