I for one would thoroughly love to see a work done by you, I can't say I ever
have before.

Someone else (Xenoarch?) wrote a similar patch, I think he called it 
"hologram" though. (other names that got tossed around ranged from 
"magic_mirror" to "mirage"...)
I just got impatient waiting for it to show up, so I started writing my 
own. It currently works, but isn't very functional yet...I've been 
trying to implement the ability to use a camera as a portal (the effect 
would be similar to rendering the image from a different camera and 
using that image as an image_map, but would be done on the fly), and one 
of the problems is that the camera code assumes it is rendering pixels 
of the output image and that there is only one camera in the scene. (I 
had to make an almost identical copy of create_ray() which doesn't use 
the precalculated information for the main camera, duplicating a lot of 
code...and focal blur won't work for a while)

Followups to povray.unofficial.patches...

I have wanted a similar feature, I envisioned it as an image map created by a
different camera in the same scene, but it was a bit of a headache and caused
nasty recursions when I thought about it.

That is exactly how one of it's features will work.

It can cause recursion, but no more nasty than reflection. It will 
probably be affected by max_trace_level like anything else.

I'd noticed some OOP stuff in the code, the object methods for instance. 
Or were you speaking of the scene language?
I'm currently learning Objective C, an OOP extended version of C which 
apparently borrowed most of it's concepts from Smalltalk.

Sounds interesting, though there isn't much info on the page...
I suppose you'll want to finish the program first, though. ;-)

Well, it's nice to see the creator of this program drop in...you 
certainly started something.
BTW, if you haven't already found them, there are some messages about 
the current status and future plans for POV-Ray in 
povray.announce.frequently-asked-questions that you may find 
interesting. Particularly "POV-Team Status Report - September 1, 2000" 
by Chris Cason.

Anybody remembers the twisted TV cameras looking at their own outputs in
chapter XV of "Goedel, Escher and Bach" by Douglas Hofstadter ? Would be
nice if Pov-Ray was able to reproduce the pulsating, chaotic galaxy
images they generates on the TV screen :-)

Well, no...actually, I have no idea what you are talking about, aside 
from the arrangement of a camera looking at it's own output.

Well, there are many variables in that system...(screen pixels, scanning 
of the CRT, delays in the line, etc...), but you might get some 
interesting effects with warps and various portal parameters.

Nice to see you here!

I'd say probably the single most important addition in 3.1 is macros. Now
you can automate and calculate just about anything, though it's also much
easier to get looooong parse times. ;) There is a continuing skyrocket in
the quality of work posted here, thanks to continued development and a large
community. MegaPOV is simply loaded with great features too, and many will
be in 3.5.

Looking at the code I saw that it is just a few days work from becoming a
complete C++ source. By the way, had not POV one of the most
anti-free-software licenses I ever saw (barring commercial software), I
would gladly do this job myself.

Ah... old POVers never die, they just trace at 0 pps...
