Thats 3 votes for portal heh (posted same time heheh.. and chris counts
as two cause he posted as i was writing my last one =} )

anyone else have any ideas?

BTW this would require you to have superpatch or megapov to work.
(uses the intersection that was added to compute_pigment)

Portal sound more like an object identifier than a pattern modifier or
type.

 How about "Transwarp" ?

It has a catchy ring to it and is moderately descriptive of the process.

I still prefer "portal", it is more descriptive of what the pigment does 
than "transwarp". An object with this pigment will act like a portal to 
another part of space.

A couple other possibilties:
wormhole
mirage
gateway
space_time_bending_thingammajiggy_pigment :-)

One thing that might be even more interesting would be a pigment that 
takes a scene file as a parameter. Both scene files would be parsed, and 
a ray could travel from one scene into the other through objects with 
the portal pigment. Of course, this would require extensive 
modifications to the code, and wouldn't be much more useful(if at all) 
than just one scene.

Not useful?  Might be an understatement there.  Imagine the one scene (call it
an included scene) doing things while the main scene is rendering it in as a
sphere or box or what have you and being dynamically linked, most useful in
animation.
This type of thing reminds me of the old window viewport "world coordinates" and
such stuff somehow.
http://hpsalo.cern.ch/TaligentDocs/TaligentOnline/DocumentRoot/1.0/Docs/classes/
TGrafPort.html while not exactly the same thing I suppose it mentions "Port"
anyway and that sounds about right for this so 'portal' or at least 'port' might
be good.  If the idea is to have a window on another scene part (if I follow
this at all) then I can't see a more fitting term.
Not really pigment or texture anyway is this?  I mean, could be a objectless
entity right?

I meant that having it be a portal to a separate scene file wouldn't be 
any more useful than being a portal to another part of the main scene. 
You could make it "link" to a portion of the scene that is out of sight 
instead.

Well, it requires an object to define the area the portal occupies, and 
making it a pigment type like image_map makes it a lot more 
versatile(you can use it in texture_maps to make the portal irregularly 
transparent, and turbulence might be interesting.
For my version I had been thinking of an "is_portal" attribute for 
objects. This would have been a lot more limiting.

A couple more possibilities for the name:
ray_transform (This one is very precisely descriptive of the process, 
but doesn't give a good idea of what it actually does. I don't care for 
it much.)
magic_mirror
looking_glass

There are two concepts here.  One is the portal (hologram), the other is the
camera.  They would have to work differently, I think.

Good point, if you made a security camera monitor using the portal 
pigment, the areas visible through it would change as you moved around 
the monitor.
One possible solution would be a pigment which would take the same 
information the camera takes. This would probably have to render the 
scene from the point of view of the target position and use that as an 
image map(internally). While this would be very useful, it might be 
quite difficult to code.

I would be satasfied with the portal pigment. Image maps could be used 
for security monitors.

'looking_glass', I kinda like that one, even if it is a bit off the beaten path.
I get what you mean and 'magic_mirror' kind of fits that too.

I just realized this is the multi-camera concept brought up more than once
before.

Oh! Now I get it! (Please don't talk about rays that go somewhere, just say
"camera"). OK. In that case, "portal" sounds good enough to me.
