Bill's 2006 IRTC entry for Absence is one of the best, IMO.

I tried to emulate it but found it too difficult to do. So in 2008 I 
used a different method for the Wizard animation challenge. Described here:
http://www.tc-rtc.co.uk/member/imagenewdisplay/index176.html

The problem with making CSG or mesh models transparent, is the internal 
parts show when it is partly transparent.
It just looks a mess.

Wow, you remember it better than I do :)

As I recall, it mostly worked automagically in Blender, but I spent a long time
tidying the 1% that wasn't perfect. Of course, the daz mesh was ready-made, so
'all' I had to do was the offset tinkering, and the media.

Very nice. As a long-standing fan of the show, I keep meaning to build a tardis
model to insert in other scenes, but never seem to get round to it. Were the
plans publicy available? I should do one of my own :)

It would make a good easter egg in landscapes and architecture scenes.

It's just a shame I didn't get a chance to perfect the lighting before the
submission deadline - the version submitted had very blotchy radiosity
artifacts. I later rendered a faster, cleaner version using a large area_light
hidden in the ghost, which looked neater, but somehow slightly less real... I
should revisit it to polish it some more really.

I've mislaid my login details, but I'll take a look at this later.

My issues exactly :/

You had stopped watching by this incarnation, or this incarnation stopped you
watching? ;-) An underrated doctor, in my opinion. The show had really started
to get dark and interesting by the time it was cancelled in '89, some of McCoy's
final stories were and remain among the show's best ever.

Hmm, perhaps if I made a mesh shell of it, scaled it along its normals...

The composition made up for any flaws.

When you have nothing else to do. :-)

Thomas will reset it, if you ask nicely. ;-)
I would do it but I've left my laptop at home as I won't have internet access,
this week.

In short, what I did was to difference my model from a large box then inverted
that to get a container for the media. This meant I could use the same box but
difference different meshes in the animation. The eyes glow but I thought that
it might be atmospheric. I had not used blender then and did not know about
scaling along the normal. I must remember that.

I've thought about this and I do not think that you can do it directly in Pov,
at least in one pass.

It was the silly question mark suit, that did it for me. Suspension of disbelief
is one thing but the suspension of stupidity is altogether different.

That would give a nice aura, I think.
Even if you choose a good angle a perspective camera would still show the far
side.

Just a thought. If you differenced it with a plane normal to the camera. You
might get away with it.

Hm, I think the question mark had featured somewhere on the costume even as far
back as Tom Baker, if I remember correctly. Although not as prominently. Most
people disliked McCoy's interpretation of the character rather than the costume,
which was positively spartan after Colin Baker's psychedelic coat.

This won't work will it, all edges pointing at the camera will show up. That
trick worked well with the Daz mesh because the curved body shape only had
low-angle triangles at its horizon.

Or, staying with the mesh idea, using only single-sided triangles perhaps?

No its ok, it's just slightly more effort to do it while I'm at work, I can
easily get in later on :)

Well if you're using a suitable mesh defined externally, it might be possible to
read it into POV-Ray during parsing and do the offset in SDL. But it won't be
foolproof, and probably not always convenient. Better to use a triangle editor
to do the offset.

Found it where guys are talking about building the "real" thing and a 
great resource.
www.tardisbuilder.com ->
Reference ->
The Colin Richmond/Ed Thomas TARDIS (2005)

http://tardisbuilders.com/index.php?action=dlattach;k=-947;topic=4234.0;attach=57833;image

(not sure if this direct link works)

Anyway, my version is done by a macro that should (in case I'll find the 
time) create all the various boxes from all doctor incarnations.
ATM only Hartnell, Tennant and Smith are supported - sorry no McCoy 
Tardis yet.
