Welcome! As has been mentioned, a while back a lot of people were making
these. They're easy to make in POV, but look fairly hard to make in real
life...

The experience is valuable rather or not the macro is. If you want to learn
some advanced POVing, just sit on your ass for twelve hours a day coding
scenes and ignore any RL annoyances...

Hmm... the way the box is lighted, it's hard to tell where edges are. How
'bout instead of a red box and colored planes, a white box and white planes
with colored lights? That way the different faces of the box will be diferent
colors.

Kevin,
this is an awesome start! I remember that back then when Eric Freeman
posted about a million pictures exploring this concept, I couldln't
for the life of me do one of these. I am not sure I can now either. If
somebody cares to explain, though...

I think you should definitely look for Eric's stuff, I remember him
doing a few with Gothic-style letters (which should be quite hard,
right?)

Thanks for the info Ken.
I "hope" there is a back up somewhere.

Here is something similar that I did a few years ago for the cover of a
zine (APA-L #1743, if you couldn't guess!).  Intersection of two text
objects.

This one is simply shiny, but for the actual covers I rendered about 42
different versions with different refraction values (0<ior<1) for the
Object.

| Greetings everyone.

Hello back.
This is a very intriguing image/ray trace.  Now I want to do my initials!
:-)
I don't remember anything like this being shown around here before, I see
though others say a similar has so I must have missed it or it's been too
long ago or my mind is going.
A macro to do this could be useful for logos.
It shouldn't be difficult at all (so I'll try it myself too).

Bob

I remember this one but I seem to recall a different color scheme.

Do you mean to do something like

intersection {
  text { ttf "faktos.ttf", "G", 2, 0 translate <-0.25,-0.36,-1>
         scale <4,2.4,1>}
  text { ttf "faktos.ttf", "E", 2, 0 translate <-0.25,-0.36,-1>
         scale <4,2.4,1> rotate y*90}
  text { ttf "faktos.ttf", "B", 2, 0 translate <-0.25,-0.36,-1>
         scale <4,2.4,1> rotate x*90}
  pigment {rgb 1}
}

(where the translations and scales would be adjusted for the particular
font, so that the letters just about fit within box {-1,1}), or are you
building the thing from CSG?

How gratifying to be remembered.

I posted an early version (in a different typeface and, iirc, with a
much lower viewpoint), in which each of the component text objects had a
solid color, so the intersection had just two colors: green and orange? 
Also tried wood and stone; can't recall whether I posted any of those.

In the final version(s), all the light is reflections of the sky. 
(Since it's for a scifi club, I put a yellow sun and a red sun on
opposite horizons.)

I didn't even think of using text objects for it.  That's kind of neat.
However, I did it basically how Hofstadter did it, starting with a cube and
removing bits from it.

Here's the scene, a little bigger, with the changes you suggested.  I also took
out the other light source, so that the spotlights are the only light.  I really
like this one.  Thanks for the suggestion, David.
