Greetings everyone.

I am new to POV and to raytracing, and it's been a while since I've
posted anything to a newsgroup (and first time posting using Netscape's
news thing), so please excuse any screw-ups.  Attached is a little
object I made that was inspired by the cover art of Douglas R.
Hofstadter's book "Godel, Escher, Bach: an Eternal Golden Braid".  As
far as I know, he invented them for his book (according to what he says
about it, anyway).  He took a piece of wood and sawed the appropriate
bits.  Neat idea and a wonderful book, if anyone is looking for
something to read.

Anyway, I was thinking of trying to come up with a macro to make
trip-lets out of any three letters, and I was wondering if something
like that already exists.  I imagine not, but I thought I'd ask first.
I doubt it would be a very useful macro, but I'm planning on using it to
teach myself how to do them.

Comments and suggestions are welcome and appreciated (otherwise I
wouldn't be posting, I guess.)

Oh, BTW, many thanks to the way cylindrical lights are done in MegaPov.
Before I found out about that, I had to trim some of the edges of the object
in order to avoid getting little protrusions because of the light source
originating from a point.

I'm not sure about a macro for this, but there was a period a while back
where a bunch of people posted such images. Some one will probably see your
post and tell you more than I can :)

welcome to the group though...

The area that projects a  "G" looks more like an H when I look at the
cube......

That's because the cuts for the "E" go through there as well.  If you looked at
it straight on from that side (where the light is coming from), it would indeed
look like a "G".  If anyone's interested, I can post the source on
povray.text.scene-files, although it's pretty simple.  Just a box with some
other boxes "differenced" (I can't really use that as a verb, can I?) from it.

Thanks for the welcome, Ross.

Hope to hear from other people who have done stuff like this.  Does anyone know
if these newsgroups are archived anywhere?

This group has been manualy trimmed a couple of times becasue of the
resources it was taking up. The binaries.animations group has likewise
suffered. The News admin will eventually have to set up these two groups
with a 1 year auto expire but for the time being is doing so only when
server resources are strained.

To the best of my knowledge there is no publically available archive
of these groups available. I "think" news admin has a back up of the
server somewhere but I don't know for sure.

For a first post, that's pretty amazing.  It looks
really good.

I did something like this in my post, "Inspired by PLC" in this
newsgroup, dated 5-5-00.  In fact, I had Hofstadter's book in
mind when planning the scene.  Also see my post the next day on
text.scene-files.
