| Hi!
1. Is it possible to make anything like a mirror in vrml??
If yes - how?
If not - are there any good ways to simulate the looks of a mirror
(let's say a mirror in some room) ?
2. Are there any good sites that would deal with interior modeling
techniques and issues?
3. (btw) Why are there so big diffrences in what vrml plugins show, when
using diffrent plugins? I've been using BS Contact for some time, and I
wanted to see, whether my world looks the same way in other browsers and
I found that it looks completely diffrently...
Thanks in advance!

Only by doubling/flipping the object over a plain transparent surface 8-(

The newer versions of the white_dune-0.27beta editor has a flip x/y/z
action....

If it really looks completely different, you possibly used a
browser dependend node, see "

The old "boink" demo works with all browsers and also show a
example of fake mirroring:

Thanks for those examples!
I agree - they are all very nice, but how do they work??
Reverse engineering 70kB .wrl files is not really the thing I'd like to
do in the next 2 weeks :P
Are there any tutorials how to make such mirrors?
I was googling some time, but didn't find anything reasonable 8-/
TIA

Look under the floor of the boink or penguin demo, and then you will
see the trick: i it simply the same mirrored object behind a transparent
wall, and the mirrored object is moved mirrored to the orginal object.
This works only with plain walls.

Ok - I just thought that the 'miroir' demo was done in some other way
because when I walked off the room (or through the mirror) nothing was
there, but now I found that it was just a ProximitySensor which swiched
off the reflected room :)
So it seems that it's just like you said :), that the only way is 'Only
by doubling/flipping the object' :/
Thanks

Well, no, but it's the only one (except making a screenshot of the
scene) that works in all browsers. Here is another way, but that
requires BS Contact 6.1+ :

As the mirror is a CompositeTexture3D, you can put it on a simple
square for example, without having to hide what's behind the mirror or
having opaque walls.

Welcome to Cosmo Player 2.1.
Assuming URL is not found 'http://www.wildpeaks.com/vrml/no_cache/mirror_sample/sample.wrl'.
# File is empty
$ gzip -cd sample.wrl | more

How is this file encoded ?

It's crypted, not just zipped.

What is the sense behind publicing a crypted file as a example ?

Just to show that there is another way beside doubling + inverse the geometry.

Well my UNIX world includes Linux, FreeBSD, IRIX, Solaris, MacOSX and
M$Windows cygwin. This is not very much.
But how small is your none UNIX world ?
M$Windows, BeOS, Amiga and Atari ? 8-)

| Whoa!Folks keep cool auld Jake is lost here. Lets not all fall out
over silly things. I am a mere simpleton when it comes to computing
just old crappy windows here but it does it`s purpose for me. Lets
not get into geek superiority wars here we have enough on our hands
with plonkers trying to mess with vrml as it is.
