I'm trying to make an old pocket watch. I'm not quite sure how I'm going to
do the hands. I could cheat and use a transparent image map on a disc, but I
suppose I should do a prism (ugh, I don't like making splines) I'd like to
make the whole thing look older though. Some corrosion and maybe even broken
glass. Has anyone done broken glass before? The only way I could see doing
it is to difference a webish looking shape with the glass. That'd be hard to
model though.
Any critiques or ideas for further development are greatly appreciated!

Nice project.
Don't put hands...
Here's no time passing... It's very well... ;-)
To create a broken glass, you could use CSG
with difference beetween a semi-sphere or
rotational and an heightfield.

Interesting idea! I might do that but I did kinda wanna animate the hands
spinning :)

DOH! I should have thought of that. I did something similar for chipping
paint on a wall once. THANKS!

Is that because you can't figure out where your control points / nodes
should be?
Would a visual tool that created 2D splines for use in lathes, sors, prisms
be helpful? I am in the progress of playing around with such a tool, written
in VB, but am not sure if there would be much interest besides my own sense
of accomplishment.

not really. I just the route work. Its the boring part of POV to me.
And there is no preview short of low quality renders so It takes a lil
while to fix mistakes

That'd be awesome. I'm use to dealing with bezier curves in PS. If it could
speed up the process of making them!

hey you know that picture where there are time peices all over the place
draped over the tables and chares and stuff
what was it called
but that looks like it could be meshawarped or somehting to give a bendy
clock draped effect
thats it
thanks for putting up with me

You must mean Salvidor Dali's Persistance of time. It would be cool to do
that with this pic, but first I have to finish the watch :)

try differencing out random objects (slow, but effective).

Would this method work? (the glass is an isosurface i.e. 3.5 or port to
MegaPov, the frame is CSG)
It took about 2.5 minutes to render (without optimized max_gradient) using
photons and radiosity. It's usually under 1 minute.

Thats similar to what I want but I'm having good luck so far with my HF. I
have a lot more control over it than I would with the isosurface (in the
sense that I know my way around photoshop but isosurface math is a bit over
my head :)
I'll post my results soon.

I've made quite a number of watches myself. Take a look at this address:
http://showcase.netins.net/web/patrickd/imagesby.html
I haven't made any with broken glass to speak of. One pocket watch was made
with a single crack in it though.
Hands are usually pretty easy to me. I usually construct them out of
primitives (cylinders, triangles, etc.)

Also check out this prior IRTC from 1996. There are some great timepieces
made and there is source code
for many of them.

It's actually borrowed from functions.inc (f_crackle) with a little
inversing ;-). The shape of the container defines the shape ;-) I could
probably re-write it to allow you to change the crackle pattern like a
pigment/normal/density/.... I'm happy to post source.

so for example was
http://showcase.netins.net/web/patrickd/povray/elginpocket.jpg made witha
cylinder, 2 spheres, and a cone then flattened by scaling the y axis very
small? I might try something like that, thanks for the examples and the idea

Nice! For an old effect on the dial, you might want to add one or
two very thin light blue lines. Quite often an old watch of this style
will have a cracked and/or chipped ceramic dial usually radiating from
the centre.
Here's a good example:

Cool I'll give it a shot. So the dials are ceramic! That'll help me when
I get around to texturing that. :)

Hmm, maybe its my eyes, but I can't find the blue lines.

Note that not all pocket watches have ceramic dials. Some have nice
engine-turned gold or brass dials.

There's only one crack on this dial. It's from the centre to just
before the II (2). The line looks black/dark in this image, but in real
life I've only ever seen blue.

Blimey Patrick, where have you been hiding?
You've got some mean looking watches on your 'site. Bookmarked for
inspiration.

Also note how the 4 is written. This is used on most clock faces, that
use Roman numerals, instead of the normal IV.
As for the hands: just use CSG. That's what I would do - actually have
done: http://home4.inet.tele.dk/ibras/ur.htm

Why don't you try spatch or hamapatch (
http://www.geocities.com/hamapatch )?. They export bicubic patches directly
to povray.
Also you can try transational sweep in Moray, that's the way I managed to
make the clock I have in my site (in the objects section).

For the hands. I would suggest plotting several splines to form an
interesting hand shape and then using sphere_sweep to draw the hand.
sphere_sweep is best suited to this purpose, but you can use cylinders or my
cheap_sweep when possible to speed up render time. Anyway, after you have a
nice curvy hand shape, flatten it and you've got your hand.
For the broken glass. I would use trace against a semi-circle to make
several mesh pieces that will fit together like a puzzle to form your
crystal. You can then manipulate the pieces however you wish.
