I am pretty happy with how these came out.  Note the interior detail.
The sharp eyed will also spot that the shadows give the fake image away.  I
used a standard IOR statement, not photons.

It would be nice if there were an easy way to have POV consider a 
transparent object to be opaque for shadows...it would actually be more 
realistic for this kind of thing.

Maybe I should dig out my schematic include again...

nice modeling.
Try:
object {Resin_Part pigment {Your_Pigment} no_shadow}
object {Resin_Part pigment {rgb 1} no_image}

You can try photons, or if you don't want to delve into that, try caustics.
You may also want to play with fade_distance and fade_power.

huh?  what!  a schematic include?  cool!  can i have it?  please?

"ZSpider"? Are you the "Spider" that used to hang out on these groups?
I posted about it about a year ago:
http://news.povray.org/povray.binaries.images/13598/
But it seems I never posted the actual include. It might need some 
updating for POV 3.5...I'll have to go dig it up.

i've been posting off and on for about 3 years, chris, but i've
either been zspider or miker.  if the guy you are thinking about
was knowledgable, then i definitely wasn't him.  hahaha.  thanks
for looking for your schematic include file.  mostly i think of
silicon stuff nowadays, but now i remember somebody a while
ago had a very nice render of some old time tubes.

thanks, miker

Nice - but don't forget a "D-ring" at case base or different lead
lengths for a key.

The ring is there, but you are right- I need to flatten one face.  The
lead thing I will fix right away!

OK, I'm happy :)
I notice one of my hi output leds has the flat across the pins, not
against the cathode. Not sure why. Its the only one I've seen like
that.

May I ask a dumb question? (if not, please don't read on). Ok, why are you
having problems with getting the interior image to cast shadows? I can't see
the problem in that. Aside that, I always loved leds and my own attempt to
model them wasn't good. But these will be quite realistic! The textures just
need to be better and I look forward to see their light turn on.

Regards,
Hugo

I just didn't put the caustics on because I was trying to get the bugs
out before doing the long render.  I'll turn them on and do it over if you
want.  At first, I wasn't sure how to do it, but I know now- it just helps
to take the time hungry steps out until the final render, of course.

Cheers!

Well, excuse my red face- the caustics are pretty fast- but they don't
look that good.  I guess I'll do the photon thing next.

Here is the photon render.  Not bad.  It ran in about 65 seconds.

65 seconds is pretty fast. But I think the shadows now look like they're
being cast from an opague object, and have you tried photons_off for the
glass?  I'm not sure the look is quite right. Maybe it's because real leds
are made of plastic (of some sort) and not glass. For the realism I suppose
you will adjust that too.

Hugo

Absolutely- still tinkering, of course.

That's pretty much what you will see in real life. Most of the light is 
refracted away from the shadow, leaving it dark. It spreads out after 
being focused inward, and is barely visible when the LED is far enough 
from the surface the shadow is cast on.

They don't look much like glass to me, they look pretty much like the 
plastic that is used in real LEDs.
