Single icicle with air bubbles, rendered in 4.5min.
I do not know what to think about this prototype yet.
I am happy with the irregular shapes formed by the bubbles, but not
completely satisfied with the distribution.
Real icicles are formed in layers, which I could do by (I think) a method
similar to the way I test if the air bubbles are "inside" the icicle
object.
Right now I construct a sphere based approximation of the icicle and test
against that to determine if the air bubbles are "inside" the real icicle
object. I suppose if I executed a recursive orbiting trace() of that
object, placing air bubbles as well as perhaps *slightly* varying the IOR
of each layer, I might be able to emulate something like what you see at
the following link:
http://www.physics.utoronto.ca/~smorris/edl/icicleripples/icicleripples.html
Any thoughts?
Branching as seen in the following link is next:

I agree the distribution is not right, but the bubbles do add a great deal of
interest to the icicle. You are certainly on the right track.

I hit the 1 million blob component limit using the air bubbles...so
unfortunately I will not be including that in my first alpha release. :(
On the other hand, they are useless to even have unless you are looking
fairly closely at an icicle...so for general use this will not be an
issue. I will re include that functionality in alpha 2.
Alpha 1 will be released as soon as I clean up the code and polish a few
things, probably hours away now.

It may be a viable, if not totaly satisfying, compromise to difference
the air bubbles using a second blob, used uniquely for that purpose.
One blob for the icicle and a second, or 2 or 3 in extreme cases, for
the bubbles.
Normaly, those don't realy contribute to the overall shape.

I postponed the alpha release for a bit to integrate duplicate avoidance
,
nearly done with that now, so maybe that will help that as well as impro
ve
general performance.
I suppose a separate blob would be an option, thank you. :) I will explo
re
this issue more once I get the alpha out.
