I make glass with wings3d. And I tested glass and caustic efects. I like the
result. what do you think?
Regards.

Frankly, I like it.
The stem on the left glass looks a touch too thick. The background and
other surroundings could be made a bit more interesting. But yeah - nice
image!
I notice the caustics have a slight grid-like pattern to them. I'm not
sure if this is an insufficient photons problem or whether it's due to
the edges in the triangle mesh...
(Either way, pretty minor detail.)

Thanks.. I think that it's due to light source's angle. The wineglass is
tall...

I'm afraid <Orchid> is right. I expierenced the same problem in my picture (look
2 threads before; "ouch..") with "mesh"-glasses. The first dozend photon renders
gave always some kind of grid like pattern or even isolated sparkles, until I
raised the gather radius to smooth them out. But be aware, that your render time
might get quit long by doing this.
Apart from this realy nice modells. Someone told me, that the quality of a
wineglass is reciprocal to the thickness of its stem. So making the stem thiner
would make it look more elegant and "expensive". ;-)

The caustics are nice...

Very nice! I am always impressed when people use photons and caustics. It is
something I am (still) a little afraid to use, mainly because of the
involved render time...

Hmm, you are may be right... I have look at your "ouch.." picture. The
light's pover or finish parameters are low. Yes,the wineglass's stem is
thick. it's very luxury furniture:) This model is made only for the test.

Thomas, thanks. Povray is very faster then other render engine. For example,
I tested this glasses with yafray, render time is too much.(1-1.5 hours) But
with povray 10-15 minute. if pov team improve the light system, Povray will
be great then vray, kray, yafray etc. I hope this.
Regards.

My photon settings:
global_settings {
max_trace_level 35
assumed_gamma 2.2
ambient_light rgb< 0,0,0>
photons {
spacing 0.05
autostop 0
jitter 0.4
count 1000000
media 0
max_trace_level 25
}
}
.....
light_source {<6.4,11,6.5>
color rgb <1,1,1>*1
media_interaction on
photons {
refraction on
reflection on
}
}
.....
object's photon settings :
object{
.......
photons {
collect on
refraction on
reflection off
target 1
}
}
is there any problem ?
