Hi all,

    I just wanted to post this image to demonstrate to those of you that don't already
know that it is possible to get beautifully smooth DOF by cranking the blur_samples up
*much* higher than the figure of 45 as used in the demonstration file focalb1.pov. I'd
always assumed that this figure was as high as was neccessary, and the grainy blurring
was
all that could be expected, but in this simple image I have attatched, the DOF is very
smooth. I used blur_samples 450 ( which may be overkill ) for this pic.
    I hope it pleasantly surprises some of you, as it did me.

all the best,

--

Fascinating. How long did it take to render in comparison with blur_samples 45?

PS: Thank you very much for your tutorial. I understood so much more than before. I do
have
one problem. I can't seem to find where the "numbered oscilloscope boxes" are for
muting.
Forgive my dullness in this respect. Please clarify. Thank you again. =)

I never doubted this could be done. But what's the render time? Is it worth
it?

Andrew, did you ever post the source to "glowball" anywhere? You got
excellent results and I would like a look at the source.

480x360 AA0.3 no DOF = 2 min 15 sec
480x360 blur_samples 45 = 13 min 47 sec
480x360 blur_samples 450 = 35 min 47 sec

As I discovered, using blur_samples 45 looked almost, if not just as good as the 450.
So
this was perhaps not the best choice of image upon which to demonstrate. Something
with
more objects further from the focal point would have been better.
