Hi all,
Is it possible to get focal blurring with an ultra_wide_angle camera ?
I tried to obtain this effect in my current project : when I comment the
"ultra_wide" in the camera definition, it's ok, I get the desired
blurring; and when I uncomment it, I get a classic picture. Is it
alright ? I didn't see anything in the help file according to that.
Btw, I'm using pov 3.1g with superpatch 3.1g.

Depth of field is determined by the camera angle (as it is in real
life). I guess the effect is just not noticeable....

But how can I have it noticeable ?
Here is my cam :
#declare camera_location = <0,3,2>;
#declare camera_look_at = <0,1,0>;
camera {
ultra_wide_angle // if I comment this, I have the blurring
location camera_location
direction 2*z
look_at camera_look_at
angle 150
blur_samples 4 // only few samples (just for testing)
aperture 5 // if I change it to 100000, I have the same result :
// no blurring
confidence 0.9999
variance 1/256
focal_point <0,0,0>
}
What's wrong ?

Only the perspective camera currently supports focal blur effects. You
are correct that this is not documented. Either it should be documented,
or it should be rectified for those cameras that can do focal blur (some,
such as orthographic, can't.) Either way, it's probably a bug of some
kind. It's not a superpatch thing, the official version does the same
thing.

These are my opinions. I do NOT speak for the POV-Team.

Thanks, Ron. I prefer to know that it's currently impossible instead of
spending hours trying to find unreachable cam settings. :-)
