Title: Depth of field indication in the viewport?
Post by: Kost4d on 2017-09-07, 13:11:31

Hello!
Is there any way to show depth in viewport, maybe as plates or rectangles? It would be very hepful! thanks!

Like this?

Can also be handy as a helper utility, tho not much in the case of physical (photo-based) approach. ;)
Considering Corona's physical camera properties be aware that DOF blurs up to infinity.
It's not the same as the fake DOF (post fx) with cinema's AR, where you can set max & min for both (front & rear) independently.
Tho you can always generate the depth pass and use that in post for more artistic control.

BTW
DOF intensity depends on:
a) Lenses:

• Focal Length > Smaller Focal Length = Stronger DOF
• F-stop > Wider Aperture Diameter = Stronger DOF

b) Film Format (analog) / Sensor Width (digital) > Larger the Film or Sensor size = Stronger DOF

Until IPR comes to play... enjoy Experiencing & Learning photography :D

Thanks! I know all this :)

But it is all useful only if getting DOF as postprocess in AR, not even in phisycal render engine. Here I'm asking to make DOF indicator for Corona camera. I am wrong about AR?

Hmm, I'm not sure i get you?!

1. DOF indicator is the Focus Distance of the Camera Object.
2. You can also select an object to use as Focus Object
or
3. Set (check) Target Object via Target Tag.

"Considering Corona's physical camera properties be aware that DOF blurs up to infinity."
So, for any physically based virtual or real Camera - maximums from the Focus Distance are:
Front > Camera
Rear  > Infinity

You can only control the strength (amount of blur).
In this regard planes as DOF helpers are useless. Yet you can still use what's in C4D to help predicting & imagining a bit better...
... until the integration of IPR (Interactive Preview Render;)

Oh! Not it is much clear for me! Thanks, this us what I needed!
