simulating depth of field.

Just wondering if there was a way to simulate depth of field without using a camera.

I'm using OPENGL to render my sketch, and the object in the center of the sketch can be rotated, so I wasn't sure if I could simulate depth of field somehow so that when the object is rotated, it's slightly blurred behind a certain point.

Or, if blur's too intensive, I'd also be happy with just lightening up the stroke.

Any assistance is greatly appreciated! :)

So I found something that sort of solves this problem.

It's a really self-explanatory library that allows a bit of customization on your part and is really easy to incorporate into your code. It doesn't blur anything, but allows you to alter near and far color. The only problem I've encountered is that I can only use OPENGL with it. Although it states that P3D should work, it hasn't for me (at least on my current project).

Anyway, hope this helps for anyone curious and looking for a pseudo DoF simulator! :)

Interesting. i came across this library long time ago and it was already broken and didnt work with the latest version of processing. Now as you mentioned it again, i tested it and seems like it is working with openGL as you mentioned.
P3D still doesn't work though...
