Simulated Depth of Field test

Created using Ultra Fractal.

An attempt to get results similar to z-buffer based depth of field without a z-buffer by modifying the distance estimator threshold distance based on the distance of the surface from a specified focal distance.
The effect is nice but needs more work to look like true depth of field and will always suffer from the issue of most colouring methods causing the colour to deviate from the "correct" value.
It prompts the idea that using more sophisticated positional variation of the distance threshold could be used to produce nice animation effects - which also prompts the idea that positional variation of other parameters such as the power may also produce interesting results ;)

Very cool! I've never seen anything like this. But it still seems parts of the image are too sharp - if you know what I mean. I think it's something that's easily fixed.

@spacecowboy5000 You are correct, what actually needs to be done is that the pixels need to be a mix of the surface point chosen without the dof implimented and one (or more) with the dof implimented with careful adjustment as to the mix proportions to simulate true dof.

take psyilocybin mushrooms, close your eyes, and you'll see this...in 4D :)

Looks like a Zerg's scrotum...

That looks so much like a zoom in of the things that collect air in your lungs!!!!

Kill it with fire!

What? This isn't a fractal. This is the respiration process of alien plant-life.

Very alive...and somewhat...disturbing. All that red, like you cut something open, and we're watching its internals move and shift and...glisten. Grisly gristle, its gonna take a while to get the image out of my head. Nevertheless, good job! (Ulp, ackpth!)
