Procedural experiments

Ha, thanks!

That's a big speedup. My rendering times seem to be dropping from about 3min to 30s.

Can you break down why exactly this optimization works? Is it faster to run blurs in series rather than in parallel? Also, feeding a blurred input into the loop renders a lot faster than non-blurred - is this just an antialiasing issue or what's going on there?

Yeah, what happens is really that the blur (and any of the bitmap based components) internally renders a sample tile buffer (like if you saved an image at that stage and used that instead of the sub chain).

You use a lot of branching components (i.e. where one output sample is based on several sub samples): derivative, refraction and loop. That means *alot* of very close sampling. So what I did was to ensure that the blur components are the only way "into" the sub trees and that close samples thus hit the same tile that was already buffered. We sack some detail though.

Thanks for the explanation Sphinx. Makes (more) sense now.

Great work on these clockworks gears, and how they are good and realistic well done, great

Yup, 100% FilterForge. It's a surprisingly simple setup, just some gears over a background noise. The magic comes from a lighting setup similar to the one I used in the organic stuff posted earlier. Instead of a directional light I used a point/spherical source here.

wow that looks amazing, how you did this?

Damn Emme! The quality of this is amazing.

wow.

terrain dof 02

wow those images are stunning. Are those last two images generated entirely in FF (both the terrain and the DoF effect)?

hi emme, they are realy amazing filters. could you share ( digital number and lens blur) filter. thanks!

thanks! i am waiting the other filter.

The terrain itself is very similar to my Landform filter, I just added a smudge to get the displacement + the dof. I'll get back to working on the lens blur and hopefully sharing it soon.
