super squirmy

Ooh, another great idea.

Gives a nice gothic decor touch to the letters and dingbats.

yep, very clever, corvus. definitely going in a good direction. i had played around with a 'wrought iron' filter way back, but never could get it looking right. yours definitely has that wrought look to it. but, you're inputting the raw images and shapes and then texturizing them, right? you and 3D shld get together and do the whole thing in FF. that would be cool as hell, also.

Yes, that's right: I'm inputing the heightmap shapes. Here's an example of what one of my test shapes looks like.

I've noticed that I should stop using jpgs as inputs. You don't notice it normally, but there are JPEG artifacts which start to show up sometimes.

Maybe something like this would work:

Here's another

Here's another test: looks sort of art nouveau. I'd like to get the parts to be more inter-weavy

Latest thing: Working on a landscape-maker thingy.

Affirmative.

Yes, it was more of a proof of concept.

Here's a more progressed version of the same. It's a bit hard to control. I probably wont develop this further, but feel free to tinker with it.

Here's something fun I was working on. It takes an image and makes a around it of metal, complete w/ scratches etc... like a shield. Sort of reminds me of auto body paint.

Well, the incoming image has an alpha. I extract the alpha, blur it, and then hit the blur with a threshold. ( It mostly works - as you can see the width I think a better way would be to use high pass.

I would post this, but FF crashed on me and killed the filter.

What I've found is that I absolutely cannot edit a filter AND have photoshop running. I can run filters from photoshop... no problem. But if I edit the filter, it's as good as dead.

And now for something completely different;
Have been fiddling around with ways to squeeze the maximum randomization out of filters. Came up w/ this thing which generates high contrast shapes... lots and lots of them.

#3 one more

Yeah, it rather looks like it, doesn't it? What amazes me is that one can get so much apparent variation out of one filter. Particularly all the fun japanese-like patterns.

See, I never understood why that resource leak was so big a problem...

Yep, I made that quick little test for you, and I saw that fiddling around with the controls a bit made some interesting patterns. So I put an offset, a mirror, and a kaliedoscope node on it, and added controls.

I actually learned something cool: (Maybe you guys already know this.) I've been thinking about around how to make filters more highly randonmizable. I've noticed that a lot of the randomized output is just sort of mush. Alot of the interesting stuff that happens is at the even fractions (0,50,100). So, what I'm trying with this one is where I'd normally put a slider control, now I'm putting an IntSlider with a max of say, 5, remapped from 0-100.

Now if I just need to figure out a way to get color harmonie out of FF...

btw: this might be a dumb noobie question, but is there a way to do simple excel-type math on inputs? Like, say I have an angle control (A), is there a way to make it output A - 30? Or = (A-30)/ B ?

Ah, that's a good trick w/ the reverse remapping.

Hmm... I see.

Would there be a way to do it using curves and curve math?

using cracking and branching w/ planetizer filter. cracks look strangely natural, like ice

Yes, but the method works for the green inputs only.

Working on a V2 version of my 'Spacehulk' filter. Essentially started over. It's much faster now. Am pretty pleased w/ the progress so far...
