Scripiting Library.

Hey FF team, congratulations for the new step. Really interesting this new feature. I'll check it out.

Do you guys intend to make a library for scripts as for filters? I mean, where members can share theirs scripts? It would be cool for those like me that aren't so good with programming languages. ;0)

For a while, folks would use this thread for posting their scriptings in case they want to share it with the community. ;0)

Cheers.

Awesome.

Here's my first "Scrippet" (script snippet): Proportional gradient.



Proportional Gradient Scrippet.ffxml

Hi Lucato, you're welcome!

Here's another one with pixel-based control.

Pixel-Based Grid

It will be interesting to see whether we can generate some patterns from the wishlist now via the new script components. Of course, I'm blissfully (and hopelessly) unencumbered when it comes to scripting, so others will have to give it a shot.

Anyone up for a Logarithmic Spiral?

Yup, nice one 3D! Thanks again.

I've been playing with ThreeDee's "Proportional Gradient" script, and it appears that the resulting gradient is still affected by Size even if the flag is turned off. Is there a way to make Map Script components independent of Size?

Speaking of flags, what is their use?

Dilla, I think its something along these lines if you want x and y independent of size:

function prepare()
SCALE = SIZE / math.min(OUTPUT_WIDTH, OUTPUT_HEIGHT)
end;

function get_sample(x, y)
local x_no_size = x * SCALE
local y_no_size = y * SCALE
end;

Following up on my previous post, here's a variation on ThreeDee's scrippet that allows you to set the grid line color and fill to arbitrary color or map values...



Grid Script Component.ffxml

Hmm... well, I just began playing around with LUA. But aside from the advanced stuff it's really nice how you can throw in any formula and end up with pretty cool stuff.

Here's a classic and a tribute to my highschool math formula that was saved on a TI-83

function prepare()
value1 = get_slider_input(NUMBER)
end;

function get_sample(x, y)
w = (x+(value1)*3*math.sin(y*x))*0.2
u = (w+(value1)*3*math.sin(y*x))*0.2
return w, u, w, a
end;

Here's the first script component I wrote yesterday (I'm still fairly new to FF, so it took me a while to figure out where the component was being stored). This one takes two input maps and outputs a new map organized as a variable size grid whose cell contents are randomly chosen from matching regions of the input maps (sort of like the game of Concentration). The color of the (optional) grid lines can also be specified using another input map/color.

For some reason, the script input editor won't allow me to set the lower bound of the line thickness input to 0, so the grid line thickness is 1 less than what you actually specify (i.e. if you set 1, no grid lines are drawn, setting 2 sets a grid line width of 1, ...).

ThreeDeee, this is a very interesting and important topic -- we're thinking about providing an API for randomness that is not prone to patterning artifacts of random number generators seeded by sample coordinates, and, at the same time, don't have the problems associated with Perlin-based noise (e.g. reduced dynamic range.)

(I haven't checked the snippet yet -- too busy writing the help.)

Hi Vladimir,

Glad you find it useful. Yes, it would be nice to have that functionality, and a way to connect it to the global Variation slider if at all possible.

As for our planned randomness API, we may decide to pre-seed it with VARIATION automatically (while allowing to add a "local" seed.)

Variation slider: Oh, excellent, got to check that out. Haven't gotten that far in investigating the possibilities.

Randomness API plan sounds good.

Lines Scrippet.ffxml

An interesting sort of thing happens when you reduce the Size, Pixels with the Lines Scrippet. The lines cross mainly in the original image area, since their coordinates fall there, but do continue in the whole image area.

Hi Ronjonnie,

That Water Splash filter was an unfortunate victim of my operating system upgrade -- it no longer exists.

But maybe I'll get inspired to rebuild it with 2.0 one of these days.

Hey ThreeDee,

Thank you for the reply. I thought you were mad at me for something & I could not figure out what that would be.

I am SO SORRY to hear the bad news about the loss of the Water Splash filter! That has to be one of the most SUPER COOL & Most useful filters I have seen in a long time!
PLEASE PLEASE find the time to rebuild it, I love it & can make good use of it. OK.

Have a GREAT weekend!

Ron

Thanks for sharing, guys.....they are helping me to learn it.....especially like the Lines Scrippet.....

Carl, check out the Berestrokia sample from Vlad/Egret. I have an idea of writing a tool to create a bomber particle builder from a png.

Only problem, I wont make a Windows version, will be Mac OS X only.

where was that Totte? your gona have to give up that mac and give windows a go

ThreeDee, where have you got the noise formula for your RNG snippet?
Could you give me a link?
