Circular Grids script

Oregonian · **Posted:** Wed Apr 20, 2011 10:03 am **(#1)**

This is a fun script to work with. You can get it here.

I made chocolate drops with it and used dd's bevel script and color curves on the results, then I made a brush with them.

The script is here in GIMP: <Image> Filters > SambrookJM > Grid - Circular...

Has Sam added the different sized circles in each layer option yet?

Nice drops there O!

They look like wooden backgammon chips to me though.dds script works nicely on them too.

Rod: I checked the script and the answer is no, he hasn't updated it yet. I'm fairly certain he'll post an update when he does. I wanted to leave a "Reminder" post, but decided it might be irritating to do that.

O: Nice beveled textured circles!

Interesting idea. I have to play with it a little bit, and see what I can use it for.

Hey PM not sure, if you just Saved as Jpg for a preview, but I would always use PNG

I always save a xcf and then save a copy as png or jpg, depending on my mood at the time. :proppeng

Mahvin another excellent addition to the script would be if it had a option to use octagons, hex, square, or diamonds.
I wonder if those shape options would be easy to add to it ourselves.
Then you could make some killer interfaces for music players and what not.

Thanks Rod. Well I guess they can serve two purposes.

I'll leave the selection option to you, but here are the calcs:

replace:

Code: Select all

(gimp-ellipse-select theImage xStart yStart circDiam circDiam CHANNEL-OP-REPLACE FALSE FALSE 0)

for squares:

Code: Select all

(gimp-rect-select theImage xStart yStart circDiam circDiam CHANNEL-OP-REPLACE FALSE 0)

for diamonds:

Code: Select all

(gimp-free-select theImage 8 
  (vector 
    xStart (+ yStart (* circDiam 0.5))
    (+ xStart (* circDiam 0.5)) yStart
    (+ xStart circDiam) (+ yStart (* circDiam 0.5))
    (+ xStart (* circDiam 0.5)) (+ yStart circDiam)
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)

for hexs:

Code: Select all

(gimp-free-select theImage 12 
   (vector xStart (+ yStart (* circDiam 0.5))
     (+ xStart (* circDiam 0.25)) (+ yStart (* circDiam 0.067))
     (+ xStart (* circDiam 0.75)) (+ yStart (* circDiam 0.067))
     (+ xStart circDiam) (+ yStart (* circDiam 0.5))
     (+ xStart (* circDiam 0.75)) (+ yStart (* circDiam 0.933))
     (+ xStart (* circDiam 0.25)) (+ yStart (* circDiam 0.933))
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)

for octagons:

Code: Select all

(gimp-free-select theImage 16 
  (vector (+ xStart (* circDiam 0.2929)) yStart
    (+ xStart (* circDiam 0.7071)) yStart
    (+ xStart circDiam) (+ yStart (* circDiam 0.2929))
    (+ xStart circDiam) (+ yStart (* circDiam 0.7071))
    (+ xStart (* circDiam 0.7071)) (+ yStart circDiam)
    (+ xStart (* circDiam 0.2929)) (+ yStart circDiam)
    xStart (+ yStart (* circDiam 0.7071))
    xStart (+ yStart (* circDiam 0.2929))
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)

(all tested)

Looks cool; also could use G'MIC Polkadots preset to get similar results. Adaptive Voronoi would be cool, but so far no one's taken this challenge so I have to use a command line stand-a-lone (Secord's ImageMagicK program is now broken) to do that.

Thanks Rob!
Looks like Sam was already working on it too.

This isn't what I thought it would be. I was picturing shapes with spaces between them like the circular grid.

These are examples of the script.

Rod · **Joined:** May 16, 2010 **Posts:** 14709 **Location:** USA

I think i am going to go ahead and create 4 different scripts one for each shape that Rob showed us.
If i set them up to show in different menu names i think that will work.
Then when i finish and test them ill upload them as a zip for everyone here.

cool idea

I renamed all my register entries so I could keep 4 scripts in the menus.

(script-fu-CircleGrid script-fu-HexGrid script-fu-OctagonGrid script-fu-DiamondGrid)

Whenever I obtain a Matrix program installer, I'll make the Scheme program available to all, lol.

Red pill or blue pill. Eeny meanie mynie moe....

Cool, mahvin. That's more what I had in mind.

This one I used 10 for the brush size. It was rough so I did a color select (black) and made a path, then opened a new white layer and path to selection and black. Used it as a layer mask.

The white area around the hexagrams is transparent.

Brush for triangle is 5 and side length 100.

Wow!

Some really creative results here using the original script and creative adjustments to it by our talented users. Very impressive.
