I've just been looking into this, which is pretty much what I always wanted, coming from pixel art to CG: "Palette swap for entire 3d space" (scroll down the thread for a bit till you see the cube, to get to the real interesting stuff)

The filter lets you define a sort of 3d palette, from pairs of 2 colors. Each pair either specifies a mapping source color -> target color, or specifies 'lock source color' (so that it is the same both before and after the filter is applied)

GMIC then Delaunay-interpolate the inbetween colors to create a full smooth 3d colorcube (known as a HALDCLUT) and applies that to your layer(s)

Since it's GMIC, you can also do that via the commandline if needed.

In case it's not clear, this is not comparable to curves or levels, which just allow you to adjust color channels individually. This allows very direct control over 'voxel' areas in the colorspace (eg if you want purple to become yellow, you just set up a mapping purple -> yellow. Two color selections, and done!)

I'm excited about this!

If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

New Pro Motion release has features I conned Jan into adding to make it easier to do parallax work and save out GIFs of it.

Nice.

random things that suck: main screen (1920x1200@24") died in a thunder storm, replacement won't arrive until next month (the positive side to it: was saving up for new computer parts (CPU, board, RAM) anyway, so took the opportunity to order them now along with the replacement screen)

Hey guys, pixelation really needs a digital art section :)

I am working on a cover for a fire emblem remix album.

Here is what I have so far, was hoping I could get some feedback on it:

It's called the 2D & 3D Board :P

Liking the opalescence of the shield, but the text seems choked by that outline.

Howabout this version then? Took the original title text from FE and put a bevel on it.

Love the crazy shield design and coloration.

Now that Fire Emblem text, though . . . it's so obviously made of cheap photoshop effects it really brings down the whole thing down.
Very much reminds me of what those new to graphic design might do.

Why not let the shield speak and just go with a classy, thin, sans-serif font all white; no bevel/gradient?
And dark background to make the shield pop, with perhaps a subtle radial gradient glow behind the shield.

Some progress (memory inefficient chunk-based undo, crude switching through colours of hard coded palette):

I was thinking of doing some work with the web safe palette (6 level per channel RGB colour cube, with a bunch of colours left over for special purpose uses) but layout of this palette in most editors is a real pain which got me thinking.

Anyone thought much about or know of existing systems for better palette layout?

Pro Motion and GraphicsGale just give you a fixed 16x16 grid.
GrafX2 does give flexibility to adjust the number of rows and columns shown within its palette window but its fixed sizing is so cramped and awkward.
Gimp allows the setting of a fixed number of columns per palette.
Aseprite allow resizing sidebar size and fixed swatch size options.

Palettes made of a number of fixed size ramps suffer when each ramps on each row are offset and splitting across line breaks. (Gimp and Aseprite can layout this style fine.)
Palettes made of a number of variable sized ramps always suffer splitting across line breaks.
Colour cube palettes particularly suffer when not laid out in slices. (eg. in a 16 column layout web safe 6 level per channel is just about unusable, CPC 3 level per channel requires padding.)

I'm thinking we need some way to define contiguous blocks (ramps/slices) with control over line breaking within blocks.

Code: [Select]
// wrapping line break every 6 colours
{
breakType: soft,
repeatBreak : 6
}

// forced line break every 8 colours
{
breakType: hard,
repeatBreak : 8
}

// group every 36 colours, within group forced line break every 6 colours (web safe)
{
breakType: soft,
repeatGroup: {
length: 36,
breakType: hard,
repeatBreak : 6
}
}

// variable length ramps with wrapping breaks
{
breakType: soft,
run: 8,
run: 12,
run: 8,
run: 8,
run: 6,
run: 6,
run: 16
}
