The first update is in:

- Optimized AA zones generation.
- Enabled Seamless Tiling so the component can be used in seamless filters.
- Replaced all the Profile Presets with a single Curve Editor.
- Controls are now fully mappable (where possible).

Now to make this filter feature-complete, I'll need to find a way to shade the spiral gradient like this:

To-Do List:

- Fix script error for Size = 1.
- Implement a 'Fixed Size' option.

Argh! Forum gives me the red mysterious "Message Text" message, so I have to attach the whole filter instead.

I added some minor fixes and optimizations - I'm too lazy to go over them, so find a good free diff viewer smile:-) (notepad++ supports lua syntax and has a compare plugin smile:-))

That drill mode gradient is a good challenge smile:-)

right after

-- Convert spiral gradient map to 0...1 range
spiralGrd = spiralGrd - aa_zone

try adding

spiralGrd = (spiralGrd - radialCoordinate) / 4

now that "4" is just some quick normalization constant - I'm sure there is a more theoretically correct way to normalize the output.. its here inujima and ThreeDee comes in (where did he go btw?) smile:D

That last one is oddly disturbing, in a Junji Ito kind of way.

Filter update:

I've ditched the LUA script implementation and constructed the gradient old-school (i.e. with native components), which renders about 6.5 times faster. The legacy LUA script will remain inside this filter for archival purposes.

Very nice gradient tool. Will prove very useful in some of my projects. I like the "fractal" like quality of some of the results. I've already thought of an artwork that can use it.
