Hey MSOzzzzzzzzzzz Good work, U R getting there, I can see one side of a very fluffy bow right now. Aren't those settings like hieroglyphics??? I actually had the right settings at one time but all was lost in crash before last

MsOz, this is done i, Sinedots, isn't it?
Because if this math can be done with Al's Illustrator (and Photoshop) technique, then you mlust have spent a sleepless night nudging...

Hi all,

I used a line-shaped brush on a path to make a ribbon. I think it looks pretty ribbonish, but when I used 'angle fade' I got some unexpected Moire-like patterns. I'm not sure how to get rid of those.

Excellent Alias, I think the Moire pattern adds to the ribbon effect.

[sPECtre]

excellent!
you did not just use a line shape, did you?
the moire might be caused by the aliasing,...

 

[MsOz]

Hi all!

Excellent red ribbon for Christmas! Actually, I think that the moire patterning is dependent on the number of "strands" used in the original sine's number of repetitions, adjustable in the top "box". If the repetitions are too close, the moire patterning occurs.

Joy, in my efforts to explore AND understand, I'm pretty much sticking with the old "3,6,9,12" o'clock method of experimenting, so that I can fairly easily duplicate my results :\ , and I get a bit more understanding by twirling a dial back and forth a few times to see how things change. This is SUCH a cool plug in...especially when you start applying layer styles to it! The 3D effects can be extremely fun!

Happy Holidays to everyone!

Mr. Blevins has some excellant material about anistropic reflections.

Anistropic Reflections

It's for CG, but he makes very applicable observations.

exellent linkage Stroker, thanks muchly :}

 

[Alias]

Thanks Al, sPECtre and MsOz!

sPECtre, I used a light (80% gray), 1 pixel line, with a single dark pixel at each end.

You are right about the aliasing. Increasing the spacing shows that only one side of each line is anti-aliased.

MsOz, what do you mean by "the number of "strands" used in the original sine's number of repetitions, adjustable in the top "box"." I have no idea of what you are talking about. But that may well be caused by my lack of Photoshop experience. ;\

I'm still figuring out how this thing works, as there really isn't a "User Manual," but some things are starting to click in my head...

The number of strands is dictated by the Inner Density Slider. The smaller the number, the fewer the strands in an image. That's the "First Box" I was talking about. The other boxes are the X and Y boxes for Effects and Inner and Outer Angles. The effects they provide are based upon 360 degree sine waves.

Here is my latest experiment...

MsOz, I haven't a clue what you are talking about, but I am impressed by your enthusiasm. Keep it up
