Omino Plugins 2.1 for After Effects

(After some back and forth regarding broken DLLs on our release two weeks back…)

OminoSuite21

By popular demand, the Omino Suite including Kaleidoscope and Snake is now available for both Mac OS X and Windows.

Notes for release 2.1 are:

  • Available for Windows and Mac OS X
  • Works on AE CS6 and Later
  • Installed manually by dragging
  • Kaleidoscope speedup with multithreads
  • Snake rendering errors with tiny holes substantially reduced
  • Minor parameter name changes (old projects still work fine)

Get it at the first link on the download page.

How To Install

In the zip file are two folders, one for Mac OS X, and one for Windows. Drag the appropriate folder as shown below.

OminoSuiteMacInstall1

OminoSuiteWinInstall1

Any problems (or feature requests, of course) please comment or email me, poly@omino.com. Enjoy!

Hi, I hope you can answer me as quick as possible, because I am having a problem with your Omino Snake plugin in combination with After Effects CC. When I am following the tutorial on vimeo about the layer and path thing, it’s not connecting to the image I am using. I also tried to put the image in a new composition, but that doesnt help. I hope you can help me out because I really like the plugin!

Hello —
The most likely two things are:
1) there’s a Bug where the snake image size start as 1%, so too small to see, set slider up to 100%.
2) the vertical-offset needs to be set to around 1/2 the height of your snake image.

That might be the issue, best.

thanks for your quick help. I am a bit further now, it is showing two circles now instead of nothing. here is a screenshot of what i see now http://oi57.tinypic.com/2psocnk.jpg. I am not able to see my puppet anymore when i click the path-layer off. I am still doing something wrong but i am following this tutorial https://vimeo.com/66024290 step by step…

Sorry for al these reply-bombing. I am further by setting the scale to 80%, but it is using my image the wrong way. the left puppet is how i want it to show on the path (like your snake) but it is turning it into the one you see on the path.. what am i doing wrong? http://oi58.tinypic.com/dbo9iv.jpg

david van brink // Thu 2014.05.29 23:2611:26 pm

Ah, yes, the “snake” image has to be horizontal, long in X and narrow in Y.

sandra // Thu 2014.05.29 23:4111:41 pm

Wow thanks for your quick reply! that worked! now another problem (hope its the last one!) when i want to set the keyframe for it to move, it is only visible in the first frame, changes color in the second en then disapears.. so i cannot set the ‘advance’ to when i want it to ‘snake’

oh, i dont know. what do you think?

Omino Plugins Link Revision

Just an administrative note. I’ve got a set of free After Effects plugins available. The old web-page links were a bit confused, especially with respect to which ones work on After Effects CS3 and CS4, and which are for After Effects CS5.

The new link is http://omino.com/pixelblog/omino-ae-plugins/, and also appears as a “Page” in the blog nav column, and should be much clearer.

AE: Omino Staragon, A Pixel Bender Filter

download: ==> omino staragon 32 <== a pixel bender filter

Just recently, Dale Bradshaw posted a rounded-rect pixel bender plugin. Pretty nifty!

It got me thinking, What about other rounded-corner polygons? It was a bit of a puzzle. As with all Pixel Bender plugins, the question is, What color is this pixel? How does a given pixel know if it’s inside a rounded-corner pentagon or not?

I stuck to regular and stellated polygons to start. One solution goes like so:

  • Divide the plane into pie-slices, one for each edge of the polygon.
  • For each point, decide which slice you’re in.
  • Decide if you’re inside or outside the edge.
  • For the rounding… decide which corner you’re nearest
  • Are you in the arc of that corner? If so, decide if you’re inside the rounding-radius.

Well, that was a bit of obsessive fun. Here’s a screen shot, including the parameter controls:

And here’s a little demo of it.

AE: Omino Glass, A Pixel Bender Filter

download: ==> omino glass 32 <== a pixel bender filter

There was a flurry of interest in "chromatic aberration" a while back, like here. I’d actually played with it a bit, simulating lens-effects, but only now have gotten around to weighing in on it.

The implementations I’ve seen work by splitting out your RGB and moving them around a little bit independently.

Here’s my weigh-in: Come on, people! The spectrum has more than three colors!

I find that five to seven is about right. I’ve implemented this combined with refraction into a pixel bender plugin.

omino_glass_title_card.jpg

Refraction happens when a ray of light changes its direction as it passes from one substance to another, if they have aaah, varying, that is, if they have different, um, refractive indexes. And that’s how aaah magnifying glasses work. See.

It looks like this.

The blue lines are rays of light moving up, or cast-sight-rays going down. It’s all very technical.

But I’ve got this Pixel Bender filter, right?

The filter takes in two images: a bump map (the refracting surface) and an image to view through the refraction. Here’s a bump map:

ripples.jpg

And here’s a source image:

Those chairs are known as “Chadwick Modular Seating”, from Herman Miller, designed by Don Chadwick, who later designed the Aeron chair, and that room hasn’t been that empty for, like, six years, after my girlfriend moved in and filled it up with shoes and stuff. So anyway.

And here’s the image, through the omino_glass Pixel Bender filter:

Now the fun part. Chromatic aberration happens when different colors are refracted by different amounts. Here’s the same image with just a touch of chromatic aberration applied:

Livens it up a little bit, yes?

The “flat” parts of the image, under the non-sloping parts of the bump map, appear undistored, and uncolored. But the distorted parts of the image have their colors splayed out a bit.

That’s chromatic aberration, comma, simulated.

By the way, you can get this effect in After Effects using CC Glass and overlaying multiple tinted copies, with slightly different settings for Height, and adding them back together. But that’s a lot of layers and settings to juggle; my pixel bender filter does it all in one at 32bpc instead of 8.

Here’s a test grid set with no basic refraction, and lots of chromatic aberration. This leaves the central green portion of the spectrum centered on the original image.test_grid.jpg

The inset image is the bump map.

We can see how omino_glass breaks the spectrum up into seven regions. It’s arbitrary, but I like the look.

And here’s a little demo showing the filter in motion, animated in After Effects, out on the ‘Tube.

Superb, thank you!

Harry Frank // Thu 2010.06.3 17:055:05 pm

Love it! I mention it in my next episode of RGTV and in a new preset I am posting for Red Giant People.

Thonbo // Fri 2010.07.2 01:251:25 am

ill try this out in flash at some point, this is great – ive been a great fan of the displacementmap filter and this add a serious take to that category

ill even try to add some lines of code to make you able to designate the starting point of the filtermap (mappoint) this is very usefull for lens effects

david van brink // Fri 2010.07.2 08:288:28 am

^ I’d love to see where you take it!

I havent tried it in Flash. (It might be necessary to restructure somewhat, I think there’s some limitations to do with function definitions in Flash vs AE Pixel Bender.)

oh, i dont know. what do you think?
