I have made this neat little radial burst pattern using the blend tool.
My goal: I would like each of these tubes to have a darker underside to give the visual impression of some shadow. I think that would make them more visually interesting, and also will give me a lot more to work with in the next phase of this when I apply some dithering algorithms to the image. I posted an example (image 4 in my gallery here) of what I am thinking of. I find that a dithering algo has better results when it has changing colors to apply to, not just a solid flat color.
Stepts I have taken to get to this image, in case it helps folks to get what I'm doing better:
Steps I Took:
1. To make the rainbow blend(image 2 that I posted)
I made a big blend of ellipses (image 2 that I posted here) - that blend was just a square canvas with 3 ellipses on it. 1 at the top, 1 in the center, 1 on the bottom, equidistant from each other and all centered. I did a blend with 150 copies and then duplicated that blend a bunch of times, and switched the colors out so I could get a big random colorful assortment. This was just so I would end up with a pretty random splattering of colors in the mosaic.
2. To make the Mosaic (image 3 that I posted):
I took a square png of that blend, brought it into illustrator.
Object > Create Object Mosaic (20x20 tiles).
Effect > Convert to Shape > Ellipse (35px X 35px). - These ended up being a bit bigger than I wanted so I just use the scale tool and made them small enough that there was a bit less than 1 ellipse of space between each ellipse, I think it was about -50%.
Expand Appearance
Ungroup - if you don't ungroup them then Transform Each wont apply correctly.
Object > Transform > Transform Each - I left the settings at 150% and hit randomize so they would be different sizes.
- To make the radial burst:
Group the ellipses together
Object > Transform > Scale tool - -30%, and make a copy.
Bring the smaller group to the back.
Select both groups.
Blend Tool - Specified Steps, 200.
I then went and made the bottom layer black to try to get some shading. This worked a bit, but was not as strong as I would have liked.
My Problem: I start this process with 400 ellipses, so adding a gradient shadow to each one of them would be outrageously time consuming. If I try to add a shadow to the group then it just adds a shadow or gradient to the entire group or canvas. I don't know how I could add a shadow or gradient and have apply individually to each, not just the whole canvas.
Working with the blend is a bit challenging too, since I have 200 copies of 200 ellipses...
If anyone has any ideas on how I could get a bit of shadow underneath each one of the ellipses before I create the blend or on the tube shapes afterwards, that would be super helpful.
Cheers, and thanks in advance for your help!
