Marbles

Thursday, August 6th, 2009

I meant to move on from all-ellipses all-the-time already, but I wanted to try some interaction effects. While adapting one of my previous sketches, I stumbled on this neat marble effect that I’ve been playing with for a few days. Though it started as a happy accident, it’s good enough that I think I might actually take this one further and produce some sort of tangible item.

But that’s going to take some time and research. In the meantime, here are a few conveniently wallpaper-sized images I’ve saved out, feel free to nab one for your desktop:

Bezier Stalks

Friday, July 24th, 2009

So after yesterday’s Bezier celebration I thought I’d try a more structured approach and see if I couldn’t capture some interesting movement. Reducing the number of objects down to 3600 and plotting them along a grid as a start, I got the end points and curves moving along Perlin-assisted paths in kind of a wind-blown look.

Still all in 3D space of course, so I saved out a quick capture with some viewpoint shifts and generated palettes. (With the latter you can pretty clearly see that not everything that’s generated is usable since I have to cycle through a few different palettes before I get something decent).

Generated Palette

Thursday, July 23rd, 2009

Okay, the generated palette idea was easier than I thought. Importing the photo into an off-screen buffer and grabbing some random pixel values makes for a fairly quick and easy way of generating an interesting palette. Here’s the photo:

And here are a few of the results:

Ellipse Ribbons

Thursday, July 23rd, 2009

I’ve been playing around with a variation of the radial sketch from my last post that plots a few thousand ellipses along a Perlin-randomized trajectory. I first spent a bit of time converting the ugly coordinate arrays to a cleaner object array, added a custom palette, and then added a bit more control over the view in the form of mouse-enabled 3D rotation and mousewheel zoom.

I’m not done with this sketch yet, I’m going to try generating a random palette from a photograph if I can get that working. For now here’s a dump of some of the more interesting stills:

radial-182140

radial-469179
