It’s already the 3rd month of doing a piece of generative art everyday. Here are some selected pieces.

Reused previous month’s feather code to make a sensitive plant.

Backed to play with abstract geometry. I like its sketch style wooden texture.

Following one gives some nice harmonic color.

Replacing lines with circles, it’s now more saturated.

Since Martin Lindelöf made available its clothx physics lib, which is based on traer physics for Processing, I used its spring/attraction system to draw some stuff.

It is very easy to create beautiful structures with the lib.

More organic one. Stroke size is proportional to particle speed.

Linking up the particles.

Sorting the particles before drawing in each frame.

Old school generative curves. Can you hear the sound?

Smaller, moving strings.

Fixed, more complex strings with rainbow colors.

Scaling up.

Scaling down with blood vessel colors.

Even more complex strings. Simply drawing them down but not painting them frame-by-frame like the previous ones.

Colored version. It looks like coral. Maybe the algorithm is similar to coral’s growth.

Yup, it’s there. You can now grab hxOpenFrameworks via haxelib install hxOpenFrameworks. It is using a version of openFrameworks that is slightly more recent than 0.062(current latest release). All Windows/Mac/Linux is supported (only 32bit though).

For those haven’t tried haxe/cpp:

1. Go install haxe.
2. Install c++ development tools.
   • Windows: Visual Studio (Express version is free)
   • Mac: XCode (in order to get GCC)
   • Linux: GCC (should be already there)
3. Open up Terminal (Windows users please choose “Visual Studio Command Prompt” from start menu)
   1. haxelib setup
      It is need for 1st time use of haxelib. Simply press enter to set to the default path.
   2. haxelib install hxOpenFrameworks
      It will install hxOpenFrameworks as well as the dependencies (HSL and hxRtAudio). Mac user should also install Jack OSX manually.
4. Browse to hxOpenFramework and try compiling the examples.
   1. Windows: cd C:\Motion-Twin\haxe\lib\hxOpenFrameworks\0,062,0
      Mac/Linux: cd /usr/lib/haxe/lib/hxOpenFrameworks/0,062,0
   2. Open of/examples/Main.hx(previously is in the root dir, see issue 1) and uncomment one of the examples.
   3. haxe compile-{your_platform}.hxml

I continue the journey of creating a piece of generative art everyday. And I am still using hxOpenFrameworks. BTW, since I don’t have a Mac running at this moment, I can’t have a Mac build. And actually I’m still messing with the Linux build… So hxOpenFrameworks is currently Windows only. I will release it to haxelib once it is cross-platform.

Anyway, here below are the selected pieces from my set of creations.

After last time I discovered the beauty of physics, I went with some typical simulations…shooting bullets.
It is not in real-time, but a frame-by-frame rendering. It would be nice if there is a haXe binding to PhysX or something.

Following is simply putting some circles from inside of a grid of sands. Look pretty like corruption.

And then there is a series of connecting points on a circle. It generates soooo many patterns with a single algorithm, I have to align the variations in a grid. Don’t draw them on a paper, it may summon a fire ball or something, don’t say I haven’t warned you

Since I was leaking idea, so better do some old school recursive stuffs… Turn out applying color on them can give you nice harmonic color scheme, and the proportion is perfect!

I like the following one very much. It first generates an array of points according to some regular polygon math, then sorts them according to the angle from origin and finally links them up.

Same as above, but reversed part of the math so the lines point outward.

Still playing with the above idea, but applied lots of tweaks to bring the interesting parts out.

In the latest weeks, I have been trying to create more concrete graphics. It takes more time then messing around with math equations, but I have more artistic control. First one plays with circuit board like structures.

Applying Tron-style color.

Second concrete thing I created is a feather, as I really like birds. I used the easing equations(which are usually used for tweening) by Robert Penner to create the curves.

Creating a pair of wings is easy when you have feathers.

And finally, why not have 3 pairs when you simply can? Here comes a seraph.
