The generative arts are going to be shown in Playful Media, which is the showcase of BScCM, the Bachelor degree program I graduated last year. This is going to be my 4th year joining the exhibition(2010, 2009, 2008)! If you are in Hong Kong and have time, come to have a look!

It’s almost half a year, coding a piece of generative art everyday using haXe and openFrameworks. It was certainly fun and educational to me, as I had to keep reading, trying and mixing all those generating methods, brainstorming new algorithm, looking for best programming approach etc. Doing all those things everyday sharpen my skill a lot, and I’m really excited when people tweet about them, leave comment here or over Flickr. Thanks guys!

However, I decided to stop continuing the journey (at least for a while). Occurring to me often in the last few weeks, I either spent too much time on one piece, affecting my school works, or because I have to finish some urgent things, I tweaked only a little on the previous code, resulted in producing an unsatisfactory piece. I was sick and had a fever last week, which became a good time to close the project.

I now have more time to play with other interesting ideas, and finishing the works that queued up. hxOpenFrameworks will continue be developed, of course. Let’s expect some OpenCV, Kinect (OpenNI) and other goodness

Finally here are the selected pieces I made in June:

Kept the fractal circles idea going.

Some more saturated color with complementary color scheme.

Reduced opacity, the circles merged nicely to each other.

Simplified but surprisely eye-catching vector-style flower.

I ported Eugene Zatepyakin(in-spirit)’s AS3 FluidSolver to haXe and started to play with it.

Here I put several rotating color sources in the center and push out dark red colors. Pretty horror looking.

More sources, larger radius. It looks like an eclipse, does it?

An eye-catching fire ring. The key is to add color and force periodically other than continuously.

Simulating the diffusion of ink on paper.

A cup of generative latte. Think I can build an app for making coffee art.

Another color, another pattern.

The fifth month of doing a piece of generative art everyday using haXe and openframeworks. As a reminder, all the pieces can be viewed from my Flickr set. Also the haXe source code for generating those images can be found in the description in the corresponding Flickr page. Here below are the selected pieces made in this month:

Drawing only part of the lines generated by midpoint displacement algorithm can give out some interesting unknown creature contours, looking into each other’s eyes.

Another arrangement. It now looks like an island.

Used a algorithm that I read from somewhere, that start with a point with some color, for each iteration the color spread to the neighbors with a little variation. I really love its oil-painting texture.

Increased the spread’s random factor, allowing it to spread a little bit backward.

Keeped changing the spread implementation. This one keep increasing its hue from the center with a probability of reseting itself (to red).

Made the spread much more unstable and let there be more than one starting point. Resetting the lightness to 0 periodically gave out interesting organic layers.

Well, a beautiful rainbow color cup water mark on tablecloth…?

Played with fractal patterns. Full of circles in different sizes and positions in ratio.

Used only small circles. Pretty cyber-looking.

Used solid-filled circles. Colorful snowflakes.

Simpler smaller patterns.

Here comes the forth month of doing a piece of generative art everyday. Every time I ran out of ideas, forcing myself to code brought me some unexpected results.

It’s a starry night on a overcrowded planet. A simple but beautiful piece. Nothing complex there, just some random circles/rectangles placed together with a very thin layer of perlin noise as cloud. Be sure to click on it to view it in full size.

Discovered an interesting wave pattern while trying to implement midpoint displacement algorithm.

Below is a typical mountain created by midpoint displacement algorithm. Notice the sky and the mountain shares the same algorithm.

Let it displaces in color space instead of xy-plane.

Same as above but with slightly different painting method.

Changing the input lines to circular form created a perspective. It’s like the grand canyon is undergoing sandstorm.

I’ve also tried making procedural cloud from old-school perlin noise.

Applying perlin noise in some mixed strange color spaces(YUV, XYZ, HSL) instead of regular RGB.
