Generative Flowers II on mocoloco.com
My latest video art project Generative Flowers II was mentioned on Mocoloco.com the other day!

Be sure to check out the video and HD frame renders on the project page!

I was also asked to further expound on the project by Dave Miller for his art Blog some of what I wrote is below....

Generative Flowers II was created in a software program, in this case Adobe Director MX 2004. I chose director because it is simple to use, supports object oriented program structure and provides rapid results. I created several classes of objects designed to communicate with each other to create the animation. There are flower objects, procedural objects, an event manager for syncing to bpm and a rendering object for rendering out the frames. All the objects check with the event manager to draw in sync with the music.

The flowers are drawn by performing a color fill through a greyscale alpha channel extracted from a masked photo of a flower species. All the flower objects select their colors arbitrarily. The flowers on the corners select their alpha channels arbitrarily as well. Since the installation space has two huge HD screens facing each other across a courtyard I wanted the two screens have different yet connected video. So the central flower alpha channel is chosen incrementally making the central flower species a common thread between the two videos. The flowers are always drawing on screen every frame with 5-10% transparency so if things draw over them they fade back in over what has just been drawn.

The procedural effects objects then perform a pixel sampling and drawing function on a screen grab of what is below that instant. The object divides the screen into a grid and samples colors from inside each square. Every iteration it fills a square smaller than than the one before in arbitrary increments. This creates multicolored concentric squares from the surrounding color scheme.

Lastly there is a slight vector distort applied with transparency over the whole frame that causes what has been drawn previously to blur into the background adding a strange sense of depth.

The program runs in real time in standard NTSC or PAL resolution but a renderer had to be implemented for the HD output. I used Werner Sharp's Image Export Extra to render out all the frames as PNG files and re-assembled them in Sony Vegas.
