I went out tonight to three art openings around town and I was totally jazzed from seeing art. So I have come home and tried to do something before I go to sleep. This is my first sketch that is a continuation of the day before.

I was looking at things and thinking about in-between. I have made a simple patch that takes yesterday's patch but adds a cloud of random points and I can do linear interpolation between the two. It is crude right now but there are some very interesting intermediate states between objects that arrive. I have also properly implemented the Dan Shiffman sugar from his space junk sketch so I get some more variation from frame to frame.

Again, OPENGL so code will follow the image, now animated.

I made a bad VJ patch today. I have a rotating sphere made from a series of line strips with colour gradients. The patch pulses with size and colour to volume. Maybe soon I will put that feature extraction from the other day to use and make something a little more sophisticated.

It is made with OPENGL again so I have included the code below.

Another audio analysis simple patch for today. I looked into the BeatDetect object in MINIM and found that yesterday's code could be done even simpler by using the built in detector. It isn't very good but it works. I didn't do much tweaking on it but I bet with some massaging I could get it to detect my signals a little bit better.

So today's patch is a bit of a homage to Dan Shiffman's space junk patch. The patch has three magic lines that make it look great. The last three valid lines are rotatings in x,y,z. What makes it special is that those lines are repeated multiple times in each frame and a translate is performed afterwards with no pushMatrix() or popMatrix(). So the reference is moved about the sketch multiple times so that there is some interesting placement of objects about the space.

This patch uses the detected volume and onset information to draw a set of shapes around the screen with varying rotation based upon the detected parameters. On my machine the frames show up for a very short amount of time and often aren't drawn fully so it looks quite glitchy and nice. When I render it out to screenshots the image is preserved. Try squinting and covering half the image in a weird way and you will see what I see when it is running, or run the code yourself.

Today's sketch is a take on the mouse controlled ball that you can rotate and throw. I have a sphere here that is rotated by making a loud sound. I have done a rather crude thresholding but I discovered that MINIM has a nice level() call on audiobuffers that return the RMS. Hooray!

I also discovered that on a mac when you export your patch to the web it doesn't work well if you are using OPENGL. I have included the code inline with the blog, which I don't like so much but it will get the idea to you.

Like I predicted this is a much shorter sketch than on the weekends. This is going to be the way of it until I get more efficient at my changing weeks.

Last night I finished watching the first season of The Wire. I have been watching it on DVD and the splash screen and the opening scene of the show has all of these signal displays. So, I dusted off my trigonometry skills and started making some sine waves dance on my screen.

I have some ideas about how to tweak this a bit more by casting the shapes to PImages and then applying filters but I have a busy day, so that will happen another time. I expect that the sketches during the week will be shorter than the weekend ones. I think that is just how it goes.
