Pi Mapper

Mapping View Surface View
There different kinds of projection mapping applications on many platforms and the most powerful that I’ve used so far is the MadMapper on the Mac OS X operating system. You won’t need anything else for projection mapping for the most part of possible projection mapping scenarios, but the trouble begins when you have a limited budget for your project and there is a need for multiple screens.

This is where the Pi Mapper comes in. It is a projection mapping solution for the Raspberry Pi. Raspberry Pi is a very cheap and small computer that is built around a processor that is being used in smartphones like the iPhone. It has a powerful graphics processing unit that is able to play Full HD videos smoothly.

The Pi Mapper solution consists of an openFrameworks application that runs on the Raspberry Pi. The Raspberry Pi itself runs Debian Linux. There is a web server on the Raspberry Pi that hosts the control panel web interface. You can connect to the Raspberry Pi from any web-browser on almost any platform.

Movie glitches

I want to use the original sound of a movie sequence as input values. The value of the different frequencies will be used to control different image filters on the movie sequence.

Fighting Shapes

I want to do a visualization of various shapes that are playing with each other or fighting over power. This is shown by them kicking each other and trying to make the others take over their form/color, or getting them out of the screen. The audio frequencies would decide the shape hierarchy, which one is more powerful and can convert the other ones.

Inspired by Walter Ruttmann, Hans Richter, Viking Eggeling and similar experimental films, I want to try to stay in this kind of visual language, using mainly basic shapes.

VJ Tool for vvvv

My goal is to create a vj’ing tool for loading and controlling vvvv patches. While there are existing solutions available I’ve always felt that they have some crucial problems that I want to solve with my own approach. The main thing is to make the patch as light-weight as possible which means that I will be satisfied using only one channel, displaying one patch at a time.

For each sub-patch I’ll provide twenty sliders for controlling different parameters and post-processing effects. Also to avoid the screensaver style non-changing nature of generative apps I will create a ten phase state machine to help adding some drama.

The plan is to work on GUI on Tuesday and Wednesday and once it’s done I will create a couple of example patches that show what one can do with my tool.

Time Loop

My idea is still quite unstructured but I would like to build a visualization software by combining time-slicing and video feedback.

Here’s how it would work:

First idea for a setup:

Second idea for a setup:

The results should be pretty psychedelic.

I will try to do this with open frameworks and c++. Plan B is to fall back to my comfort zone and use Flash.

Inspirations:
time-sliced video
example of real-time time-slicing
video feedback

Ping pong rhythms

I will try to make this kind of rhythm machine where eternally bouncing balls will create the beat when hitting side of the screen(e.g. bottom). The speed of each ball could be adjusted individually and there could be also an adjustable overall tempo. The size of ball could determine the pitch.

I will send the parameter values through OSC to PureData  where I will do the sound synthesis. OF app will work as a visual playground for the hidden sound source.

This is the initial phase.

Shape and color detection

I can’t be separated from my notebook in my everyday life :take some notes, references, sketches often related to my computerized life, I mean my computer. I want to improve the use of a my sketchbook, I would like to link it with some functions of my computer using symbol or colors that it can recognize to do a specific action (ex: take a photo of the page and save it in the adapted folder, open this folder, put a memo in my calendar, or be a visual controller…)

I should use the addon OfxCV.

visualising song and dance

Since it’s December, a bunch of my friends and I are doing secret santa. Given that we’re now spread across three countries, and shipping, logistics etc means that it’s become a real pain in the ass, it was suggested that we exchange drawings.

Not wanting to subject my kindergarten kid to my artistic prowess (or lack thereof) I decided to make a generative piece that he(or she) would have a hand (or two left feet and a hip) in.

So for the assignment, I want to create a program that will create a visualization that can be output as a pdf for printing. It will have circles that will be based on frequency analysis, the range running on the vertical height rather than horizontal, a few pixels over every second. The idea is that it will display, and leave the image of the circles behind with a very low alpha number (say 10%). To get the circles to display fully, my kindergarten kid has to dance very vigorously in front of the camera. Faster the ‘blobs’ move, the higher the alpha.

And here’s a dose of the music.
