space painter

The goal of this project was to create a software wich can help people to enhance physical and mental capabilities like orientation, coordination, stamina and memory.

SpacePainter is an application for the space-scan interface. The users are able to paint a large, three dimensional virtual sculpture-like painting. By holding the plexi-glass horizontally, rotate it left or right, the user can access three different program modes: paint, erase, zoom.

Here is a screenshot from the tracking part of the software. The app tracks the position and calculates the rotation of the two paralal lines placed on the plexi-glass.

Android Painter

This is my first sketch on android operating system. I've used processing for android (http://android.processing.org) which is a very simple to use android "SDK". You just hit run, and it runs on your attached device :)

You can draw in two modes (draw or throw), every time you touch the screen a new colos scheme is generated. The screen is slowly fading in a paper like pattern.

Binned Particle System

Optimized particle system with collision detection.
My Processing version is a port of Kyle McDonald C++ code (made for openfrmeworks)
The particle are trying to keep distace from each other, while a force is attracting them to the middle of the sceen.

As the result of these rules applied on 3000 particles, very nice, natural looking patterns can appear.

Built with Processing

physics based animation framework

The goal of this project was to create a software framework, which can generate phisics based audio-reactive animations.Here are some stills from the generated sequences.

Forgive me about the music (it was made for a tv show :-))

audio/visual games

This project was a three room installation for a press-award event. All the installations were interactive music games for the audiance to play with.

1.: Mozart room - a camera is tracking the horizontal movements of the people. The audio and the visual are generated in real time reacting to the motion of the visitors.

2.: Midi piano - in this room, there is an acoustic midi piano which can receive MIDI signals form a computer. A custom made software is transforming the visual information into MIDI music motes, so the visitors are able to play the piano using body gestures.

3.: Noise room - in this real-time video montage people are placed into a crouded indian street. The space is devided to several recangular zones, and when a person enters into one, it playes a sound sample from a database.

All the installations are based on custom build softwares made with openframeowrkd and PureData.

Liquid Image

This is a simple spring simulation. I've created a grid of springs, and to each joint points I attached the corresponding points of an image. We tested it on a multitouch table, so you could play with multiple fingers.

You can try this applet by pressing and moving the mouse over the image below. (to try this you need Java to be installed)

Flow

Flow is a physics based image synthesizer. It's based on the simulation of particle flow in different force fields. Each particle leaves trails on the canvas. By changing some parameters of the system it can create vast variety of color compositions.

You can download the "mini" version of the software from here (windows only).
p.s.: to run the software you will need a videocard that supports OpenGL 1.1.

Beat-Box

The "language" of the instrument is based on three very simple building blocks: triggers, boxes, strings. These can form complex structures due to physical parameters on the surface (friction, gravity, forces, collision, etc). Sudden, unpredictable events arise, which gains improvisation, free play and gestural expression for the user.

As for other systems (textual, visual languages), physical position (x,y) of the building blocks usually don't affect the composition itself. Topology of objects are mostly based on usage issues and ergonomic goals. Here instead, on the fly placement of the objects define the whole structure and becomes the "resonating body" of the instrument, creating a playground between multiple users, a virtual kinetic surface and the sounds coming out of it.

Download a simplified version for:
Mac OSX
Windows

By pressing the mouse you can chose from these items.

When a ball hits an object it generates sound. The pitch of the sound depends on the length of the object. As the ball travells it looses its strength so as its volume.

You can clear the objects by dragging them outside of the window. Pressing the mouse button here and selecting clear will clear all the objects.

Future plans:
- multiple sound samples
- allow to record samples from the mic (making real live acts)
- creating your own node by group an existing composition, so you can organise you scene easily.

Rigid-bodies

This is a test for using Box2D for simulating realistic body motion. It is planned to use in the next version of Animata (animata.kibu.hu).

Nervous Camera

Code: Openframeworks

This is a visual effect test for my new project...
Pseudo code:

live video -> threshold filter -> blob detection -> apply voronoi tessalation to the edge points -> remove lines crossing the screen borders-> draw diagram

Neural Network

Code: Processing

This is a concept for a LED sculpture. In this installation all the elements have the same functionality. If one node gets an electric impulse it triggers the other connected to it. In this was you can achive simple spreading behaviours. Because of the non centralized mechanism, this structure can ba applyed to any size and any shape. The input can be a human touch of a node, so this contact information can travel through space creating an abstract virtual structure in the installation itself...

simulation:
Click on the applet and press space to start a random impulse in the system. You can rotate it by clicking and dragging...

TreeGen

Generative Tree draing application.
By changing some basic parameters in the program (branch length, direction chaos, number of new branches) you can generate a lot of different structures...

CLick on the applet below to generate a new tree
