Created in Processing for the Major Project 3rd Year module of Creative Music Technology at Bath Spa.
What you can't see is the direct control offered by the Wiimote, which can change colour, activate pulse circle, fire out particles, change arc texture, manipulate camera distance and angle etc.
Many of the elements are automatically audio reactive (via 16 FFT bands) - colour, pulse circle, particle throw, arc width, arc opacity, arc distance from centre sphere.
The centre sphere and each particle are actually flat 2D vertex shapes with a texture to give the glow effect. No matter which angle the camera is set, they are always at 90 degrees so they look like spheres! This was an alternate method to actually using 3D primitives which would easily slow the sketch down. I'm also using OpenGL for the 3D.
Particles are attracted to the centre sphere (i'm using the Traer Physics library) and fired out on occasional audio event, and also directly via the Wiimote trigger button.
