Dr. Lawrence W. Moore continues his exploration of multimedia art using the free and open source software, Pd_L2Ork. This flavor of Pure Data has a powerful set of externals and its own unique data structures that make is very useful to artists who want to combine audio and video in creative ways. In this first episode of Series 02, we continue working with GEM, the Graphics Environment for Multimedia external for Pure Data that comes in a stable form in Pd-L2Ork. One truly fascinating set of tools in this wide library of programming possibilities is particle systems. Particle systems can be used in a variety of ways to create moving visualizations that have a lot of aspects that can be manipulated and transformed by different values. Ultimately, they should prove to be very useful in making visualizations for music. Ultimately, the goal is to make an audio-reactive visualization gnerator for real time music enhancement in performance.
