::::::::::VECTOR SYNTHESIS LIBRARY for PURE DATA::::::::::<\/p>\n

https:\/\/github.com\/macumbista\/vectorsynthesis<\/a><\/p>\n

The Vector Synthesis library allows the creation and manipulation of 2D and 3D vector shapes, Lissajous figures, and scan processed image and video inputs using audio signals sent directly to oscilloscopes, hacked CRT monitors, Vectrex game consoles, ILDA laser displays, or oscilloscope emulation softwares using the Pure Data programming environment.<\/p>\n

Audio waveforms control the vertical and horizontal movements as well as the brightness of a single beam of light, tracing shapes, points and curves with a direct relationship between sound and image.<\/p>\n

The technique is based on the well-known principle of Lissajous figures, which are a mathematical representation of complex harmonic motion. Originally displayed by reflecting light between mirrors attached to a pair of vibrating tuning forks, we are most used to seeing them on the screen of an oscilloscope, where they can be produced using pairs of electronic oscillators tuned to specific ratios.<\/p>\n

There is a wealth of such experiments from the 1950s onward by major figure such as Mary Ellen Bute, John Whitney, Larry Cuba, Manfred Mohr, Nam June Paik, Ben Laposky, Bill Etra, and Steina & Woody Vasulka, which were all highly inspiration to the development of this library.<\/p>\n
