Vector Synthesis with Pure Data and the Vectrex by macumbista

Vector Synthesis - Disembodied Hand from macumbista on Vimeo.

"This video employs my Vector Synthesis library for Pure Data to produce an animated vector image using audio signals, which is then displayed on an XY oscilloscope. Here, the shape being displayed is a 3D OBJ file, rendered as three audio signals -- one for each of the X, Y, and Z axes -- with rotations applied to all three dimensions. Display monitor is a 1950's tube oscilloscope which got hot enough to toast bread during the making of this video."

More examples below - don't miss the last one. Vimeo still does not support playlists as far as I am aware of, so popping each one up individually here. Also see Vector Video Synthesis with a Vectrex and Cocoquantus by Hainbach.


Vector Synthesis Scan Processing - Turbulent Vortex from macumbista on Vimeo.

This video employs my Vector Synthesis library for Pure Data to make Rutt-Etra style scan processing of a video image, which is then displayed on an XY display using audio signals. The luminosity of the pixels being scanned controls the brightness and displacement of the oscilloscope beam. Additional modulations of the beam by audio signals create the turning, Scanimate-style 3D effects seen here. The display monitor is a hacked Vectrex game console, and a version of the same audio signal sent to the monitor can heard in the audio track.
