Extra info and code examples

LaserBoy can translate laser vector art into standard, 48KHz, 16 bit, multi channel RIFF WAVE file format and play those files with independent sample shifts between the channels for proper time alignment between the scanners and the color modulation devices (per color). Waves made with LaserBoy can be played from any surround sound card in any OS. LaserBoy can open its own generated wave files and convert them back into vector art. LaserBoy provides a full set of points optimization routines including distance spanning, corner dwelling and the ability to minimize total points distance by rearranging the order and direction of lit segments within a frame. With a DC modified 8 channel sound card and some outboard electronics, LaserBoy is currently outputting full motion, 16bit X, Y position, 24 bit RGB color projections at 48 thousand points per second. Creating waves of any integer sample rate is possible. 48KHz is only a limitation of the sound cards that are currently in use.
