Filmed in December of last year, this specialized laser system at LasX Industries in Minnesota is capable of drawing on surfaces at a rate of up to 6 meters per second. In this example, a design by Andy Gikling is executed in a two-step process. First, the laser moves back and forth in a more familiar raster mode similar to an inkjet or typical laser printer, but at the 1:40 mark things get insane as the system switches to a “vector” process and starts drawing all over the place in real time. If I understand this correctly you’re seeing almost 100,000 vectors drawn in about two minutes and thirty seconds.
