![]() ![]() Any Quartz Composer patch can be opened and played back in VDMX5. ![]() For a little extra panache, we stuck a computer monitor in Re-bot’s chest that displayed an oscilloscope that was generated from a Quartz Composer patch, and also driven by VDMX5’s audio analysis tool. Resolume 3 supports both VST audio effects and FreeFrameGL openGL video effects. This allowed us to use the built-in audio analysis and clock tools in VDMX5 to detect the amplitude and BPM of the music at the party, and translate it into brightness and color controls on the LEDs that comprised Re-bot’s face. With some light tinkering and guess work, we created an ArtNET node using an Arduino Uno, an ethernet shield and Nathanaël Lécaudé’s ArtNET Library. Instead of shelling out for an expensive DMX/Artnet node to interface with the lights on Re-bots face, we were able to employ a cheap DIY solution. ArtNET is a protocol for sending DMX over a standard network (wifi, ethernet, routers, etc).WS2812 LEDs often come as a rope or strand, and are special in that each bulb on that strand is individually addressable, allowing it’s color or brightness to independent from that of its neighbors.DMX is a digital protocol used on many concert and theater stages to control which lights are on at any given time, and how bright they are.For the non-lighting nerds among us (most of us here at Rehash): But one feature that would come in handy for us would be it’s ability to send DMX via ArtNET messages to Re-bots face which was constructed from WS2812 LED fixtures. It boasts media players capable of handling most digital audio/video formats as well as Quartz Composer Patches and ISF shaders, and a slew of tools for manipulating these formats. Vidvox’s VDMX5 is a highly customizable software tool used by many VJs and installation artists. For the little extra razzle-dazzle, we wanted to give Re-bot an animated face, and in today’s world of open hardware, we were able to do so relatively painlessly and on the cheap. ![]()
