Real-time 3D synth software & IDEs list (demoscene, mapping)

# Real-time 3D synth software and IDEs list (demoscene, videomapping, light shows, game design, promo demos)
# This software is for creative, modern artists, VJs, to mix audio, video and light and make some cool performances
# All software is fully OPENSOURCE, FREE, CROSSPLATFORM (suitable for main platforms: Linux, Win, Mac & others)
# Including some game engines, editors and libraries that gives you similar capabilities
# Note: not mentioning programming languages itself (there are SOOO many good out there)
# Note: not including RPG, adventure/quest or similar game engines / editors (post is about DEMOstrating not playing)
