SHADER SHOWDOWN

 
Shader Jam @ The Overkill is a chiptune concert with shader based visual support by coders from various locations in Europe.
HOW DOES IT WORK?
During the show, multiple coders in international locations will use a tool called “Bonzomatic” to code visual effects in GLSL or HLSL shader language. Every 0.3 seconds, Bonzomatic sends the changes made in it’s editor window to the central studio in Enschede where another copy of Bonzomatic running on a pc with a powerful graphics card renders the effect in high resolution. The signals from these rendering pc’s and the audiovisual signal from the chiptune artist are fed into a dedicated video mixing pc to compose the audiovisual experience on The Overkill’s livestream.
 

SHADER SHOWDOWN

UHHHHHH OKAY, THAT ALL SOUNDS RATHER COMPLICATED, CAN YOU SHOW ME AN EXAMPLE? 
Sure, this is a show we did earlier this year (with completely different music): https://www.youtube.com/watch?v=vKbmQFKiWYQ 
WHOAH, SHADER CODING SEEMS COMPLICATED, WHERE CAN I LEARN MORE? 
Don’t worry, it looks a lot more complicated than it really is. For learning the basics, we recommend https://thebookofshaders.com/
For examples and inspiration https://www.shadertoy.com/ is a great resource. And if you prefer learning by watching, some coders who participate in our shows have their own Twitch channels: https://www.twitch.tv/evvvvil_ https://www.twitch.tv/flopine https://www.twitch.tv/nusan_fx
THIS SOUNDS COOL, WHERE CAN I FIND THE TOOLS YOU USE?
