3-WAY SHADER SHOWDOWN

Shader Showdowns are a high-energy, graphically impressive visual livecoding event. Since its inception at WeCan in 2013, the Shader Showdown format has grown in popularity amongst different demoparties across the world and has been a regular event at Revision ever since.

Programmers face each other off, live on stage, coding GLSL shader effects from scratch with no outside assistance besides the DJ pumping some beats. The crowd gets to watch the code evolve on the big screen, enjoying the action and cheering on the participants.

The objective is simple: At the end of the 25 minutes, whoever gets more votes wins and goes through to the final. The winner of the final gets the crown for being the Revision shader showdown champion.
We will have a bracket elimination tournament with rounds of 3 contestants per round. Usual Shader Showdown rules apply:

  • Every battle lasts 25 minutes, and you have to write all code from scratch.
  • Battle timer will be paused for all contestants if there is some technical issue with one of the machines.
  • All code has to be written in GLSL using the latest version of BONZOMATIC
  • A set of textures will be provided for each round (including the Revision logo).
  • Competitors are welcome to bring their own keyboard (without memory function), we will have support for different languages installed.

Commentators will be discussing and explaining the code during the sessions. Audience will be able to vote live.

Here are some impressions from last year event:

SHADER ROYALE VJ SESSION

As part of a live concert or DJ set a Shader Jam VJ sessions will be held.

As visuals for this we will host a massive shader royale jam session, open to anyone in the world with a network connection and a copy of networked BONZOMATIC to participate remotely.

Expect dozens of participants live-coding their shaders and some pre-prepared surprises. Participants can also leave at any moment, and we will keep showing the latest version of their shader. The creations will be shown on rotation at the big screen throughout the DJ set, effectively working as a VJ system to the session.

If you are interested to participate, please check this page.

Contact totetmatt or psenough for any questions. This is what it looked like last year.

ALGORAVE JAM

Last year saw the raise of algorave software an notably strudel that popularized the concept of algorave and livecoding music. This year at Revision, we are therefore organizing an algorave jam.

  • 15 / 20 min set per participants
  • Any livecode based platform is possible
  • VJ optional
