Shadertoy Competition 2016



When


3 Jul 1st challenge announcement

10 Jul 1st deadline + 2nd announcement

17 Jul 2nd deadline + 3rd announcement

24 Jul 3rd deadline + WINNER ANNOUNCEMENT


How


This competition is based on remote participation, and it is free!

Every week we'll announce the subject of a new challenge in this page. Once the announcement is done, you'll have a whole week to create and submit your shader. Submitting a shader is very easy, you'll simply have to add name your shader properly with a tag given below and publish it. For example, [SH16A] MyAmazingShader is a valid shader name for the first challenge.

Feel free to publish your shaders any time during the week, we embrace collaboration and will value the original entries appropriately regardless of forked or adapted versions that might come as a result.

After each challenge deadline, points will be given to the submitted shader and displayed in this page for tracking purposes. At the same date, the challenge for the new week will be announced as well.

The winner of the competition will be the author who's three shaders accumulate the most points. Glory and honor are expected for the champion, and perhaps some prizes will be given too!

1st Challenge :: Size Coding!


Description : How small can you make this shader? Making visuals in a small amount of code is a regular exercise in the Demoscene and in Shadertoy. In fact, we already hosted size coding competitions here in Shadertoy, such as the 2 Tweet competition.

For this first challenge, we are going to give you a shader that we wrote, and we want you to make it as small as possible, as counted by Shadertoy's character counter (which is at the bottom of the code editor). However, there are some extra rules. The visuals of the reference image must stay the same after the code optimization. For that purpose we are setting a threshold of a 1% in the number of pixels that can differ between the reference image and your shader's output. We'll perform the check in HD resolution (1920x1080) in two different machines on Windows 10 and MacOSX 10.11.5 both with Chrome 51 and NVIDIA GeForce cards (980M and 750M). This covers the big majority of the Shadertoy community. We'll then average the two pixel counting results to get a more robust and fair pixel count. To aid in this comparison, you can use Photoshop or similar photo editing programs, or the resemble.js website (if you use this, make sure your settings look like this).

The reference shader is https://www.shadertoy.com/view/MdKXD3, which is 5082 characters long, and the image to the right is what the shader looks like (click on it to see a high resolution version):

If your shader is less than 705 characters but you don't see in the list it means it didn't pass the 1% pixel difference test or that it wasn't working on our machines.

2nd Challenge :: Pretty Pixels!


Description : Making the code of a shader tiny has no value unless the visuals it creates are impressive. From demos to movies, games or Shadertoy, pretty pixels often win.


The second challenge of the competition is all about your skill as a creative. Given the theme "Speed", go nuts and create the most visually impressive shader you can! Feel free to add animation, sequencing, (procedural?) music, and whatever Shadertoy feature you need. The rules are simple, impress us with your artistic and technical skills. Right after the deadline we will get a code snapshot of all the shaders to examine.

Show the community that you are the master of graphics, procedural content and animation!

If you have any questions, don't hesitate to ask us or other users in https://www.shadertoy.com/view/4ltGz4

3rd Challenge :: Shader Game!


Description : Every one knows that a Shadertoy runs per pixel, so far we have done tiny shaders and pretty shaders, but what about playable shaders? It is time to show how much of a game can you write in a Shadertoy. Because you and we know GPUs can compute game logic as well!


The third challenge of the Shadertoy Competition 2016 is all about your skill as a generalist programmer, this challenge combines pretty much everything in one Shadertoy : visuals, AI, optimization, rendering, multipass...

Given the theme "80s/90s Games", create an awesome Shadertoy! Feel free to add gameplay, intro sequences, matching sounds, matching visuals, (procedural?) music, and feel free to use WHATEVER Shadertoy feature you need. The rules are simple, rewrite your favorite game from the 80s/90s or invent one that share the visual style of the 80s. Right after the deadline we will get a code snapshot of all the shaders to examine. Beware we already have many games including Pacman game and an Arkanoid, so we'll value more if you make a new game, although these two are good examples of how to implement game logic in Shadertoy, so feel free to use them as reference!

We'll value playability, meaning how complete it is (you can focus in a single level, but within that level, how playable the game is will matter), and ll also overal visual, musical quality and performance of course. If you have any questions don't hesitate to ask us or other users in https://www.shadertoy.com/view/lt33Wr

About Shadertoy

Shadertoy is a web tool that allows developers all over the globe push pixels from code to screen using WebGL. It is free for everybody and it is accessible via www.shadertoy.com.

In less that two years, its users have created thousands of fragments shaders that explore a wide variety of real time graphics algorithms such as raymarching, procedural texturing, modeling and animation, fractal geometry, image compression, volumetric rendering or motion blur.

Shadertoy is also a social platform, a place for professionals and students alike to learn and teach about visuals, interactions, reactivity, modeling, GPU internals and shading.
