Shadertoy / Raymarching

Single quad pixelshader effects have become common in 1kb and 4kb intros. You raymarch your entire scene inside the pixelshader.

The most common tool to do single quad pixelshader effects is Shadertoy.

Here are some resources for learning raymarching and graphics coding in shadertoy:

• iq’s formulanimations tutorial series
• Mercury’s Signed Distance Functions Library local copy
• Shadertoy Hackaton @ NVScene 2015

4K Procedural Graphics

A relatively recent trend of democompos has been the 4kb procedural graphics executable compo. Where the executable under 4 kilobytes creates a single still image procedurally.

If you can find a list of those entries on pouet:

Some great information on creating procedural graphics can be found in iq’s website:
