## What it is
A workshop-style tutorial by Electric Square introducing raymarching with signed distance fields, covering SDF shape combination, raymarching loops, lighting, shadows, texture mapping, and post-processing. It is educational material with example shaders rather than a reusable software library.

## Use cases
- learn raymarching from scratch
- understand signed distance fields
- learn shader-based rendering techniques
- implement soft shadows and ambient occlusion in shaders
- recreate Shadertoy-style raymarched scenes
- teach a graphics workshop on distance fields

## When to choose
- you want a guided, step-by-step introduction to raymarching and SDFs
- you learn best from workshop material with progressive examples
- you want to understand techniques used in games like Claybook

## When to avoid
- you need a production-ready rendering engine or library
- you want a rasterization or triangle-mesh pipeline tutorial
- you need maintained software with ongoing releases

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, simulation, developer-tools
- domain: graphics, tutorials
- platform: cross-platform
- tags: raymarching, signed-distance-fields, shaders, shadertoy, workshop, rendering, game-development, gpu
