## What it is
The text, diagrams, demos, and source code for the book 'Computer Graphics from Scratch' by Gabriel Gambetta, published by No Starch Press. It teaches raytracing and rasterization algorithms from first principles using language-agnostic pseudocode with no external libraries.

## Use cases
- learn computer graphics fundamentals from scratch
- understand how raytracing works
- learn rasterization and triangle rendering algorithms
- implement a raytracer without external libraries
- study perspective projection and clipping
- find an introductory computer graphics book with interactive demos

## When to choose
- you want to learn graphics algorithms from first principles with minimal math prerequisites
- you prefer language-agnostic pseudocode over framework-specific tutorials
- you want a structured book covering both raytracing and rasterization

## When to avoid
- you need production-ready graphics code or a reusable library
- you want GPU/shader programming or OpenGL/Vulkan/WebGPU tutorials
- you need advanced topics like physically-based rendering or global illumination

## Facets
- artifact type: learning-resource
- maturity: stable
- function: graphics, simulation, documentation
- domain: graphics, education, tutorials
- platform: cross-platform
- tags: book, raytracing, rasterization, computer-graphics, pseudocode, no-starch-press
