## What it is
A minimal 3D software renderer written in a single 700-line C file, designed as a tutorial for understanding fixed-pipeline software rendering. It implements CVV clipping, depth buffering, perspective texture mapping, and polygon edge rasterization with no third-party dependencies.

## Use cases
- learn how a software 3D renderer works
- understand rasterization and perspective texture mapping
- study a minimal fixed-function graphics pipeline in C
- teach computer graphics fundamentals with readable code
- see how depth buffering and CVV clipping are implemented
- use as a starting point for building a custom software renderer

## When to choose
- you want a small, heavily commented codebase to learn 3D rendering internals
- you need a dependency-free single-file example of a rasterizer
- you are teaching or studying computer graphics pipeline concepts

## When to avoid
- you need a production-grade or performance-optimized renderer
- you want GPU acceleration or hardware rendering
- you need a full game engine or programmable shader pipeline

## Facets
- artifact type: learning-resource
- maturity: stable
- function: graphics, simulation
- domain: graphics, tutorials
- platform: windows, cpp, cross-platform
- tags: software-renderer, rasterizer, 3d-graphics, fixed-pipeline, educational, single-file, game-development
